System Configuration

Created from a completely new concept that is based on modular architecture, this group of next
generation data acquisition systems is called DARWIN (Data Acquistion and Recording
Windows).
Today many data acquisition networks are increasingly being linked together. More than ever
before, large volume, high speed, accurate, easy-to-use communication functions are essential in
many disciplines.
In the world of measurement and control where the number of measurement points has increased
sharply, the ability to acquire information from a large number of points easily and economically
is crucial. Interfacing to a personal computer allows simplified utilization of the information
while improving quality and efficiency.
DARWIN is based on a unique, new concept to meet these needs. The art of measurement is
revolutionized by DARWIN which integrates functions of conventional recording and data
logging.
Most existing data acquisition equipment has been the all-in-one type in which the measurement
section and display/recording section are contained in one box. While this simplifies operation on
the one hand, it is difficult to adapt to changes in the measurement environment and also makes
expansion difficult.
DARWIN uses a data acquisition engine and remote I/O modules which are completely separate
from each other. It is an entirely new product line which quickly and flexibly copes with various
restrictive conditions and changes in specifications.
Supported by a personal computer, a whole line-up can be created starting with the data
acquisition systems DA series which performs data logging. For example, using a printer as the
output device, the equipment becomes a hybrid recorder (DR series).
Two models are available in the DR series: the DR230 and DR240. The DR 230 is a desk-top
hybrid recorder, and the DR240 is a panel-mount hybrid recorder (component type).

1.2 Product Overview
This product is a hybrid recorder which can record and measure from small-scale 10-ch data up to
widely distributed 300-ch multi-point data.
The number of measurement points can be expanded up to a maximum of 300-ch by connecting
up to six subunits (DS400/DS600) to a main unit (DR232/242). Using dedicated extension cables
between units, interconnections can be extended up to 500 m. Since measured objects scattered
over a wide area can be wired fast and with a minimum of wiring, a flexible, extensive
measurement system can be configured. The input modules to be incorporated in the DR232/242
or DS400/600 can be selected from the following, to suit your measurement conditions:
• Universal input module and DCV/TC/DI input module
Temperature, DC voltage and contact signals can be measured, but cannot be connected to the
main unit.
• mA-input Module
This module can directly measure DC currents ranging from -20 mA to 20 mA since it contains
shunt resistors. It cannot be connected to a system's main unit.
• Power Monitor Module
This module can measure the effective voltage, effective current, active power, reactive power,
apparent power, frequency, power factor and phase angle for an AC voltage or AC current input.
It is available in either a single-phase or three-phase model. This module cannot be connected to
a system's main unit.
• Strain Input Module
This module can measure strain. It is available in either a model with built-in 120- or 350-Ω
bridge resistors or a model with NDIS terminals where bridge resistors are connected externally.
The module cannot be connected to a system's main unit.
• Pulse Input Module
This module can measure pulses. It cannot be connected to a system's main unit.
• Digital input module
This module can measure contact signals. It cannot be connected to a system’s main unit.
• Communication interface module
This module is necessary when communicating with a personal computer. Measurement
conditions can be set and data acquired via the communication interface (GP-IB, RS-232-C, etc.)
of this dule. This module can only be connected to the main unit.
• Alarm module
This module can output alarm signals as contact signals. The module can be connected to the
main unit or the subunit.
• DI/DO module
This module allows a signal to be output in the case of alarm, failure, or chart end and a remote
control signal for the product to be input. The module can be connected to the main unit or the
subunit but only one module in all units.

Note
When the following handling is done, it is necessary to carry out “system construction” to operate the
instrument correctly. After executing system construction, confirm the module information. For details,
see page 9-16.
• Connection (including addition or replacement)/removal of subunits, or unit number setting (see page 37)
• Mounting (including addition or replacement)/removal of modules

Cu10WEED, Cu10BAILEY, Pt100 (1mA) high resolution, Pt100 (2mA) high resolution, JPt100
(1mA) high resolution and JPt100 (2mA) high resolution.
Contact Input
The type of contact input can be selected from voltage level input or contact input, and recording
can be set ON or OFF per channel. In case of the voltage level input a voltage level up to 2.4V
results in recording OFF, whereas a voltage level of 2.4V or more results in recording ON.
DC Currents
DC currents ranging from -20 mA to 20 mA can be measured by means of the built-in 250-Ω
shunt resistors.
AC Voltages/Currents
The effective voltage, effective current, active power, reactive power, apparent power, frequency,
power factor and phase angle can be measured. The measuring range is common to all terminals.
The input terminals of the module with this input mode, unlike those of modules with other input
modes, are not consistent with a setup screen in terms of the channel number.
Strain
The module for this input mode supports the single-gauge, single-gauge three-wire (not yet
supported by the DU500-14 module), adjacent-side two-gauge, opposed-side two-gauge and fourgauge methods. If you have connected any new strain gauge or changed the measuring range, go
through initial balancing before starting measurement.
Pulses
The module for this input mode can measure the number of pulses per second on a channel basis
or detect the on/off states by means of any variations occurring in the instantaneous value every
second. Once you connect the pulse input module, you can sum up values without the need for
the computing function.

Skipping Input Channels
This function allows skipping measurement, recording and display of channels you are not using.
Measurement, recording and display will not be done for the skipped channels.

Reference Junction Compensation (RJC)
This function is to be used when measuring temperatures using thermocouples. The voltage
generated by a thermocouple depends on the temperature of the spot of measurement and the
reference junction temperature. Reference junction compensation is a function which
compensates the temperature at the side of the measurement instrument to 0 degrees C.
To compensate for the environmental temperature an internal circuit can be selected, or
compensation by a fixed compensation voltage value (external) can be set.

Functions

Thermocouple
Measurements can be done after selecting the type of thermocouple per channel. The available
types are R, S, B, K, E, J, T, L, U, N, W and KPvsAU7FE.
Reference Junction Compensation (RJC) can be set to either use Internal RJC (INT) or External
RJC (EXT) per channel.
Burnout function can be set OFF per channel or it can be selected in which direction the trend line
will move if burnout occurs (right or left)

2.2 Measurement Input Functions

Scan Interval
• The duration of time (one scan) in which the measurement of all channels is carried out, is
called the scan interval.
• This interval can be set to any value from 0.5 second to 60 seconds. The shortest is 300 ch/500
ms (varies with the shortest measurement period of the input module).

A/D Integration Time
This instrument measures the input signal after putting it through an A/D converter. In order to
minimize the noise imposed on the input signal, specific integration times exist.
The integration time can be selected from 20ms (50Hz), 16.7ms (60Hz) and 100ms (10Hz).
When “AUTO” is selected, the integration time will be automatically decided according to the 50/
60Hz frequency of the power supply.
AUTO does not function if the instrument is the subunit (DS400/DS600) of the DC power supply
model (Selecting “AUTO” will set the A/D integration time to 20 ms (50 Hz)). If you are using
the instrument on a 60-Hz power supply, set the A/D integration time to 16.7 ms (60Hz).

Input Filter
A filter can be set ON/OFF to reduce normal mode noise. Effects on normal mode noise are as
follows depending on the filter being ON/OFF (theoretical values).

2.3 Recording Functions
Chart Speed
The speed at which the chart moves when performing trend recording can be selected from any
value between 1 to 1500mm/h.
Two types of chart speeds can be set. When you are not using the Event/Action function, which
will be described later on in this manual, chart speed 1 will be valid. When the Event/Action
function is being used, you can select whether chart speed 1 will change to speed 2 according to
the event status.

Two types of recording modes are available; analog trend and logging mode. The default setting
is analog trend mode.
Analog Trend Mode (refer to the next page for a recording example)
Trend Recording (Dot recording)
The recording principle is that, according to measurement data and recording conditions, the
correct position on the chart will be decided and on that position the dot will be printed. Trend
recording conditions consist of the following.
• chart speed
• channels to be recorded
• recording color (refer to page 2-8)
• recording interval (refer to page 2-8)
• recording span (refer to page 2-9)

Items for Analog Trend Mode
Printing Starting/Stopping Time of Recording
You can select whether to print the time of starting/stopping the recording (refer to page 2-9) on
the right side of the chart. The first time recording starts after the power has been turned ON, only
the starting time will be printed. After that, the current starting time will be printed together with
the stopping time of the previous recording. To the right of the starting time a bar will be printed
as a reference point to the time of starting.
Selecting the Number of Columns for Digital Printouts
You can select how many columns (where one column equals data of one channel) will be used in
one line for printing out measurement data.
Selection of the Pitch of Channel Printouts
You can select at which distance the channel numbers (or tags) will be printed. You can also
select this printout OFF. When tags have been selected, this distance applies to the tag printout.
Selection of the Pitch of Title Printouts
You can select at which distances the title will be repeatedly printed. You can also select this
printout OFF.
Selection of the Scaled Values Printout
You can select the printing pattern for scaled values (refer to page 2-9). You can also select this
printout OFF.
Selection of the Reference Point of Scaled Values
You can select whether or not to print a reference point for the positions of the scaled values.

2.3 Recording Functions

Recording Colors
In the trend recording the color of the recording can be selected per channel. The colors which can
be selected are black, purple, redish purple, navy blue, red, blue, brown, green, orange and
yellowish green.
The recording color of the numerical values in the logging mode is purple only.

Recording Interval
The time during which one scan of trend recording or numerical printout is carried out is called
the recording interval.
Recording interval for trend recording
This recording interval can be selected from AUTO or FIX.
AUTO
The recording interval is decided automatically depending on the measurement (scan) interval
and chart speed in order prevent the dots from overlapping. However, in cases where this
calculation would render the recording interval smaller than the scan interval, the recording
interval will equal the scan interval.
Recording interval = Scan interval × N
where N is an integer satisfying N ≤ 720 / (scan interval × chart speed). 720 is
fixed.
Example: when scan interval is 2s; chart speed is 100mm/h
then N ≤ 720 / (2 × 100) = 3.6
The closest matching integer is 3.
Accordingly, the recording interval becomes 2 × 3 = 6s.
FIX
Recording is carried out at an interval which is the same as the scan interval (2 to 60s)
regardless of the chart speed.
Recording interval for digital printouts
This recording interval can be selected from MULTIPLE or SINGLE
MULTIPLE
Six preset recording intervals (Timer 1 to 6) can be set and a recording interval can be selected
per channel. The timer setting can be selected from relative and absolute.
• Relative time: Time will be counted from the point of turning the power switch ON or of
resetting the timer. Each time the preset length of time is reached (and thus when time is
up), recording will start.
• Absolute time: A reference time is set, and from that time recording will start at preset time
intervals (each time when time is up).
SINGLE
The logging interval is decided automatically depending on the chart speed and the number of
columns for digital printouts.
Recording interval in logging mode
This recording interval can be selected from MULTIPLE or SINGLE
MULTIPLE
Same as for the analog trend mode
SINGLE
From the above mentioned six preset recording intervals, the interval set as Timer 1 will
become the recording interval.

Resetting the Recording Interval (Timer Reset)
This function will reset the elapsed time of the above mentioned MULTIPLE recording interval to
zero. Usually recording will start according to the recording intervals, but when you reset the
elapsed time using this function, the results are the same as for time-up.

2.3 Recording Functions

Recording Span
The maximum value and the minimum value of the measurement range are decided when setting
the type of input. The difference between the minimum value and maximum value which will be
recorded within this measurement range, is called the recording span. The value on the left and
right side of the recording are called the left span and right span respectively.

