1The

sensor generally limits the actual temperature range. Temperature accuracy specifications do not include sensor accuracy. Thermistor temperature accuracy assumes a 10kΩ sensor. Thermocouple accuracy is with internal reference junction compensation; accuracy is
improved with external reference junction compensation. Thermocouple temperature accuracies are given for external reference junction
compensation and internal reference junction compensation, respectively.
2Measurement accuracy specifications apply within the operating temperature range and assume 4-sample averaging and 4 lead wires for
PRTs. With 3-wire RTDs add 0.05Ω to the measurement accuracy plus the maximum possible difference between the resistances of the
lead wires.

3Actual

resolution can be set greater than typical resolution, but the added digits (0.0001 max.) may not be meaningful to the measurement.

3.2

Environmental Conditions
Although the instrument has been designed for optimum durability and trouble-free operation, it must be handled with care. The instrument should not be
operated in an excessively dusty, dirty, or wet environment. Maintenance and
cleaning recommendations can be found in the Maintenance section of this
manual.
For full accuracy, operate the instrument in ambient temperatures between
16–30°C (61–86°F). The battery may not charge properly at temperatures
above 30°C. Do not operate the instrument in an environment colder than 5°C
(41°F) or warmer than 40°C (104°F).
The instrument operates safely under the following conditions:
• Operating temperature range: absolute 5–40°C (41–104°F) [full accuracy
16–30°C (61–86°F)]
• Ambient relative humidity: maximum 80% for temperature <31°C, decreasing linearly to 50% at 40°C
• Pressure: 75 kPa–106 kPa

1529 Chub-E4 Thermometer Readout
User’s Guide

4.4.1

Using the Clamp-on Ferrites
Clamp-on ferrites are provided with this product for the use of improving its
electromagnetic (EM) immunity in environments of excessive EM interference.
During EMC testing we found that ferrites clamped around the probe cables
and power cord reduced the risk that EM interference affects measurements.
Therefore, we recommend that the clamp-on ferrites provided (Steward P/N
28A2025-0A2) be used on the cables of probes attached to this product, especially if it the product is used near sources of EM interference such as heavy industrial equipment.
To attach a ferrite to a probe cable, make a loop in the cable near the connector
and clamp the ferrite around half of the loop as shown in Figure 1. The ferrite
can be easily snapped open and moved to a new probe when needed.

4.5

Connect the Power Source
The 1529 draws power from either a 15-volt DC power supply (the included
AC adapter) connected to the DC input or the internal re-chargeable battery
pack. To use the AC adapter, plug it into a wall outlet of the appropriate voltage
and insert the DC plug into the DC power input of the 1529 (see Figure 3 on
page 18.)

4.6

Switch the Power On
Power is turned on and off with the power switch located on the top right corner of the back panel. To switch the power on, toggle the power switch to the
‘ON’ position. To switch power off, toggle the power switch to the ‘OFF’ position. The instrument takes a few seconds to power up, initialize, and begin normal operation. A self-test is performed displaying the channel configuration
and status of the system, calibration, GPIB, memory, and buttons. If the thermometer readout calibration has expired, the user is notified and must press the

4 Quick Start
Measure Temperature

Enter button to continue initialization. If an error message is displayed on
power up see Section 11.1, Troubleshooting.

4.7

Measure Temperature
After initialization, the temperature measurements for the configured channels
are displayed. The appropriate sensor type must be selected and coefficients entered for the measurements to be accurate (see Section 7.2.1, Edit Probe). Place
the sensors of the probe into the object(s) you want to measure. DO NOT force
the probe(s) or otherwise allow them to be bent, stressed, or overheated. Probes
can be easily damaged if misused. For further suggestions on handling the
probe and using the 1529 and probe to measure temperature accurately, see

General Operation
This section explains basic operation of the 1529 thermometer readout. Detailed operation of the 1529 is explained in Sections 7 and 8. Section 7 explains
the menu structure and the functions available in the menu structure and Section 8 explains the communications interface for operating the 1529 remotely.

6.1

Display
The 1529 display consists of two parts. The top portion of the display is used
for displaying the measurements from one to four inputs. The bottom portion of
the display is reserved for the programmable fields and field display sets. Information about the channels and measurements can be displayed in greater detail
such as min, max, spread, standard deviation, and many other functions. When
the measure period is 0.1 or 0.2 seconds (fast measurement mode), the programmable fields and field display set information are not displayed.

6.2

Changing Units
The 1529 thermometer readout is capable of displaying temperature in Celsius
(C), Fahrenheit (F), or Kelvin (K). (Displaying in units of Ω, KΩ, or mV is also
available through the PROBE menu and is channel specific.) Temperature units
are changed on all channels (not individually) by pressing the buttons on the
front panel when not in the menu structure. Press the Unit, LR, buttons to
scroll forward and backward through C, F, or K. All channels or fields that are
displaying temperature on the upper or lower display are updated to the new
units.
Channels that are set to Ω, KΩ, or mV in the PROBE menu are left unchanged
when temperature units are modified. Changing the units resets the statistical
calculations (displayed in the bottom portion of the display).

6.3

Battery
The 1529 thermometer readout has a built-in nickel-metal-hydride battery pack
that can power the instrument for about eight hours before needing to be recharged. The battery discharges more quickly when the display backlight is
used. The percent of battery charge remaining is displayed on the bottom portion of the display when the battery power is being used. The battery percentage is approximate and should only be used as a general guideline when
determining the length of charge remaining. The battery is recharged in situ
(while in place) using the AC adapter that is provided.
Plug the AC adapter into the wall outlet and connect the DC plug of the adapter
into the 1529. The battery is charged as necessary whether or not the instrument is switched on. The power control circuit inside the instrument manages
battery charging and stops charging the battery automatically when the battery
21

1529 Chub-E4 Thermometer Readout
User’s Guide

is fully charged. Only charge the battery when ambient temperature is between
16°C and 30°C (61°F and 86°F) It normally takes about three hours to fully
charge the battery. The instrument can be operated while the battery is being
charged. The charging indicator on the back panel is green when the battery is
fully charged and amber when being charged using the AC adapter.
The battery may self-discharge over several months, especially if the temperature is warm. The battery pack can be used for a minimum of 500 charge-discharge cycles before needing to be replaced. Replacement battery packs are
available from the manufacturer. The battery pack can be easily removed and
replaced in the field by following this procedure:
1.

Power the 1529 off and unplug the AC adapter from the unit.

2.

Turn the 1529 over to expose the battery compartment. Remove the battery cover hex screw. Place the screw in a safe place so it won’t get lost.
Flip open the battery cover to reach the battery pack.

3.

Remove the battery pack. Gently disconnect the battery plug connector.

4.

Attach the polarized plug of the new battery pack onto the connector.
Note: The battery plug is polarized and can only be plugged in one direction. DO NOT force it. Place the battery pack in the battery
compartment.

5.

Close the battery cover and replace the screw. Avoid pinching the battery
wires.

6.

Plug in the AC adapter and charge for a minimum of four hours for the
initial charge. Used batteries must be disposed of properly. Check your
local regulations for additional information. You may return used batteries to the manufacturer. Never dispose of batteries in fire as this may result in an explosion with the possibility of personal injury or property
damage.

When the battery charge is not at 100%, the measurement accuracy is not affected. If the power is interrupted while the instrument is logging measurements (on demand or automatically), the logged data is preserved and logging
resumes when the power is restored.

6.4

Probe Input Modules
The 1529 can be configured in three ways:
• Two RTD/thermistor input modules.
• Two thermocouple input modules.
• One RTD/thermistor and one thermocouple input module.
Each input module supports two channels. Your 1529 thermometer readout is
configured at the factory and is not field changeable. Input modules should
never be removed for any reason.

22

6 General Operation
Probe Input Modules

All possible configurations are shown in Figure 3 on page 18.