Starting/Stopping Recording
Usually starting/stopping movement of the chart and trend recording is carried out by pressing the
appropriate key on the operation panel. But movement of the chart and trend recording can also
be started/stopped upon alarm occurrence or by remote control (event/action function).

Chart movement can start by either key operation or event/action function and selected channels
will thus be recorded as trend recording.
Normal Recording
Selected channels will all be recorded regardless of the below mentioned occurrence/release of
alarms or group settings. Recording will start when the chart starts moving.
Trend Recording upon Alarm Occurrence
• Trigger Recording
All channels where an alarm occurred will be recorded. Even when the alarm is released,
recording will continue.
• Level Recording
All channels where an alarm occurred will be recorded. When the alarm is released, recording
will stop.
Group Trend Recording
Channels can be clustered in a group, and only those channels will be recorded.

Recording Zone
The recording span of measurement values on the chart is called recording zone. For each channel
you can set between what locations on the chart the measurement values will be recorded.
It is possible to assign zones so that the analog trend recordings of each individual channel will
not overlap. This setting is only valid for trend recordings in the analog trend mode. The default
setting is the full recording width of 250mm.
The left and right boundary of the recording zone (left position and right position respectively)
correspond to respectively the left and right span of the recording span.

2.3 Recording Functions

Partially Expanded Recording
When carrying out trend recording, partially expanded recording enables you to compress a part
of the recording span in order to examine the expanded (other) part of the span in more detail. The
left boundary of the recording span being 0%, and the right boundary of the recording span being
100%, a segment of the recording span can be compressed. The following example shows a
situation where 25% of the recording span has been compressed. The points A, B, C, D, E and F
before compression correspond to the points A’, B’, C’, D’, E’ and F’ in the figure after
compression. The 25% left of the boundary shows —6 to 0V, whereas the 75% right of the
boundary shows 0 to 6V.

Interpolation Function
When carrying out trend recording and a measurement value differs greatly from the previous
one, the track of the recording changes stepwise in the dot printing. In cases like this,
interpolation will be carried out on the horizontal line to connect the two divergent trend tracks.
When the horizontal lines of channels are to be recorded on exactly the same location, only the
recording color with the higher priority will be used.
The priority of recording colors is black > purple > redish purple > navy blue > red > blue >
brown > green > orange > yellowish green, which means that black has the highest priority. In the
figure below a recording example is given of a horizontal line in the colors black, red and
yellowish green. In the area where red and yellowish green overlap (labeled as a), only red dots
will be recorded, and in the area where black, red and yellowish green overlap (labeled as b), only
black dots will be recorded.
However, at the locations where the recordings diverge after the connecting a horizontal line, all
recording colors will be recorded.

This setting applies to all alarms.

Alarm Reset
You can reset the internal switches and alarm output relays and the corresponding displays. The
previously mentioned alarm acknowledge function has the same function as resetting the alarm
display here. Resetting the internal switches and alarm output relays when the relay hold function
is set to ON has the following affects and depends on the alarm status.
• when alarms occur continuously, the internal switches/alarm output relays will turn to their
non-operative status for a short period but soon change into their operation status.
• when alarms are released, the internal switches/alarm output relays turn to their non-operative
status.

2.5 Standard Computation Functions
Standard computations such as difference between channels and linear scaling can be set with
measurement input settings. A moving average computation is also available.

Difference between Channels
This function conputes the difference between the measurement values of a selected channel
(=reference channel) and any other channel (=destination channel). This can be applied to each
channel in the same unit. The computation formula is as follows:
Result of difference between channels computation = measurement value of destination
channel — measurement values of reference channel

Linear Scaling
This function changes the left and right span of the recording span to left and right scale values
which are converted to a different physical quantity. This can be applied to each channel and a
different engineering unit can be entered for display and printouts.
Example where voltage values are cenverted into linear scaling values

Left span:-2V
(=left scale:-0.1A)

Right span:2V
(=Right scale:1.1A)

Moving Average
This function computes a moving average over a preset number of (K) measurement values. This
function is useful for displaying and recording of unsteady measurement values. The computation
formula is as follows.
Dm= (Mm-(K-1) + Mm-(K-2) + ... + Mm-2 +Mm-1 + Mm) / K
where
Dm
: “m”th average value
Mm-(K-1)
: the measurement value of the “K-1”th measurement before the “m”th
measurement
Mm-(K-2)
: the measurement value of the “K-2”th measurement before the “m”th
measurement
.
.
.
.
Mm-2
: the measurement value of the second last measurement before the “m”th
measurement
Mm-1
: the measurement value of the last measurement before the “m”th measurement
Mm
: the measurement value of the “m”th measurement
K
: number of samples, and an integer ranging from 2 to 64
At the first computation, the measurement value of the first measurement will be multiplied by
the number of samples, after which the average will be taken. The measurement values of the
second and later measurements will replace these in turn, after which the average will be
calculated each time.

3.2 How to Install
Installation Conditions
The instrument must be installed in a location where the following conditions are met.
Ambient temperature and humidity
• Ambient temperature: 0 to 50°C
However, in case you mount the AC power supply model subunits DS400/DS600 directly to a
panel, or if you apply the DIN rail, or mount them in a rack, it is possible to use them in a range
of –10 to 60°C.

WARNING
• When the environmental temperature is 50°C or more, the temperature
of the rear panel may rise to more than 70°C. Thus, touching the rear
panel under these circumstances has the danger of sustaining burns.
• To prevent a fire, always use the instrument in a vertical position, and
do not block the upper side of the modules (a space of at least 3cm is
necessary).

• Ambient humidity: 20 to 80%RH for –10 to 40°C, 10 to 50%RH for 40 to 50°C, 5 to 30%RH
for 50 to 60°C (However, no condensation should be present.)
• Installation location: Room
• Installation height: Altitude up to 2,000 m

Note
Internal condensation may occur if the instrument is moved to another place where both the ambient
temperature and humidity are higher, or if the temperature changes rapidly. In case of thermocouple input,
this might result in erroneous measurements. In those cases, allow the instrument to achieve eqailibrium
with to its new environment for at least one hour before starting operation.

Never install the instrument in any of the following locations:
• in direct sunlight or near heat sources
• where an excessive amount of soot, steam, dust or corrosive gases are present
• near strong magnetic field sources
• near high voltage equipment or power lines

3.3 How to Connect the Input/Output Modules

WARNING
When connecting the Input/Output modules, make sure to turn OFF the
power to the DR232/DR242/DS400/DS600 to prevent an electric shock
or damage to the instrument.

Setting the Unit Number of each Subunit

Note
When you connect an input module at the location of the setting switch, the switch can not be operated
anymore. Therefore, make sure you set the switch before connecting any input module there.
It is convenient for confirming unit numbers to write each unit number setting on the gray concave surface
at the top of DS600 subunit (or on the left side of DS400 subunit).

Connecting Method
1. Verify that the power to the DR232/DR242/DS400/DS600 has been turned OFF.
2. Remove the cover of the location where the module will be connected. Do not remove any
cover of locations where no module will be connected.
3. Hold the input unit so that the male part of the connector at the back side of the input unit
matches the female part of the receiving connector. Then connect the unit.
4. Fasten the input unit by fastening the two accessory M3 screws.

DS600: Input module + alarm module + DI/DO module: max. six

Note
• No alarm module or DI/DO module can be connected to the right side of an input module, since the rise
in temperature would hinder the measurement accuracy. Verify the type of module by the seal on the top
side.
• Do not connect the universal input module and the power monitor module in slots next to eachother.
Keep them at least 1 slot apart. If you mount the power module immediately beside the universal
module, the measuring accuracy of the universal module may fall out of its guaranteed range because of
the heat radiating from the power module.

Connecting Procedure
Insert the plug of the extension cable in the connector until you hear a click. Since both
connectors are identical, it makes no difference which connector you use. Furthermore, since both
plugs of the cable are identical, you may use either end.
When pulling the plug from the connector, gently press the peg of the plug and pull it forward.

Plug

Points to Note when Using the Extension Cables
• The maximum rated temperature is 60°C;
• Never disconnect the extension cable from the connector by pulling the cable, since this might
damage the signal cable. Always hold the plug.
• When wiring the extension cable through a cable duct, or metal pipe or such, protect the peg on
top of the plug by covering it with tape.
• For extension cables of longer than 50 m connect the plug with copper foil directed towards the
main unit DA100. Applying it in reverse direction might increase noise.
• Fasten the cabels in such a way that no force is applied to the connector or the plug.
• To prevent the wire from snapping, etc. do no apply a tensile force of more than 70N.
Furthermore, do not bend the cable in a radius of 3 centimeters or less.
• For the environmental conditions for wiring, refer to Section 3.11, “Countering Noise” (page 335).

Note
When several sub-units are connected, and the power is turned off of one of them, the other connected subunits which are further away from the main unit will not be recognized anymore.

3.7 Connecting the Signal Lines

WARNING
• To prevent electric shock, always make sure that the power supply is
turned OFF before connecting.
• When 30VAC or 60VDC and more is applied to the output terminal of the alarm
module or the output terminal of the DI/DO module, use double-insulated
wires(withstand voltage performance: more than 2300VAC) for those wires
which apply 30VAC or 60VDC and more. All other wires can be basicinsulated(withstand voltage performance: more than 1350VAC). Furthermore,
use “crimp-on” lugs (for 4mm screws) with insulation sleeves for connecting to
the screw terminal. Make sure that the crimp-on tool must be one specified by
the crimp-on lugs manufacture, and that the crimp-on lugs and tool must be
matched to the wire size. To prevent electric shock, do not touch the terminal
after wiring and make sure to re-apply the cover.

CAUTION
• Do not apply an input voltage exceeding the following levels to each
terminal of the universal or DCV/TC/DI input module. Otherwise, the
internal circuits may be damaged.
• Max. allowable input voltage
2 VDC range or less, RTD, TC and DI (CONT): ±10 VDC
6 to 20 VDC range, DI (LEVEL): ±60 VDC
• Max. common mode noise voltage : 250 VACrms (50/60Hz)
For the maximum voltage of the remote control signal input, see “DI:
remote control of recorder functions” on page 14-14.
• The overvoltage category of each input module is CAT ll (IEC 1010-1).
1 Check that the power switch of this instrument is turned off.
2 Remove the terminal cover. (the figure below shows DU100-11.)

Terminal cover
Screws for fastening the cover

3 Fasten the signal wires to the terminals as shown in the figure on the next page.
4 Re-apply the terminal cover and fasten the screws.

Note
Make sure that the equipment connected to the signal in-/output conforms IEC (CSA) 950 or IEC (CSA)
1010. Also, make sure to use cables that conform to IEC (CSA) standards.
In case you are using an internal RJC in case of thermocouple input, the following considerations are
necessary to stabilize the temperature at the terminals. Always make sure to re-apply the terminal cover;
The thermal capacity of the wiring should be small (cross sectional area of less than 0.5mm2); Minimize
outside temperature fluctuations as much as possible.
To prevent noise, make sure to ground each unit at the grounding function terminal (below the power
switch) together at one point.
Refrain from wiring the input signals parallel. However, if you do, then the following considerations are
necessary. Ground all equipment at the same point; Do not turn the power of other equipment ON/OFF
during operation; Do not use the burnout function.