6.4.1

Connecting a PRT or Thermistor Probe
PRT and thermistor probes are attached to the resistance input module via Hart
Scientific mini-DWF connectors. These patented connectors accept bare wire,
spade, or mini banana plug terminations. The connectors are color coded for
ease in connecting lead-wires.
When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as
stated in the specifications. Compensation is made for 3-wire PRTs, but the difference in lead resistance affects the measurement accuracy. The 1529 thermometer readout is unable to compensate for 2-wire lead resistance.
Attach the lead-wires of the probes as shown in Figure 5 on page 24. The top
termainals sense current and the bottom terminals sense potential.

6.4.2

Connecting a Thermocouple
The 1529 thermocouple input module accepts both standard and sub-miniature
size thermocouple connectors. The connection is made with the positive terminal on the right and the negative terminal on the left. You must use a connector
that matches the thermocouple type for the internal RJC to be accurate. For example, if you are using a type K thermocouple you must also use a type K connector, which is made from the same type of metal. For best results, wait two
minutes before measuring after inserting the thermocouple connector into the
input module.

DC Power Source

6.5

DC Power Source
Caution: For CE compliance and for performance, use only the AC
adapter shipped with the instrument by Hart Scientific. If the AC adapter
needs to be replaced, contact a Hart Authorized Service Center (see Section 1.3).
The DC power source provides power to charge the battery. It can also be used
to power the 1529 while the battery is being charged. The AC adapter provided
with the 1529 is intended for these purposes. The DC power source plugs into
the DC power input on the back panel of the instrument. The AC adapter has
circuits with high voltages inside that could present danger of electric shock or
fire if exposed. If the AC adapter is damaged in any way or becomes hot, discontinue use immediately, disconnect the adapter from any AC supply, and replace the adapter. Do not attempt to open, repair, or continue using a damaged
or defective AC adapter.

6.6

Power On Self-Test
When power is turned on, the 1529 performs a self-test checking the system, all
channels, calibration, GPIB, memory, and buttons. If an error occurs, an error
message is displayed. See Section 11.1, Troubleshooting for additional information on error messages.

6.7

Display Backlight and Contrast
The display backlight is adjustable for use in varying lighting conditions. The
four backlight modes are accessible in the CHANNEL menu DISPLAY OPTIONS function. If the display appears faded, dark, or blank, adjust the contrast (off, low, medium, high) using the front panel contrast buttons.

6.8

Taking Measurements
The procedure for configuring the 1529 thermometer readout to take measurements on a particular input channel requires the following: (1) connecting the
sensor to the appropriate input channel , (2) enabling the channel, and (3) selecting the conversion type and probe characterization values.

6.8.1

Connecting the Sensor
Connect the sensor to the RTD/Thermistor channel(s) or thermocouple channel(s) that you want to measure. Refer to Section 7.4, Probe Input Modules, for
additional information.

25

1529 Chub-E4 Thermometer Readout
User’s Guide

6.8.2

Enabling the Channel
Channels are set first by selecting either simultaneous or scan mode in the
CHANNEL menu CHANNEL MODE function. Simultaneous mode shows one
to four channels in the upper display simultaneously. Scan mode shows one
channel at a time (in large digit format) scanning through one to four channels
depending on the channels that are enabled. After the mode has been selected,
use the CHANNEL menu ENABLE CHANNEL function, to select the channel
to be displayed. Any channel set to ‘Off’ is not displayed. See Sections 7.1.3,
Channel Mode, and 7.1.2, Enable Channel, for more information.

6.8.3

Selecting Conversion Type and Probe Characterization
Before the 1529 can accurately measure temperature, it must be configured to
calculate temperature from the resistance or voltage of the sensor. There are
many temperature conversion algorithms available and the one to use depends
on the type of sensor and its calibration. Many conversion algorithms use coefficients that characterize the sensor. Coefficients are determined when the sensor is calibrated. SPRTs and RTDs often use the ITS-90 algorithms and are
provided with ITS-90 characterization coefficients. Thermistors often use the
Steinhart-Hart algorithms and coefficients. Thermocouples use standard tables
or equations depending on its type. For additional information on conversion
types, see Section 7.2, Probe Menu.
The conversion type and characterization coefficients for a sensor are specified
using the PROBE menu EDIT PROBE function (see Section 7.2.1).

6.9

Fast Measurement Mode
Fast Measurement Mode applies to measure periods of 0.1, 0.2, or 0.5 seconds.
This mode allows measurements to be displayed or logged quickly.
Normally, when each measurement is made a self-calibration of the measurement circuit is performed simultaneously during the measurement process to
offset errors from component drift and spurious EMFs. For measure periods of
0.1, 0.2, and 0.5 seconds, the fast measurement rate is achieved by foregoing
the self-calibration. The drawback to this Fast Measurement Mode is the accuracy of the measurement may be poor and subject to drift. Accuracy can be
temporarily improved using the AUTO-CAL function that appears in the
CHANNEL menu when in this Fast Measurement Mode. The AUTO-CAL
function causes the instrument to perform a single self-calibration of the measurement circuit then resume fast measuring (without automatic
self-calibration).
See Section 8.1.1 for detailed information on using the Fast Measurement
Mode.

Data Logging

6.10

Data Logging
Data can be logged either on demand or automatically at a user-selected interval. When data is logged, readings are stored to the instrument's memory and
assigned a label for easy recall and organization of data. Up to 100-demand log
and 8,160 auto log readings can be stored. When data is being logged, the left
bottom corner of the main display shows a strip-recorder indicator.

ITS-90 Conversion
The ITS-90 conversion is for PRTs calibrated and characterized using the International Temperature Scale of 1990 equations. The parameters that appear
when ITS-90 is selected are RTPW, A4, B4, A, B, C, and D. These should be
set with the corresponding values that appear on the calibration certificate for
the PRT. The parameter RTPW takes the triple point of water resistance from
the certificate. The parameters A, B, C, and D take the an, bn, cn, and d coefficients from the certificate, where n is a number from 6 to 11. Parameters A4
and B4 take the a4 and b4 coefficients on the certificate. Any ITS-90 parameter
of the 1529 that does not have a corresponding coefficient on the PRT certificate must be set to 0.
When the ITS-90 conversion type is selected, the RANGE, WIRES, and coefficients are displayed on the right portion of the bottom of the display. The UD
buttons are used to scroll through the coefficients. Use the Enter button to edit
and to save the new settings. Use the LR buttons to change each digit of the
settings. Press and hold the Exit button to cancel to the main display or press

The RANGE parameter is used to select the appropriate resistance range. For
25 ohm and 100 ohm PRTs select 100 ohms and for 1000 ohm PRTs select 10K
ohms.
The WIRES parameter sets the appropriate number of lead wires from the sensor. This parameter can be set to 2-, 3-, or 4-wires. See Figure 5 on page 24 for

Thermistor T(R) Conversion [THERM-T]
The following Steinhart-Hart equation is used for the thermistor T(R)
conversion:
T(r )[ K ] = [ A0 + A1lnr + A2 ln 2 r + A3ln3r ]−1

The user-defined parameters for the thermistor T(R) conversion are A0 (A0)
through A3 (A3) as shown on a typical Hart Scientific thermistor calibration report. If A2 is not used, as is the case with some calibrations, A2 should be set to
0.0.
Note: Thermistor coefficients stated on the thermistor calibration report may be
labeled differently. The best way to identify the coefficients to use with this
type is to match the equation above with the equation given on the calibration
report. Also, recognize that the coefficients for this equation generally have
negative exponents, e.g. A3: 1.39456E-07.