3.7 Connecting the Signal Lines

Wiring AC Input Signal Lines (Power Monitor Module)

WARNING
• For hazard prevention, ALWAYS provide protective grounding before
connecting measuring leadwires.
• When connecting any object being measured, ALWAYS turn off the
power to the object. It is extremely dangerous to connect or disconnect
interconnecting leadwires with the power to the object left on.
• Exercise utmost care to avoid connecting any current-mode circuit to a
voltage-input terminal or any voltage-mode circuit to a current-input
terminal. Wrong connection may result in damage to the circuit or
equipment being measured or the DR232 or DR242 recorder itself, as
well as bodily injury.
• Fuses are not built into voltage- and current-input terminals. ALWAYS
install a fuse on the interconnecting leadwire. Use a fuse that will not
permit the voltage or current being measured to exceed the maximum
ratings of an AC input module.
The maximum voltage and current that can continuously be imposed on
an AC input module are as follows:
Voltage: 250 Vrms; current: 5 Arms
• To avoid electrical shock, ALWAYS attach the terminal cover in place
after the completion of wiring to the terminals so that the terminals
cannot be accidentally touched.

CAUTION
• In wiring, use double-insulated leadwires that have sufficient
withstanding-voltage and current-carrying-capacity margins against the
voltage and current being measured and meet the ratings at which they
are used.
• ALWAYS clamp measuring leadwires with the wire clips to prevent the
wires from being disconnected from their terminals. As the measuring
leadwires, use wires 0.2 to 2.5 mm2 (AWG14 to 25) thick so they can
be fastened securely with the wire clips.
• The power monitor module is a product belonging to Installation (Overvoltage) Category CAT II.

3.8 Connecting an Extension Module to Extension
Bases
Using an extension module and extension bases, you can install input modules at a location
distant from the sub-unit(s). The module and bases are powered from the sub-unit and, therefore,
can be located even in a place where there is no power source nearby.

Installing an Extension Base

WARNING

3
Installation and Wiring

• For fire prevention, use extension bases in an upright position.
Do not cover up the extension base's module (allow a clearance of at
least 3 cm around the module).

Ambient Temperature and Humidity
Use an extension base under the following environmental conditions:
• Ambient temperature: –10˚ to 60˚C
• Ambient humidity:
20 to 80% RH at -10˚ to 40˚C
10 to 50% RH at 40˚ to 50˚C
5 to 30% RH at 50˚ to 60˚C
Use the extension base in a condensation-free condition.

Note
Condensation may occur if you move the extension base from an area of low humidity to an area of high
humidity or if any drastic temperature variation takes place. In addition, a measurement error will result if
the DR recorder is in the thermocouple input mode. In that case, allow at least one hour for the extension
base to adjust to the ambient atmosphere before using it.

Do not install the extension base where:
• it is exposed to direct sunlight or there is a heat source nearby;
• soot, steam, dust and/or corrosive gas is relatively abundant;
• there is a strong electromagnetic source nearby;
• there is high-voltage equipment or a power line nearby;
• it is exposed to severe and/or frequent mechanical vibration; or
• it is not positioned stably.
Desk-top or Floor Installation
Attach the two supplied shoe plates onto the extension base with two screws (4-mm screws 16
mm long, supplied as standard accessories), as shown in the figure on the left below. Then, place
the extension base in an upright position. If the base is liable to fall on its side after wiring, fix
the shoe plates with the four supplied screws (4-mm screws 12 mm long) using the through-holes
(for 4-mm screws) of the shoe plates.
Direct Mounting on Panel
According to the figure on the right below, fix the extension base onto a panel by fastening the
four corners with the supplied screws (4-mm screws 12 mm long).

IM DR232-01E

3-27

3.8 Connecting an Extension Module to Extension Bases
Connecting Extension Bases to an Extension Module
Verify that the power of the DR/DS400/DS600 has been turned off before connecting the
extension module/extention base.
Mount the extension module onto the sub-unit. The module cannot be mounted to the DR
recorder itself. Wire the extension module to the extension base with an extension cable. You
can wire a maximum of three extension bases to one extension module at the same time. It is not
possible, however, to wire extension bases in such a manner that the total sum of modules already
mounted on the sub-unit and the extension bases being wired exceeds the maximum number of
modules (four for the DS400 sub-unit and six for the DS600 sub-unit) allowed for mounting on
the sub-unit.
Either a 10-channel universal input module (DU100-11 or DU100-12) or a 10-channel DCV/TC/
DI module (DU200-11 or DU200-12) can be mounted onto each extension base.

When Using the Accessory Power Cord
DR232/DS400/DS600 (when using the accessory power cord)
Follow the warnings below to avoid electric shock or damaging the instrument.

WARNING
• Connect the power cord only after confirming that the voltage of the
power supply matches the rated electric power voltage for this
instrument.
• Connect the power cord after checking that the power switch of this
instrument is turned off.
• To prevent electric shock or fire, always use the power cord supplied by
Yokogawa.
• Always use protective grounding to prevent electric shock. Connect the
power cord of the instrument to a three-pole power outlet which has a
protective ground terminal.
Do not use the function grounding ( marked terminal) under the power
connecting part as the protective ground terminal.
• Never use an extension cord that does not have protective grounding,
otherwise the protection feature will be negated.
• An AC outlet (auxiliary for the DS400/DS600) should be used to supply
power to the DS400/DS600 using a power cable(DV400-051)
separately available. Do not use this AC outlet to supply power to the
other equipments nor use other cables for the power connection.
Otherwise, the current flowing through the AC outlet will exceed the
permissible current, thereby resulting in the fuse blowing, overheating
or burning may occur.

Follow the warnings below to avoid electric shock or damaging the instrument.

WARNING
• Connect the power wires after checking that the power supply is turned
off to prevent electric shock.
• To prevent fire, use 600 V PVC insulated wire (AWG18) for both power
and ground wiring (cross section of 0.83 mm2 or thicker, anti-galvanic
corrosion finish, insulation thickness more than 0.8 mm, insulation
resistance more than 50 MΩ/km at 20°C, approved EN60 320
(VDE0625)), or equivalent cables.
• Units equiped with screw type terminals should only be used in panel
installations.
• Before turning on the power, always ground the protective ground
terminal. Do not use the function grounding terminal ( marked
terminal) under the power connecting part as the protective grounding
terminal.
• For AC power and ground wiring, use “crimp on” lugs (for 4mm screws)
with insulation sleeves. Make sure that the crimp-on tool must be one
specified by the crimp-on lugs manufacture, and that the crimp-on lugs
and tool must be matched to the wire size.
• To prevent electric shock, do not touch the terminals after wiring.
• An AC outlet (auxiliary for the DS400/DS600) should be used to supply
power to the DS400/DS600 using a power cable(DV400-051)
separately available. Do not use this AC outlet to supply power to the
other equipments nor use other cables for the power connection.
Otherwise, the current flowing through the AC outlet will exceed the
permissible current, thereby resulting in the fuse blowing, overheating
or burning may occur.

3.11 Countering Noise
Types and Features of Noise Sources
Commercial Power Supply
It is necessary to consider both 50 and 60Hz as noise components. It is important to note that a
power supply line in which a thyristor or inverter is incorporated functions not only as an “energy
surplus line”, but also as a “supply surplus line”.
Thyristor (SCR)
A thyristor is used to control power through ON/OFF modulation of commercial power by
controlling the phase angle.

or

*Load

Thyristor
Unit

*heaters, etc.
phase angle
Thyristor waveform

When the thyristor turns ON or OFF, a pulse noise is superimposed on commercial power supply,
and its pulse width is approximately 1µs. Accordingly, thyristor noise can be defined as follows.
· thyristor noise = commercial power supply + pulse noise
Inverter
Commercial power supply is converted to direct current by a rectifier (sometimes the thyristor is
used as the rectifier to stabilize direct current) and then modulated by a switching transistor and
finally converted into alternating current at the desired frequency (from tens to hundreds of Hz) to
drive a motor, for example. If the load to be driven is a fluorescent lamp, the frequency is tens of
kHz. Accordingly, inverter noise can be defined as follows.
Inverter noise = commercial power supply + pulse noise (high density) + variable low frequency
noise
Since the density of pulse noise is high compared to that of a thyristor and in addition, there is
variable frequency noise, it is difficult to consider a countermeasure for inverter noise.

Relay
A relay is frequently used to amplify alarm and temperature controller outputs. However, since a
counter-electromotive force (counter e.m.f.) is produced by coil inductance when the relay is
turned off and the e.m.f. becomes noise, care must be taken. Due to chattering at the relay contact,
tens to hundreds of kHz noise occurs mainly in bursts. Thus, the noise energy often becomes high.
Transceiver
In large-scale plants, transceivers are often used for communications between the field and the
control room. Although W/G of the Japanese Electric Measuring Instruments Manufacturers
Association recommends to use transceivers covering a wave band of 27MHz, smaller-sized
transceivers for the 140 or 470MHz wave band are often used.
Noise Simulator
To test the immunity to pulse noise (mainly thyristor noise), a noise simulator is often used. A test
noise of approximately 1kV for 0.8µs is used synchronously with the power supply frequency.
Since data acquisition equipment is often used for measurements of equipment subjected to the
pulse noise test, the influence of noise must be considered.

Propagation of Noise
• Noise is propagated in the following three ways.
Conduction:
noise is conducted through a power line, input wiring, etc.
Electrostatic induction:
noise leaks through capacitances between wires and instruments.
Electromagnetic induction: a loop in the input line, etc. induces an AC voltage by detecting the
AC magnetic field.
In real applications, the above three propagation paths are not independent of each other. Their
combination propagates noise to the equipment and causes problems.
• Examples of noise propagated through each of these paths are given below.
Conduction:
inverter noise, relay noise, thyristor noise, and noise caused by
surface temperature measurement of a power transistor, etc.
Electrostatic induction:
commercial power supply noise such as the hum of audio
equipment, relay noise, etc.
Electromagnetic induction: magnetic leakage flux from a power transformer or motor, magnetic
field from a high-frequency induction furnace, the rotating magnetic
field of a power generator (Cu10Ω), etc.
The figure on the next page shows the propagation paths using practical examples.

Common Mode Noise (ECM)
Noise generated between the signal source and the ground of a measuring instrument. Since it is
applied to both the H and L input terminals in phase with one another, it is also called in-phase
voltage.
Normal Mode Noise (ENM)
This is an unfavorable noise that is superimposed on a signal voltage. Since it is a voltage
between the H and L terminals, it is also called the line voltage, or since it is a voltage in series
with the signal voltage, it is sometimes called the series mode voltage.

(0.2k to 10kHz)

3.11 Countering Noise
In the figure on the previous page, due to common mode voltage ECM, noise currents i1 and i2
flow through the impedance to grounds Z1 and Z2 and coupling impedance Z3, resulting in the
generation of normal mode noise ENM between input terminals H and L. Like this, common mode
noise is converted to normal mode noise. The amp is equipped with a built-in filter and in case of
output EO the normal mode noise will be eliminated. This rate of conversion is called the
common mode rejection ratio and expressed by the following equation.
EO

• Common mode rejection ratio (CMRR)=20Log

ECM

(dB)

Since the actual CMRR is expressed using the ratio of an error component output caused by
common mode noise to common mode noise, it contains the normal mode rejection ratio (NMRR)
expressed by the following equation.
• Normal mode rejection ratio (NMRR)=20Log

EO
ENM

(dB)

The NMRR is a value that shows the ability to reject the output error (normal mode noise
component: ENM) by normal mode noise. Thus, this is also a very important value which shows
the resistance-to-noise characteristics of the measuring instrument.

Basics of Anti-Noise Measures (part 2)
Decreasing and Increasing Impedance
As described in the previous section, conversion of common mode noise into normal mode noise
causes an error in the measured output. In other words, prevention of such a conversion is the key
to anti-noise measures. As can be understood from the previous section, it is important to take the
following measures to reduce normal mode noise.
· reduce the wiring resistances R1 and R2, including the resistance of the wires.
· increase the coupling impedance of common mode voltage ECM.
These are called the decrease and increase of impedance as basics of anti-noise measures.
In the above discussions, anti-noise measures have been described on the assumption that
common mode noise has already been given. In real applications, common mode noise often
occurs owing to grounding resistance as shown in the figure below.

L
One-point grounding

Grounding resistance and ECM
Ground current

In such a case, perform one-point grounding as indicated by the dotted line, as an extreme
example of decreasing impedance, to equalize the potentials of the signal source and the
instrument. Rejecting common mode noise in this way is the basics of anti-noise measures.

Anti-Noise Measures in the Instrument Itself
Pulse width modulation type A/D converter (PWM type A/D)
This instrument uses a feedback pulse width modulation type A/D converter and has the
following features:
• Linearity and stability are good because of the feedback effect.
• Integration type A/D converter ensures excellent noise suppression.
If the integration time is equal to the noise period, the positive and negative sides of the shaded
part in the figure below cancel each other out and thus the average value becomes zero.

Installation and Wiring

Normally, an integration time of 20ms (50Hz) or 16.7ms (60Hz) is selected depending on the
commercial power supply frequencies. A 100-ms integration mode is added to the instrument to
achieve superior noise rejection. However, when using the 100ms setting, the smallest
measurement interval is longer than in case of the 20ms or 16.7ms setting. The integration effect
enables the PWM A/D converter to perform the following two functions.
• Rejection of frequency determined by the reciprocal of the integration time and frequencies
which are whole multiples of that frequency;
• First-order lag filter provided with cut-off frequency proportional to the reciprocal of the
integration time.
The following table compares the integration times of 16.7ms, 20ms and 100ms.

• Shielded and twisted pair (prevention of electromagnetic coupling): an increase
of impedance
If it is difficult to keep the noise source away from the measuring instrument due to space
limitations, the use of a shielded twisted pair is effective.
• electrostatic coupling can be completely cut off by shielding;
• for a magnetic field, shielding with a magnetic material (iron, permalloy, etc.) can be
employed. However, there are many restrictions on this use and perfect shielding is
impossible. Therefore, use of a twisted pair is preferable.
Voltage em induced by the coil is proportional to the area of the coil.
=> The smaller the area of the coil becomes, the smaller the noise becomes.

If the directions of coils 1 and 2 are reversed by twisting, as shown, if the areas of the two coils
are equal, the induced voltages of the coils offset each other and total induced voltage em

(Note) Across the relay or solenoid coil, a counter-electromotive force is produced by an
inductive load. This phenomenon may damage the contact or, as the noise source,
cause a malfunctioning of the equipment, and have an unfavorable effect on the
entire system.

• If a relay contact is connectd to the input
of the system components, apply the
measure shown in the figure at the right
to the relay coil. Otherwise, a counterelectromotive force produced across the
coil may be induced on the contact side
through the relay's internal coupling or
coupling between the lines, and may
cause a malfunctioning of the equipment.

Anti-Noise Measures for PC Connection
When connecting the instrument to a PC, it is recommended to apply ferrite cores (e.g.
ZCAT3035-1303 from TDK) to the interface cable as a noise countering measure. Apply a ferrite
core on both sides of the cable as shown below, when the noise persists, apply more ferrite cores.

Channel No.
The first three characters are used for displaying the channel number. Delete “The first character
always displays “0”.” “A” will be displayed in the case of optional computation channels.
If you selected TAG at the channel No./TAG setting in the set-up mode (refer to 10.2 on page 104), the assigned tag will appear for each channel.
• The first 7 characters of the TAG setting will be displayed;
• If the TAG setting consists of only spaces, the channel number will be displayed instead;
• If the first character of the TAG setting is a space, the 2nd to 8th character will be displayed.
Difference between Channels (delta)
One character is used to let you know that difference between channels (delta) is displayed.
However, it will not be displayed in the case of optional computation channels.
Only if you selected the difference between channels (delta) as the input type, “d” will be
displayed here.
Alarms
Two characters are used for displaying alarms. One channel is used in the case of optional
channels.
When an alarm occurs, the kind of alarm will be displayed. When in one channel several alarms
occur at the same time, the priority of display becomes H > L > dH > dL > RH > RL. For details
on H, L, dH, dL, RH and RL alarms, refer to page 8-2.
Measurement Values
Seven characters are used for displaying the measurement values. The decimal point uses up one
character. Nine channel is used in the case of optional computation channels.
When a measurement value does not reach the following value, “– *****” will be displayed.
• DC voltage: a minimum value of the measuring range – (max. value – min. value) × 0.05
• TC/RTD: min. value of the measurement range –10°C
• Linear scaling: –32000, or a minimum value of the recording span – (max. value – min. value)
× 0.05
When a measurement value exceeds the following value, “+ *****” will be displayed.
• DC voltage: a maximum value of the measuring range + (max. value – min. value) × 0.05
• TC/RTD: min. value of the measurement range +10°C
• Linear scaling: +32000, or a maximum value of the recording span + (max. value – min. value)
× 0.05
If the input module is not connected properly, “ XXXXXX” will be displayed.
While waiting for an input signal “ OOOOOO” will be displayed.
Engineering Units
If the channel number has been selected to appear on the display, six characters are used for
displaying engineering units. If TAG has been selected to appear on the display, only three
characters are used for displaying units. Only the first three characters of the unit setting will then
be displayed, even if the first character of the unit setting is a space.
When “ XXXXXX” or “ OOOOOO” are displayed as measurement value, no engineering unit

The two characters following the first channel number show the number of the last channel to
which settings apply.
• Setting range: See description of the above “The first channel number.” The number of the last
channel cannot be smaller than the number of the first channel. When both channel numbers are
equal, settings will only apply to that particular channel. When you have set the first channel
number and you move the cursor to the last channel setting, the channel number of the first
channel setting will appear here.

5.1 Setting the Type of Input and Recording Span

Setting the Recording Span
The measurement range is decided according to the type of input. The recording left and right
span must lie within the measurement range. However, the recording span is 0 to 1 for the DI
input type. The value on the left side of the SPAN menu shows the left span, and the value on the
right side of the SPAN menu shows the right span.
For the remote RJC, the setting range for recording span is the same as that for the reference
channel.

Setting the Input Type/Recording Span/Linear Scaling

Selecting the Type of Input
The following types of input can be selected. The default setting is VOLT.
• SKIP
Measurement, recording and display (except for page display) will not be carried out.
Measurement, recording and display will be carried out for the next channel whose input type is
not set to SKIP.
• VOLT (DC voltage)
This input type can be selected from 20mV, 60mV, 200mV, 2V, 6V, 20V and 50V. Refer to
chapter 14 for the measurement range of each setting. The default setting is 2V.
• TC (thermocouple)
This input type can be selected from R, S, B, K, E, J, T, N, W, L, U and KP (KPvsAU7Fe).
Refer to chapter 14 for the measurement range of each setting. The default setting is R.
• RTD (resistance temperature detector)
This input type can be selected from PT1 (Pt100 1mA), PT2 (Pt100 2mA), JPT1 (JPt100 1mA),
JPT2 (JPt100 2mA), PT50 (Pt50 2mA), NI1 (Ni100 1mA SAMA), NI2 (Ni100 1mA DIN), NI3
(Ni120 1mA), CU1 (Cu10 GE), CU2 (Cu10 L&N), CU3 (Cu10 WEED), CU4 (Cu10
BAILEY), PT1S (Pt100 1mA high resolution), PT2S (Pt100 2mA high resolution), JPT1S
(JPt100 1mA high resolution), JPT2S (JPt100 2mA high resolution) and J263B (J263*B). Refer
to chapter 14 for the measurement range of each setting. The default setting is PT1.
• DI (voltage level: LEVL; contact:CONT)
This input type can be selected from LEVL and CONT.
In case of LEVL, a voltage of less than approx. 2.4 V will be recognized as “0 (OFF)”, whereas
a voltage of approx. 2.4V or more (max. allowable voltage is up to ±60 VDC) will be
recognized as “1 (ON)”.
In case of CONT, an open, externally connected contact to which no voltage is applied, will be
recognized as “0 (OFF)”, whereas a closed contact will be recognized as “1 (ON)”.
The default setting is LEVL.
• DELTA (difference between channels)
Computation can be done only in the same unit. Destination channels should lie within the first
channel No. to the last channel No. range. The number of the reference channel should be lower
than the number of the destination channels. The default setting for the reference channel is 01.
The type of input and the measuring range in the distination channel are the same as for the
reference channel. After setting the DELTA (difference between channels), if you attempted to
change the type of input and the measuring range, setting the difference between channels is
released, thereby the type of input and the measuring range in the destination channel are
returned to their original settings, and the recording span is returned to its initial value.
• RRJC (Remote RJC, available if the instrument is equipped with the optional MATH function)
Reference channel (RJC): Within the setting range of reference channel No.
TC (thermocouple) must be selected as the type of input to the reference channel.
If the channel No. or type of input for the reference channel, or the type of thermocouple is
changed, the alarm and partial compression recording functions will be turned OFF.
If the type of input for the reference channel or the type of thermocouple is changed, the RRJC
settings will be cleared and the type of input and measuring range for the reference channel will
be set to the one which was in effect before the change was made. The recording span will be
set to the initial value of the measuring range.
• mA (DC current, mA input module)
This input can be set only for mA input channels. The measuring range is -20 mA to 20 mA.

Setting the Input Type/Recording Span/Linear Scaling

Setting the Channel Number
This procedure sets the channel number for which you want to show and record the values of a
parameter selected from the effective voltage, effective current, active power, reactive power,
apparent power, frequency, power factor and phase angle which were calculated using the
measured data. Therefore, it does not correlate with the terminals of an input module. In this
procedure, determine from which channel (starting channel) to which channel (ending channel)
you want to include in your configuration.
Starting Channel Number
The first three digits on the main display constitute the starting channel number.
• The first digit is the unit number. The second digit denotes the module number (slot number).
• The configurable range depends on the location where the power monitor module is connected.
See page 3-8 for more information.
Ending Channel Number
The two digits that follow the starting channel number constitute the ending channel number.
Normally, the starting channel number and the ending channel number should be the same. If you
want to skip any consecutive number of channels, enter the range of those channel numbers.
• When you move the cursor from the starting to the ending channel number, the ending channel
number becomes the same as the last two digits of the starting channel number.
Setting the Wiring Method
Select from the following methods:
Single-phase two-wire (1Ph2W)
Single-phase three-wire (1Ph3W; three-wire input modules only)
Three-phase three-wire 2 Voltage 2 Current (3Ph3W-2I; three-wire input modules only)
Three-phase three-wire 3 Voltage 3 Current (3 Ph3W-3I; three-wire input module only)
Three-phase four-wire (3Ph4W; three-wire input modules only)
Setting the Input Range
Select from the following ranges:
250V-0.5A
250V-5A
25V-0.5A
25V-5A
This setting is common to all channels. Any change to this setting also changes the settings of the
rest of the channels. Impose a voltage or current signal to the input module within the limits you
set here.
Setting the Parameter Being Shown and Recorded
A power monitor module measures the voltage or current through the respective channels. The
values that are shown and recorded are not those of the voltage and current being actually
measured through each channel but the values of the parameters you set here.
A combination of parameters being measured is fixed for each group of channels 1-2, 3-4 and 5-6
within the same module. For example, setting channel 1 to P1 (active power 1) sets channel 2 to
VA1 (apparent power 1). In addition, the configurable parameters being measured varies
depending on the wiring method selected. See the lists on the next page for more information.
The respective mnemonics in the lists should be interpreted as noted below:
Vi (i=1, 2, 3) : effective voltage
Ii (i=1, 2, 3) : effective current
V13 : (V1+V3)/2

Precautions in Measurement
• Input the voltage or current being measured at a level between 10% and 100% of the measuring
range. The DR recorder bases its calculations of all other parameters on the frequency of V1.
Extra care must therefore be taken when setting the input level of V1. If the input level fails to
fall within the given limits, there is no guarantee that the measurement of any other parameters
will be reliable.