7.2.1.10

Standard Thermocouple Conversions
Standard thermocouple conversions include types B, E, J, K, N, R, S, T, and
Au-Pt. Voltage is converted to temperature using standard reference functions.
(For additional information consult the publication NIST Monograph 175.)
You can specify internal or external reference junction compensation (RJC)
with the RJC parameter. (See Table 9 on page 129.) With internal RJC, the temperature of the thermocouple cold junction is measured automatically and used
to calculate the absolute temperature of the thermocouple. With external RJC, a
reference junction at a known fixed temperature is used and the value of this
fixed temperature reference must be entered in the RJT parameter and is used
to calculate the absolute temperature of the thermocouple.
Conversions for each of the thermocouple types accept functional calibration
data. This can be used to improve the measurement accuracy. The parameter,
Tn, is the temperature of the point in degrees Celsius. The parameter, ADJn, is
the temperature deviation from the reference function at the point in degrees
Celsius. The temperature measurement is adjusted by this amount when measuring at this temperature. A polynomial interpolation function is used for measurements between calibration points. If calibration data is not available or is
not to be used, the ADJn parameters should all be set to 0.0. This causes the
temperature to be calculated according to the standard reference functions.

7.2.1.11

Thermocouple Polynomial Conversion
The thermocouple polynomial conversion allows calculation of temperature by
polynomial conversion.
When the Thermocouple Polynomial conversion type is selected, the coefficients are displayed on the right portion of the bottom of the display. Use the
UD buttons to scroll through the coefficients. Use the Enter button to edit
and save the new setting. Press and hold the Exit button to cancel to the main
display or press the EXIT button to cancel and to move to the next parameter.
On the last parameter, press the Exit button to exit to the menu.
The following equation is used for the thermocouple polynomial conversion:
6

t( E [ mV])[ °C ] = ∑ C i E i
i=0

The user-defined parameters for the thermocouple polynomial conversion are
the coefficients c0 (C0) through c6 (C6). The user can specify internal or external reference junction compensation (RJC; see Table 9 on page 129). If external
RJC is selected, the user enters the temperature of the RJC reference in the reference junction temperature (RJT) parameter.
The output of the thermocouple, in millivolts, at 25°C with the reference junction at 0°C, is mV (25°C). For example, for a type K thermocouple, mV(25°C)
is 1.0002.

Auto Log
The AUTO LOG function allows measurements to be logged automatically in
user-selectable intervals. Readings are stored to the instrument's memory and
assigned a label for easy recall and organization of data. The instruments memory can store up to 8,160 auto log readings.
Auto log values are stored exactly as they appear on the upper portion of the
display. The resolution, units, and the channels displayed should be set up prior
to auto logging in order to ensure proper storage of data. All displayed channels are stored during an auto log session. If the upper portion of the display is
changed while data is being auto logged, the data collected is modified from
the time the display was changed. For example, if a channel is disabled while
auto logging, that channel stops being stored from the time it was disabled.
When this function is selected, the bottom portion of the display shows the

The LOG PER parameter is for selecting the interval between measurements.
You may select between 0.1, 0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10,
and 30 minutes or 1 hour. The LOG PER must be set to a value less than or
equal to the measurement period. The 1529 will not log readings faster than the
measurement period. The measurement period is set in the MEASURE PERIOD function of the CHANNEL menu and is the rate at which readings are
taken.
If the log period is set to a value less than the measure period the following
message is displayed in the lower portion of the display.
DATA WILL BE LOGGED NO FASTER THAN
THE MEASURE PERIOD (X SEC ).
Press ENTER to continue…
The X in the message is the current measurement period. After the Enter button is pressed, the measurements are logged at the current measure period.
The COUNT parameter is for selecting the total number of readings to log. The
default is 8,160, which is the maximum number of readings that can be logged.
If the count is set to 10 and two channels are displayed on the screen at the time
logging starts, five readings from each channel are logged for a total of 10 readings. The auto log automatically stops after the number of readings selected is
reached or when the user stops the log manually.