Note
If you have connected any new strain gauge or changed the measuring range (initialization of settings or
reconfiguration of the system also changes the measuring range back to its default), you must go through
initial balancing. See Section 5.5, “Performing Initial Balancing/Initialization on a Strain Input Channel,”
for more information.

Setting the Input Type/Recording Span/Linear Scaling

Setting the Channel Number
Set the channel number for which you want to configure the type of input, recording span and so
on. In this procedure, determine from which channel (starting channel) to which channel (ending
channel) you want to include in your configuration.
Starting Channel Number
The first three digits on the main display constitute the starting channel number.
• The first digit is the unit number. The second digit denotes the module number (slot number).
• The configurable range depends on the location where the power monitor module is connected.
A strain input module takes up twice the space of a standard-size module. This results in the
number of the slot following the one where the strain input module is installed being a missing
number. See page 3-8 for more information.
Ending Channel Number
The two digits that follow the starting channel number constitute the ending channel number.
• For the configurable range, see “Starting Channel Number” above.
• You cannot enter a channel number that is smaller than the starting channel number.
• If you have entered the same number as the starting channel number, only that one particular
channel is included in your configuration (configuration of the type of input, recording span,
etc.).
• When you move the cursor from the starting to the ending channel number, the ending channel
number becomes the same as the last two digits of the starting channel number.
Setting the Recording Span (SPAN)
Set the left and right spans within the limits of the input range. In the SPAN menu item, the lefthand value is the left span and the right-hand value the right span.

6.3 Setting Recording Zones and Partially Expanded Recording
Setting Recording Zones (ZONE)
This setting specifies the recording zones for each channel. The set left and right position of the
zone correspond to the left and right span set at the SPAN menu (recording span). The left value
of the ZONE menu corresponds to the value of the left position of the zone, whereas the right
value of the ZONE menu corresponds to the value of the right position of the zone.
Zones can be set in 1mm steps and cannot exceed the recording range (i.e. 250mm). The left
position setting ranges from 0 to 245mm, whereas the right position setting ranges from 5 to
250mm. The minimum width of a zone is 5mm. A decimal point cannot be set. The default
settings are 0mm for the left position and 250mm for the right position.
If the instrument is equipped with the optional computation function or floppy disk drive, this
setting can also be made for computation channels A01 to A60.
Partially Expanded Recording (PARTIAL)
This setting specifies whether to carry out partially expanded recording, and if so, which
percentage of the recording span will be compressed and the corresponding boundary value.
If the instrument is equipped with the optional computation function or floppy disk drive, this
setting can also be made for computation channels A01 to A60.
Selecting Partial Recording ON/OFF
ON: Partial recording will be carried out;
OFF: Partial recording will not be carried out.
The default setting is OFF.

Note
If boundary values are to be set for succeeding channels, the decimal point is handled as shown below.
If succeeding channels are set, the decimal point position of boundary values when the measurement range
for each channel setting is different, is that determined for each corresponding range. As a result, it exceeds
the measurable range, an error occurs.
For example, if channels whose measurement ranges are 20 mV, 2 V, and type T thermocouple are set and
the boundary value is set to 10000, the following applies:
The boundary value of the channel whose measurement range is 20 mV: 10.000 mV;
The boundary value of the channel whose measurement range is 2 V: 1.0000 V; and
The boundary value of the channel whose measurement range is type T thermocouple: 1000.0 °C
As the measurement range of type T thermocouple is -200.0 to 400.0 °C, an error occurs for this channel.
For decimal point positions for each measurement range, see Chapter 14, “Specifications.”

Points to Note when Using Partially Expanded Recording
• Partial recording cannot be carried out if the input type of the computation channels is SKIP or
DI or if the computation channels are OFF.
• Partially expanded settings will be automatically canceled when either of the following changes
occur.
• the input type has been changed;
• the measurement range has been changed;
• the recording span has been changed;
• linear scaling settings have been changed;
• the reference channel for difference between channels has been changed.

6.8 Setting Match Time, Moving Average, Interpolation and Groups
Setting the Match Time
MATCH TIME No. (selection of the match time number)
Three kinds of match times can be set.
TIME
Any time between 00 days, 00 hrs., 00 min. and 31 days, 23 hrs, 59 min. can be set in 1-minute
units. The default setting is 01 days 00 hrs 00 min.
If 00 is set to day (DD), HH:MM every day shows the set time. If day (DD) is set to a value
other than 00, HH:MM of DD day every month shows the set time. DD, HH, and MM give the
set numeric values respectively.
The match time setting is used with the event/action function. Refer to 9.1 on page 9-1 for details.
Moving Average (MOVE AVE)
This setting can be set for each channel individually. The number of samples used for the moving
average can be set from 2 to 64. The default value is 0, which means that no moving average is
carried out. The result of the moving average is being displayed/printed.
Interpolation (INTERPOL)
This setting can be set for each channel individually. If the instrument is equipped with the
optional computation function or floppy disk drive, this setting can also be made for computation
channels A01 to A60. The default setting is OFF.
OFF: no interpolation will be carried out.
ON: interpolation will be carried out according to the priority of recording colors. The priority of
recording colors is black > purple > redish purple > navy blue > red > blue > brown > green >
orange > yellowish green.

Setting the Recording Conditions

Group setting (GROUP)
• GROUP No. (selection of the group number)
Up to seven groups can be set.
• G01 to G07
This setting specifies which channel numbers will be included in one group. A “,” is used for
entering a single channel, while a “-” can be used to enter a range of channels. Setting the same
channel two or more times in one group causes an error. For example, if you configure G01 as
003, 001-010, an error will result because 003 is included in this range. The default setting is
001.
• The group setting is used with the event/action function. Refer to 9.1 on page 9-1 for details.

Setting, Displaying and Recording Alarms

RELAY=OFF

8.1 Setting Alarms and Relays (including internal switches)
Selecting the type of alarm
• Select an alarm type for each alarm number from among the following:
• OFF (default set): No alarm is set.
• H: Upper-limit alarm. An alarm occurs when the measured value exceeds the upper-limit
alarm setpoint.
• L: Lower-limit alarm. An alarm occurs when the measured value exceeds the lower-limit
alarm setpoint.
• RH: Rate-of-change upper-limit alarm. An alarm occurs when the measured value changes
in the increasing direction within a certain time (rate-of-change alarm interval) and exceeds
the upper-limit alarm setpoint.
• RL: Rate-of-change lower-limit alarm. An alarm occurs when the measured value changes
in the decreasing direction within a certain time (rate-of-change alarm interval) and exceeds
the lower-limit alarm setpoint.
• dH: An alarm occurs when the difference between two channels exceeds the alarm setpoint.
This only applies to a channel for which interchannel differential computation is selected,
and can be set as a type of alarm.
• dL: An alarm occurs when the difference between two channels exceeds the lower-limit
alarm setpoint. This only applies to a channel for which interchannel differential
computation is selected, and can be set as a type of alarm.
• For details on the rate-of-change alarm interval setting or other basic alarm settings, see Section
10.3, “Select Alarm Interval/Hystresis/Hold/A/D Converter integration Timer/filter” on page
10-8.
• For details on interchannel differential computation, see Section 5.1, “Setting the Type of Input
and Recording Span” on page 5-3.
• Only H (upper-limit alarm) and L (lower-limit alarm) are available for computation channels.
Setting alarm values
Set one alarm value for each alarm number within the following range, depending on the type of
input. The default value is 0 (zero).
• H and L
• VOLT, TC, RTD, DI, and DELTA: Within the measuring range in the related channel. DI
can be set to either 0 or 1.
• SCALE: Within a linear scaling value.
• Computation channel: Within the range specified by the computation function
• RH and RL
• VOLT, TC, RTD, DI, and DELTA: Within 1 to [maximum measuring range minus
minimum measuring range] in the related channel. For example, set 30000 (without using a
decimal point) if the maximum value exceeds 30000. DI can be set to only 1.
• SCALE: Set 1 to 30000 without using a decimal point.
• dH and dL
• When the standard channel uses VOLT: Within the measuring range.
• When the standard channel uses other than VOLT: [maximum measuring range minus
minimum measuring range] to - [maximum measuring range minus minimum measuring
range]
• For the type of input, see Section 5.1, “Setting the Type of Input and Recording Span” on page
5-3.

Note
When setting alarm values in continuous channels, use the decimal point as follows:
The decimal point of an alarm value when the continuous channels have different measuring ranges
should be in the position determined by the individual measuring range. If the decimal point is outside
the measuring range, an error occurs. For example, if channels with measuring ranges 20 mV and 2 V,
and a type T thermocouple channel, are all set to an alarm value of 10000, then the alarm values in the
respective channels are as follows:
10.000 mV in the 20 mV measuring range channel
1.0000 V in 2 V measuring range channel
1000.0°C in the type T thermocouple channel
A type T thermocouple has a measuring range from -200.0 to 400.0°C, so an error results. For details on
the decimal point positions in individual measuring ranges, see Chapter 14, “Specifications.”

Event/Action Function and Other Functions

Selection of events (EVT)
Select any event from among the following:
• NONE — releases the event/action setting.
• REMOTE
• This menu is displayed only with the DI/DO modules that are recognized as system modules
(see page 9-16).
• When a remote control signal is applied, the action is executed.
• There are 12 control signals available. Select any control signal from these numbers for
event setting. Remote control signal terminal numbers are applicable for this selection. See
page 3-19 for the remote control terminal numbers.
• ALARM
If an alarm occurs, the action is executed. See Section 8.1, “Setting Alarms and Relays
(including internal switches),” on page 8-1 for setting alarms.
• RELAY
If the selected internal switch or relay is operating, the action is executed. When the alarm
module or the DI/DO modules are not recognized as system modules (see page 9-16), the relay
is set to OFF. See Section 8.1, “Setting Alarms and Relays (including internal switches),” on
page 8-1 for setting internal switches and relays.
• CHART END
When the end of the chart is detected, the action is executed.
• TIMER
• If the selected timer’s set time is up, the action is executed. Six timers are available. Select
any from among these timers. See Section 6.1, “Setting the Recording Mode/Engineering
Unit/Recording Channels/Recording Interval,” on page 6-3 for the timer setting provided
earlier in this manual.
• In combination with the level action, the action is repeated alternately between executing
and stopping each time the timer’s set time is up.
• MFUNC KEY
• When the M.FUNC key on the operation panel is pressed, the action is executed. Select
either M.FUNC 1 or M.FUNC 2.
• In combination with the level action, the action is repeated alternately between executing
and stopping each time the M.FUNC key is pressed.
• MATCH TIME
• When the set time is reached, the action is executed.
• There are three types of applicable MATCH TIMEs. Select any of them. For details, see
Section 6.8, “Setting Match Time, Moving Average, Interpolation and Groups,” on page 617 provided earlier in this manual.
• In combination with the level action, the corresponding action is repeated alternately
between executing and stopping for each set time.

9.1 Setting Event/Action Functions
Selection of actions
An action that can be selected varies depending on the events and edge or level action. See the
individual procedures. The following describe all actions available.
• ALARM ACK
This allows alarm acknowledgment. For the applicable functions, see Section 2.4, “Alarm
Function,” on page 2-15.
• ALARM RST
This resets alarms. When the “RELAY” is selected for an event, this function cannot be
selected.For the applicable functions, see Section 2.4, “Alarm Function,” on page 2-15.
• TIMER RST
This resets timers. For the applicable functions, see Section 2.3, “Recording Functions,” on
page 2-8.
• RECORD
• ON: Starts recording. The recording format is set individually. For details, see Section
10.2, “Setting Recording Format,” on page 10-3.
• OFF: Stops recording. The level action does not include record ON/OFF functions.
• When the level action is set, the ON/OFF functions using the RECORD key are disabled.
• The edge and level actions cannot be set simultaneously.
• For the level action, only one action is available.
• MANUAL PR
This enables manual printing. For applicable functions, see Section 2.3, “Recording
Functions,” on page 2-12.
• DIGITAL PR
• Digital printing starts in the analog trend mode. The recording intervals depend on the timer
setting (see Section 2-8). When the event/action functions are set, normal digital print
functions are disabled.
• Only one function can be set in the event/action functions.
• MSG PR
• Prints messages. For details, see Section 7.3, “Starting Message Printing,” on page 7-3.
• Select any message from the corresponding codes 01 to 20.
• MSG DISP
• Displays messages. For details, see Section 7.3, “Stating Message Printing,” on page 7-3.
• Select any message from the corresponding codes 01 to 20.
• To cancel the message display, press any key.
• SPEED CHG
• Changes chart speed 1 to chart speed 2. When the recording interval is set to automatic
(page 6-3), the recording interval is also changed. When the event is released, the chart
speed and recording interval return to their original positions.
• Only one function can be set in the event/action functions.
• GR TREND
• This executes the recording in a channel in which the group setting (page 6-17) has already
been made. For this, set the dot-recording (see on page 10-4) to “ GROUP” and start
recording by key operations following the “RECORD” given above.
• Select any group from G01 to G07.
• Only one identical group can be set in the event/action functions.

Note
· If Chart End appears, counter-actions such as RECORD ON are not executed.
· Actions such as RECORD or SPEED CHG may operate later than an event occurrence. For example,
with RECORD set in the action setting, if an alarm occurs, the measured values in that condition are not
recorded. This is because recording operations are delayed due to an action operation.

Selecting the temperature unit (TEMP)
The temperature unit can be selected from the following;
• °C which is the initial value, or
• °F

Note
• In the User’s manual all functions and operations are explained using the °C unit. When using the °F
unit, replace the °C unit with the °F unit. For the measurement range/measurement accuracy and
maximum resolution in case of using the °F range, refer to the following table as a replacement of the one
on page 14-2.
• Measurement range: Refer to the following table;
• Measurement accuracy/maximum resolution: Replace the values using the following formula
°F = (°C value × 9/5) + 32
• When changing the temperature unit as descibred above, other settings will be initialized at the same time
and therefore, all settings need to be done again. This initialization will be the same initialization as
described on page 9-17.
• In order to make the set or selected contents effective, the contents must be registered. For details, see
page 10-23.
• To return from the SET UP menu to the operation display mode, select END in the main menu. For
details, see page 10-23.

The DR recorder calculates and processes an hour's, day's or month's worth of measurement or
computation data into instantaneous values, averages and/or sums to print the results in a
predetermined format at a preset time. The results can be delivered using the communication
function or printed on a recording chart. For more information on output using the
communication function, see the separate DR130/DR231/DR232/DR241/DR242 Communication
Interface User's Manual (IM DR231-11E).
You select from the choices in the FUNC menu, which opens when you press the FUNC key, to

Time to Make Report (START TIME)
Set the time to make a report in the format day of month : time. Define the day of month field
within a 01-28 range and the time field within a 00-23 range.
Hourly reports:
The DR recorder makes reports every hour on the hour (1:00, 2:00, . . ., 23:00, 24:00). For
cumulative summation, it resets the cumulative sum at a preset time.
Daily reports:
The DR recorder makes reports at a preset time or times. For cumulative summation, it resets the
cumulative sum at the preset time of a day.
Monthly reports:
The DR recorder makes reports at a preset time of the day.
Report Channels
There are sixty report channels, from R01 to R60. You can assign channels for measuring objects
being computed or computation channels and the type of computing on a report-channel basis.
When making a report of computed data, let computing start before letting the report making start.

Sum and Cumulative Sum
Sum:
The total sum over an hour for hourly reports, the sum over a day for daily
reports or the sum over a month for monthly reports. The DR recorder resets
this value each time it makes any of these reports.
Cumulative sum:The total sum up to the preset time to make a report in the case of hourly
reports or the sum up to a preset time of the day to make a report in the case of
daily reports. The DR recorder resets this value at each preset time or at each
preset time of the day for report making. The DR recorder does not perform
cumulative summation for monthly reports.
As an example, the following illustrates the process of summation and cumulative summation for
hourly reports. The example shows the case where the preset time to make a report is 8:00.

Unit of Summation (SUM UNIT)
Such input data items as the flowrate that have a unit in /sec, /min, /hour or /day, when simply
summed, give results of computing different from their actual values. This occurs because the
unit of such a data item differs from that of the measurement interval. In that case, you can take
the output after having converted the unit of summation so it matches that of the input data item
applied.

10.12 Working with the Report Function
Printing Reports on a Recording Chart
You can print created reports on a recording chart. If you set the REPORT PRINT menu item to
on during the configuration of the report function, the DR recorder starts printing automatically at
the same time it finishes making a report. You can also print reports by pressing the FUNC key,
opening the FUNC menu and then selecting the REP RECALL START menu item. In that case,
take note of the following:
• You can print the latest report only, irrespective of whether it is an hourly, daily or monthly
report. Neither daily nor monthly reports are printed if you print immediately after an hourly
report was created.
• Care must be taken when the REPORT PRINT menu item is set to automatic printing. If the
time for automatic printing arrives while printing is enabled from the FUNC menu, the DR
recorder will no longer print reports automatically.
• Even if you have configured the DR recorder so it prints a daily report in the enhanced format,
it prints the report in the standard format if it has been more than an hour since the report was
created.
• Even if you have configured the DR recorder so it prints a monthly report in the enhanced
format, it prints the report in the standard format if it has been more than a day since the report
was created.
To stop printing, press the FUNC key and select REP PRINT STOP from the FUNC menu. The
following are examples of how a daily report prints.

10.12 Working with the Report Function
Starting/Stopping Report Making
Report making can be started or stopped in two ways:
• Press the FUNC key and select REPORT_START or REPORT_STOP from the FUNC menu.
• Use the event/action functions to define the start/stop of making a report for the following
events:
Edge action: You can define every event as an edge action to start/stop report making.
Level action:You can use remote, alarm, relay and end-of-chart signals as events to start/stop
report making. Report making starts at the same time that any of these events
occur. Report making stops when the event clears.

Note
• If you start report making, all reports created up to that point are reset.
• When report making is in progress, you cannot make changes to measurement channels, measuring
ranges or dates and times nor can you copy information on the ranges.
• If any computed data are included in your report making, let computing start first and then get report
making started. If you fail to enable computing, the data in your reports will become meaningless
because no change takes place on the computed data.
• If you want the start of computing and report making enabled at the same time, use the event/action
functions to assign both of these instructions to the same event as actions.

Time Relationship Between the Settings of the REPORT_START/STOP Menu Items
and Report Making
The following figure shows the time relationship between the settings of the REPORT_START/
STOP menu items and report making.
Report n

Time to make report

denotes the point in time a report is created.

• Data items included in the first round of report making after the start of report making are fewer
in number than those included in the second and subsequent rounds of report making.
• The DR recorder samples data before stopping report making. The report created when the DR
recorder stops making reports thus includes those data.
• If the time when report making is started coincides with the time the report is created, the start
of report making precedes. Thus, no report is created.
• The data sampled at the same time report making started are included in first round of report
making. The report created when the DR recorder stops making reports thus includes those
data.
• If you have defined timer and match-time signals as events using the event/action functions so
the time report making starts matches the time the report is created, data items included in the
first round of report making are one data item greater in number than those included in the
second or any subsequent round of report making.
Processing Against Absence of Measurement
Measurement may not take place if the DR recorder is loaded beyond its processing capability. If
absence of measurement occurs, the DR recorder compensates for the missing data with the data it
measures immediately after recovering from the absence of measurement (the data for the period
with no measurement thus match those acquired immediately after recovering from the absence of
measurement).

10.12 Working with the Report Function
If Power Failure Occurs While Report Function Is Active
The DR recorder takes different actions depending on the length of a power failure.
If the power failure time is longer than 12 hours:
The DR recorder makes a report immediately after it recovers from the power failure and then
stops making reports. It does not execute printing based on the settings for automatic printing.
Print out reports either using the communication function or from the FUNC menu.
Results of computing: The DR recorder computes data measured up to the point immediately
before the power failure.
Time of report making:The time when the power failure occurred.
If the power failure is less than 12 hours:
The DR recorder takes different actions depending on the time it recovers from the power
failure.

3. Positive overflow/negative overflow: *
If more than one faulty data item occurs at the same time, the DR recorder prints them while
giving priority to a data item with a smaller number among the numbers noted above.
Notes on daylight savings time
When the function to shift the time scale between standard time and daylight savings time is
specified, the report for the day to shift from standard time to the daylight savings time seemingly
includes data for only a 23-hour day and, at the same time, the report for the day to shift daylight
savings time to standard time seemingly includes the data for a 25 hour day.
If you specify the time to make a report at the same time as the shift from standard time to
daylight savings time, or vice versa, the report will be generated based on the time scale after the
shift.

is 512 KB.
Saving method (WRITE MODE)
The following three methods are available.
• DIRECT
Measured/computed data is saved immediately after setting has been completed. Saving is
complete when data of the specified length has been saved.
• TRIGGER
The event/action function is used to save only one file of measured/computed data when an
event takes place. This function is useful when you want to save measured/computed data in
case of an alarm.
• REPEAT
Same as TRIGGER, except that measured/computed data is saved each time an event takes
place, until the RAM disk is full or saving is stopped by the operator. Events which occur
during saving will be ineffective.

The data write interval at which data is saved can be selected from the following.
INTVL: Same as measurement interval. Every set of measured/computed data is saved.
1 min, 2 min, 5 min, 10 min: Saved at the specified interval.
LOGIC: One piece of data per channel is saved each time the event specified by DATA WR
(event/action function) occurs. For a detailed description of the event/action function,
refer to 9.1, “Setting Event/Action Functions” (page 9-1).
Data length (WRITE LENGTH)
Used to set the number of pieces of data per channel. Select one of the following options.
10, 20, 30, 40, 50, 100, 200, 300,. 400, 500, 1k, 2k, 3k, 4k, 5k, 10k, 20k, 30k, 40k, 50k
Some options cannot be selected depending on the number of channels to be saved or the number
of computation channels.
Pre-trigger (PRE TRIGGER)
If REPEAT or TRIGGER has been selected as WRITE MODE, data which occurs before the
trigger (event) is activated can be saved within the specified data length. Set the trigger timing in
units of percentage (%) of the specified data length in steps of 10%.

11.1 Saving Measured and Computed Data
Data format
Measured/computed data is saved in binary format.
Data size
Data size can be calculated using the following equations.
Measured data: 2 bytes / 1 data
Computed data: 4 bytes / 1 data
Header: 576 + 64 x (number of measurement channels + number of computation channels) bytes
Data size = 576 + 64 x (number of measurement channels + number of computation channels) +
(number of measurement channels x 2 + number of computation channels x 4 + 6) x specified
data length
For instance, if the number of channels is 10, number of computation channels is 5 and specified
data length is 5k, the data size can be calculated as follows.
Data size = 576 + 64 x (10 + 5) + ((10 x 2 + 5 x 4) + 6) x 5k = 231,536 bytes
Status display during saving
The following status symbols are displayed in the sub-display 2 (lowest display section).

11.2 Reading Measured and Computed Data
Measured/computed data is read from the internal RAM disk.
Reading methods (READ MODE)
The following two methods are available.
• DIRECT
Data is read at the measurement intervals immediately after setting has been completed.
• TRIGGER
The event/action function is used to read data at the measurement intervals when an event takes
place. This function is useful when you want to compare data before an event with data after
an event.
Displaying the contents of the file
The following information of the read file is displayed.
Sample rate (intervals at which data was saved)
Date/time on which a trigger (event) took place
Saving start date/time in the case where saving was carried out in DIRECT mode
Model type on which data was saved
Number of pieces of data per channel
Data No. in effect when the trigger (event) took place
Always "1" if saving was carried out without DIRECT
or PRE TRIGGER settings made.

Channel is changed if this digit is changed.
Status of channel Nos. 201 to 230 ( : Data available, : No data available)
Status of channel Nos. 231 to 260 ( : Data available, : No data available)

Reading data from a floppy disk
To read data which has been copied to a floppy disk from the RAM disk, it is necessary to copy
the data from the floppy disk to the RAM disk. However, data in ASCII format cannot be read.
Status display during reading
The following status symbols are displayed in the sub-display 2 (lowest display section).
It is not possible to make media settings other than reading stop setting while measured/computed
data is being read.
M : Reading is in progress.
T : Awaiting a trigger

Saving/Reading Measured,
Computed and Set-up Data

Displaying/recording the read data
To display or record the read data, it is necessary to assign the read data to computation channels
A01 to A60 using the SET menu. This assignment is still possible even if the instrument is not
equipped with the optional computation function.
Assign the following channels to computation channels A01 to A60.
• M001 to M300: Read data for measurement channels
• MA01 to MA60: Read data for computation channels
If the instrument is equipped with the computation function (/M1 model), read data can be
calculated in the same way that measured/computed data is calculated.
Like measurement channels, it is possible to make the unit, alarm, zone, partial compression, tag,
linear interpolation, dot color and recording settings for computation channels A01 to A60.
However, only the upper-limit and lower-limit alarms are available. Specify channel Nos. A01 to
A60 when specifying channel Nos.

11.4 Reading Set-up Data
Set-up data for the SET mode or SETUP mode is read from the internal RAM disk or a floppy
disk.
Loading methods (LOAD MODE in SET mode)
The following two methods are available.
• DIRECT
Setup data is loaded immediately after setting has been completed.
• TRIGGER 1/TRIGGER 2/TRIGGER 3
The event/action function is used to load set-up data when an event takes place. This function
is useful if you want to record data when an event takes place, with different recording spans.
One event must be set for the LD_TRIG1, LD_TRIG2 and LD_TRIG3 actions during event/
action function setting. For a detailed description of the event/action function, refer to 9.1,
“Setting Event/Action Functions” (page 9-1).
Confirming the set-up data
To confirm the read set-up data for the SETUP mode, specify SETUP = STORE in the same way
as the SETUP mode setting.

Note
• If set-up data saved on another instrument (DR series recorder) is loaded and does not match this
instrument’s configuration, settings which do not comply with the configuration cannot be made.
• No reading is allowed during computing.
• The communication function remains disabled during reading.

Types of files that can be copied (COPY TYPE)
• DATA: copies measured and computed data.
• PANEL: copies set-up data.
Saving measured/computed data to a floppy disk
Data measured or computed using the instrument cannot be saved to a floppy disk directly. It
must be saved to the internal RAM disk first, then copied to a floppy disk.
It is not possible to change the file name when copying the file.
Displaying/recording measured/computed data saved on a floppy disk using the
instrument
To use the instrument to display or record measured/computed data copied to a floppy disk, the
file containing measured/computed data must be copied from the floppy disk to the RAM disk.
However, data in ASCII format cannot be copied.
It is not possible to change the file name when copying the file.

11.6 Copying in ASCII Format
Measured/computed data in the internal RAM disk is converted to ASCII data, then copied to a
floppy disk. The identifier is .CSV.
Conversion channel (COPY CH)
Used to select a channel whose data is to be converted to ASCII data. Measurement channels and
computation channels are arranged in the order of 001, 002, ... 560, A01, A02, ... A60. For
instance, if “559-A02” is specified, data for channels 559, 560, A01 and A02 will be converted.
Conversion data (COPY DATA)
Used to specify the conversion range for the channels specified by COPY CH. Enter the
conversion start data No. and end data No.
Data size
When measured/computed data is converted to ASCII data, 12 bytes will be used for each data
set. Thus, data size can be calculated as follows.
Data size = 178 + 20 x number of conversion channels - 2 + (24 + 12 x number of conversion
channels -1) x number of data sets to be converted
Copying is not possible if destination’s memory size is insufficient.

Note
When a file is copied to a floppy disk, the file creation date will be replaced by the date on which the file is
copied.

* Previously measured data or computed data. In the case of computed data, the value is set to 0 when the
computation is reset. At the start of the computation, if the computation was reset, the value is “0”. If it
was not reset, the value is the last value of the previous computation. The value that can be specified
inside the() is limited to the input channel number (001 to 060) or the computation channel number (A01
to A60). Each computing equation can be used once.
** When specifying HOLD(A):B or RESET(A):B, A and B are channel numbers or computing equations.
These can be used once in the beginning of the computing equation.

Limitations in computing equations
Multiple operators can be used in 1 computing equation. But, there are following limitations.
- Number of characters that can be used : 40 characters
- Total number of channel numbers and constants: 16 (Computation erroro ccurs when 16
exceeded, and the computed result becomes +OVER or -OVER)
- Computation channel numbers: Computation channel numbers less than the current
computation channel number can be used as variables within the computing equation.
Example: A02=001+A01 ← Computation channel numbers greater than or equal to A03 can
not be used in this computation.
- Statistical operators (TLOG. or CLOG.) can only be used once in 1 computing equation.
Computation channel
A total of 60 computation channels are available (A01 to A60).
Constant
A total of 60 constants can be set (K01 to K60).
Flag (F01 to F16)
Flags can be set in computing equations as constants (1 or 0). Flags are normally 0, but it is set to
1 when a certain event occurs according to the event/action function. For example, if the
computing equation is set to
NOTF01*TLOG.SUM(001),
and FLAG:F01 is set as an edge action of an event/action, F01 becomes 1 when the event occurs.
This causes NOTF01 to become 0 and the SUM of channel 001 to become 0.
Computation range
If the result exceeds ±10308 during computation, an overflow will occur.
Data applicable for computation
The following data is used for computation.
• Measured data: Specified by channel No. (001 to 560).
• Computed data: Specified by computation channel No. (A01 to A60).
• Constant: Value specified for K01 to K60.
• Group data: Measured data of channels belonging to a group. Specified by group No. (G01 to
G07). This is applicable only for CLOG.
• Communication input data: Data written to the instrument’s memory via communication
interface. Specified by data No. (C01 to C60).
• Data on internal RAM disk: Applicable only for the DR232-1/DR242-1 (equipped with a
floppy disk drive). Measured/computed data saved in the internal RAM disk. Specified by
M001 to M560 (for measured data) or MA01 to MA60 (for computed data).

12.1 Overview of the Computation Function
Handling of data for computation
For computation, measured/computed data is treated as a value having no unit. For instance, if
the measured data for channel 001 is 20 mV and the measured data for channel 002 is 20 V, the
computation result of “001 + 002” will be 40.

12.2 Setting a Computation Equation
A computation equation can be set for up to 60 channels (A01 to A60).
Setting the mode
If “A01-60 MODE=ON” is specified as in the example given on the previous page, the same
equation can be set for channels A01 to A60. To set an equation for one channel only, specify,
for instance, “A01-A01 MODE=ON”.
Computation equation
In addition to operators described on page 12-1, the following symbols can be used in equations.
(/) : Used for ( ) setting.
K : Used if equations contain constants K01 to K60.
M : Used to specify the measurement channel No. for which the data saved on the RAM disk
is to be re-generated. Applicable for the DR232-1/DR242-1 equipped with a floppy disk
drive.
A : Used to specify the computation channel No. for which the data saved on the RAM disk is
to be re-generated. Applicable for the DR232-1/DR242-1 equipped with a floppy disk
drive.
C : Used to specify communication input data (digital data).
G : Used to specify the group No. for which CLOG (computation of data of a group measured
on the same time) is to be used.
Restrictions in equations
Computation channel No
• The specified computation equation for a computation channel No. can contain only
computation channel Nos. as variable which are equal to or smaller than said computation
channel No.
(Example) A02=001+A01
In this example, any computation channel No. which is equal to or greater than A03 cannot be
used.
• Either TLOG or CLOG can be used in an equation.

Note
• Each equation must consist of up to 40 characters.
• The total number of channels and constants to be used for each equation is 16 or smaller.

Setting the recording span
Set the recording span for computation results. The setting range is from -9999999 to 99999999.
The decimal point can be placed in five positions, as represented in x.xxxx, xx.xxx, xxx.xx,
xxxx.x, xxxxx.. The unit specified in 6.1, “Setting Recording Mode/Engineering Unit/Recording
Channel and Recording Interval” (page 6-1) will be used.
LEFT : Sets the left-limit value of the recording span.
RIGHT: Sets the right-limit value of the recording span.

Note

If the computation ON/OFF, computation equation or span setting is changed, the alarm and partial
compression recording settings for the corresponding channel will be reset.

12.2 Setting a Computation Equation
Example of Settings of CLOG
When computing the maximum, minimum, maximum minus minimum, sum and average of data
measured at the same time on multiple channels, you must configure groups beforehand.
Example of settings where the averages for channels 001, 002, 003, 004, 006 and 008 are
computed:
Configuration of groups:
In the SET menu, assign channels 001, 002, 003, 004, 006 and 008 to group G01, as shown
below:
SET=GROUP
GROUPNo.=G01
G01=001-004, 006, 008
Define the computational expression that computes the average of group 1, as shown below:
CALC=CLOG.AVE (G01)
Computation on Pulse Input Channels
For pulse input channels, you can define the operator TLOG.PSUM (XXXX) where the DR
recorder does not have the optional MATH function (/M1 option). The type of computation is the
integration of the count if the measurement mode is set to RATE (instantaneous count mode) or
the integration of the turn-on time if the measurement mode is set to GATE (instantaneous turnon time mode). In either case, the integrated value is the sum of values measured every second.
For this reason, even if you set the measurement interval to 0.5 second, the DR recorder retains
the same value for one second.
Set the maximum count and turn-on time using SPAN. The maximum configurable value is
99999999. Set the interval of summation (integration interval) as a relative or absolute time by
setting the event to TIMER with the event/action functions. Set the action to TIMER RESET.
See Section 9.1, “Setting Event/Action Functions,” (on page 9-1) for details on how to configure
the event/action functions.
If the computational expression is written as TLOG.PSUM (XXX) in the system reconfiguration
where the PULSE INPUT MODULE filed is set to “not installed,” the computational expression,
alarm settings and partial settings are initialized. In addition, if the DR recorder is not a model
with the optional MATH function (/M1 option), groups to which computation channels were
assigned by the group setting and logic boxes to which actions of the MATH function were
assigned by the logic setting are initialized.
ON
State of contact
OFF
ON
Time
0
Integration interval

You can select whether to treat a result of the computational expression TLOG.PSUM (XXXX)
exceeding 99999999 as an overflow or to continue computing with the value following 99999999
reset to 0. For details on how to make the selection, see Section 12.5, “Setting Action to Be
Carried Out in Case of Computation Error and Setting the Time Axis for TLOG SUM.” The
result of computing in this context is that resulting from a separate calculation of TLOG.PSUM
(XXXX). If you set the computational expression as TLOG.PSUM (XXXX)*100, the above
action does not take place even if the result of the calculation TLOG.PSUM (XXXX)*100
exceeds 99999999. If you have made such selection as to continue computing even if the result
exceeds 99999999, the value subsequent to 99999999 is reset to 0. If the next measured value is
4 after the result of computing has proved to be 99999999, that value is not reset to 0 but is
counted in sequence from 0 to 3, giving 3 as the result.

12.4 Starting/Stopping Computation
Event/action function
An example of setting the event/action function is given below.
Set the event/action function if you want to reset the results after computation is carried out for a
certain period of time, then resume computation.
1. Set TIMER RST for the MFUNC KEY:1 event.
2. Set MATH:START for the same MFUNC KEY:1 event.
3. Set MATH:RESET for TIMER:1 event.
4. Set the mode for TIMER No.1 to RELATIVE and TIME to “00 01:00”.
After the above settings have been made, press the MFUNC1 key. Timer 1 will be reset
according to the above steps 1 and 2, then computation starts. After elapse of one hour,
computation results will be reset according to step 3, but computation will still continue. When a
further hour elapses, computation results will be reset. The above operations will be carried out
repeatedly until computation is stopped.
For a detailed description of the event/action function, refer to 9.1, “Setting Event/Action
Functions” (page 9-1). Refer to pages 2-9, 6-2 and 6-3 for a description of timers.

12.5 Setting Actions to be Carried out in Case of Computation Error and Setting the Time Axis for TLOG SUM
Displaying/recording in case of computation error (MATH ERROR)
Used to determine whether +OVER or -OVER be displayed/recording in case of computation
error.
Time axis scale for TLOG SUM (TLOG TIME SCALE)
For TLOG.SUM of time series, data is added at each measurement interval. However, in the case
of an input having unit of /s, /min or /h like flow rate, the computation result will differ from the
actual value, if addition of data is carried out. In this case, setting TLOG TIME SCALE
according to the unit of the input will cause the data measured at measurement intervals to be
processed according to the unit of the input.
For instance, if the measurement interval is 2s and input value is 100 m3/min, the computation
result will be 30000 after the elapse of one minute, since 100 is added every 2 seconds. Setting
TLOG TIME SCALE to /min will cause the measured data to be multiplied by 2s/60s at each
measurement interval, thus making the result close to the actual input value.
If this function is set to OFF, simple addition of data will be carried out.
Process of abnormal data during TLOG or CLOG (TLOG CH ERROR)
Used to select the process method for abnormal data obtained during TLOG or CLOG.
• ERROR : Abnormal data is processed as a computation error.
• SKIP
: Abnormal data is ignored and computation is continued.
Process of overflow data during TLOG or CLOG (TLOG CH OVER, SUM or AVE)
Used to select the process method for overflow data obtained during TLOG or CLOG.
• ERROR : Overflow data is processed as a computation error.
• SKIP
: Overflow data is ignored and computation is continued.
• LIMIT : Overflow data is treated as the next data for computation.
Measurement channels to which linear scaling is applied: Specified scaling upper-/lower-limit
Measurement channels to which no linear scaling is applied: Upper-/lower-limit of the
measuring range
Computation channels: Specified LEFT/RIGHT value
Processing of the results of TLOG.PSUM computation
• OVER: If the result of a separate calculation of TLOG.PSUM (XXXX) exceeds 99999999, the
DR recorder goes into an overflow.
• ROTATE: If the result of a separate calculation of TLOG.PSUM (XXXX) exceeds 99999999,
the DR recorder resets the value subsequent to 99999999 to 0 and continues computing.
The process is effective only when a pulse input module is installed.

Calibration

Overview
We recommend that you calibrate the DR232 at least once a year to assure its measurement
accuracy. When calibrating, please contact your nearest Sales representative at its address on the
back cover of this manual.
Press and hold the MODE key and then turn on the power switch to place the recorder in the
calibration mode. Select the subunit and module to calibrate the recorder on a module basis.
After completing the calibration, turn off the power and then turn it back on when resuming the
measurements.

CAUTION
You can use the DISPLAY mode only for a calibration adjustment. If it is
maladjusted, the recorder may become faulty. For details, please
contact your nearest Sales representative.

Calibration needs selection of:
• a subunit and module and;
• the calibration mode.
Once the subunit and module have been selected, they are no longer selected again as long as the
calibration END mode is not executed.
Calibration mode
• CAL/EXEC mode: This mode enables specified ranges to be calibrated.
• DISPLAY mode: This mode enables current calibrated values to be displayed.
• END mode: This mode enables calibrated values to be stored in the internal nonvolatile
memory and terminates the calibration mode. (If ABORT is selected, the calibrated values are
not stored in memory.)
Subunit/module selection error
The following error messages are displayed:
• The specified subunit remains disconnected. Or the power supply is not turned on.
• The specified module remains disconnected (ERROR141).
• The specified module is such that it cannot be calibrated (ERROR143).
Calibrated data error
The following error messages are displayed:
• Attempted to remove the module during calibration. Or hardware error: ERROR145
• Invalid calibrated data: ERROR144
• Attempted to set invalid numeric values in the DISPLAY mode: ERROR145

Note
When a calibrated data error appears, the error data are stored in memory.

Information on and Process in Case of Power Failure
• The DR recorder adds ¥ to the time on a printout provided upon recovery from a power failure.
It does not print the character, however, if it has been more than 12 hours since the power
failure occurred.
• The DR recorder excludes data occurring during a power failure from its reports.
• If the DR recorder recovers from a power failure after the time to make a report, it makes a
report immediately after the recovery.
• In an application where the REPORT PRINT menu item is set to on for automatic printing, the
DR recorder prints a report only immediately after it recovers from a power failure if the power
failure time is less than 12 hours and the recorder has recovered after the preset time for report
printing.
• In an application where the REPORT PRINT menu item is set to on for automatic printing, the
DR recorder prints a report at the scheduled time for report printing if a power failure time is
less than 12 hours and the recorder has recovered before the preset time for report printing.
• If a power failure time is longer than 12 hours, the DR recorder stops report making even if the
power is restored.
The recorder prints a report (for data acquired up to the power failure), however, immediately
after it recovers from the power failure.
• If a power failure time is longer than 12 hours, the DR recorder does not print a report even if
the menu item for automatic printing is set to on. In that case, you can print a report from the
FUNC menu or send data to a communication output.

Measured Data Items
For each module, a maximum of six data items can be selected from the effective voltage,
effective current, active power, apparent power, reactive power, frequency, power factor and
phase angle. The selected data items can then be assigned to channel numbers xx1 to xx6 to show
them on the display as well as record them. Restrictions apply to the combination of selectable
data items, however, depending on the method of input wiring.
Conditions of Measurement
• Measuring range for current and voltage inputs
10% of the measuring range < current and voltage inputs ≤ 100% of the measuring range
• V1 range is monitored in frequency measurement
• All measurements are done relative to the frequency on a channel for V1 and, therefore, the
results of measurements are not guaranteed if the V1 input is out of the range noted above.
• If the input apparent power falls below 10% of the span, the DR recorder cannot measure the
phase and power factor (negative overflow).
• A maximum of two scans' worth of data become invalid immediately after a change has been
made to the measuring range and/or wiring.

0.5 s*

*: The interval between data updates is fixed to one second.

Method of Input
Potential with reference to the shared voltage of the COMMON line within the same module
Types of Input
Voltage-free contact or open collector (TTL or transistor)
Measurement Modes
RATE (instantaneous count mode): Outputs the prescaled value of the count of pulses imposed
over the last one-second interval of measurement.
GATE (instantaneous turn-on time mode): Outputs the prescaled values of the contact's turn-on
(make) and turn-off (break) times (on = 1; off = 0) over the last one-second interval of
measurement.

Note
The computing function (computational expression: TLOG.PSUM (XXX)) should be used when
integrating an every-second count or turn-on time (maximum count/turn-on time: 99999999).

Input Range
0 to 6,000 pulses, or 0 to 10 pulses (if the filter is on) for voltage-free input.
Ratio of make at input: 35 to 65% at the maximum frequency (ratio of make = closed-contact
time/(closed-contact time + open-contact time) × 100)
Minimum input pulse width: 60 µs (whether the contact is closed or open)
Measuring Accuracies
As described below, under the following operating conditions:
Ambient temperature: 23 ±2°C; ambient humidity: 55 ±10% RH; power supply voltage: 90 to 250
VAC (AC power supply)/10 to 32 VDC (the subunit of a DC power supply model only); power
supply frequency: 50/60Hz within ±1% (AC power supply); warm-up time 30 minutes or more;
vibrations and others not affecting instrument operation.
Count: ±1 pulse (for integration, ±(1 scan + 1 second) at the start of measurement and ±(1 scan +
1.5 seconds) at the end of measurement)
Turn-on time: ±100-ppm accuracy for judgment of one-second-interval sampling; for integration,
±(1 second + 1 scan) at the start of measurement and ±(100 ppm of rdg. + 1.5 seconds + 1 scan) at
the end of measurement
Module-to-module error: ±(3 seconds + 1 pulse) for count and ±(200 ppm + 3 seconds) for turnon time

Note
It takes a maximum of 2 seconds for normal measured values to be output when the power is turned on,
when the measurement mode is changed or when the setting for turning on/off the filter is changed. The
DR recorder indicates a value representative of “no data” (
on the display, or 8005H for the
binary format or a faulty data value for the ASCII format in the case of output to the communication line)
until the normal measured values are output.

Filter
Removes chatter of up to 5 ms (can be turned on or off on a channel basis).