7.5.1.1

Serial
When the SERIAL option is selected, the parameters for the serial port are displayed on the bottom portion of the display. These parameters are: BAUD, SER
PER, LF, PRINT, and ECHO.
The BAUD parameter allows the user to select the baud rate for communications on this port. The user may choose between 1200, 2400, 4800, 9600, and
19200. The default baud rate is 9600.
The SER PER parameter allows the user to select the interval at which measurements are transmitted over the serial port. The user may choose between
0.1, 0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10, and 30 minutes, and 1
hour.
The LF parameter allows the user to specify whether a linefeed character
(ASCII 0A hex or 10 decimal) is appended to the end of each line transmitted
over the serial port. Selecting ON sends both a carriage return (ASCII 00 hex or
13 decimal) and a linefeed. Selecting OFF sends only a carriage return.
The PRINT parameter allows the user to enable printing measurements over the
serial port. Selecting ON enables printing and selecting OFF disables printing.
With slower MEA PER (see Section 7.1.1) and SER PER rates of 1 second or
more, measurements are printed with the channel number, measured value,
unit, time, and date, all separated with spaces. With faster rates, less than 1
second, only the measured value is printed.
71

1529 Chub-E4 Thermometer Readout
User’s Guide

The ECHO parameter allows the user to set the echo (duplex) mode. Selecting
ON enables echoing so that all characters received on the serial port are echoed
back over the serial port. This mode is useful when using terminal emulation
software on a computer to communicate with the instrument. Selecting OFF
disables echoing. This mode is commonly used when using control software on
the computer.

PRINT.
The MODE parameter allows the user to select the protocol used by the IR port
to transmit and receive data. The user may choose between OFF, HP-PR,
COMM, and IRDA.
The OFF option turns the IR port off.
The HP-PR option allows the user to print a new measurement to an
HP-IR calculator printer.
The COMM option allows the user to transmit data over the IR port at
9600 baud in simple ASCII format.
The IRDA option allows the user to print logged data to an IrDA compatible printer (such as an HP LaserJet 2100). Automatic real time printing is
not possible with the IrDA mode..
The IR PER parameter allows the user to select the interval at which measurements are transmitted over the serial port. The user may choose between 0.1,
0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10, and 30 minutes, and 1 hour.
The IR PER can not be set to less than 10 seconds if the MODE is set to
HP-PR.
The PRINT parameter allows the user to enable printing measurements over the
IR port. Selecting ON enables printing and selecting OFF disables printing.

8 Digital Communications Interface
Overview

8.1

Digital Communications Interface
Overview
The communication feature allows an external device, such as a computer, to
communicate with the 1529 to obtain measurement data and control operating
conditions. Communication is accomplished by issuing commands to the 1529
through RS-232, IR, or IEEE-488 communication ports.

8.2

Communications
The thermometer readout is equipped with an RS-232 serial interface, an infrared window, and optionally a GPIB port. The serial interface allows communications up to distances of approximately 50 feet. The IR interface allows
communications up to distances of 1 foot. The serial interface, infrared window, and GPIB port allow the user to access the functions, parameters, and settings discussed in Section 7, Menu Functions.

8.2.1

Serial Wiring
The serial communications cable attaches to the
thermometer readout
through the DB-9 connector at the back of the instrument. Figure 49 shows
the pin-out of this connector and suggested cable
wiring. This type of cable
is typically referred to as a
“null modem” cable. To
eliminate noise, the serial
cable should be shielded
with low resistance between the connector
(DB9) and the shield.
The serial period, baud
rate, linefeed, and echo
are programmable. Refer
to Section 7.5.1.1, Serial
Port, for instructions on
accessing and setting
these parameters.

Figure 49 Serial Cable Wiring

79

1529 Chub-E4 Thermometer Readout
User’s Guide

All commands sent to the 1529 through the serial interface must be terminated
with a carriage return or linefeed character.

8.2.2

GPIB Communications
The GPIB interface allows the Model 1529 to be connected to an IEEE-488 bus
along with other instruments. A system controller can remotely control the operation of the Model 1529 and read measurements.

8.2.2.1

Capability
The Model 1529 GPIB interface conforms to standard IEEE-488.2, 1992. Its
capabilities are identified as SH1, AH1, T6, L4, SR1, DC1, and E2. The interface has the capabilities of talk, listen, serial poll, and device clear. There is no
capability for talk-only, listen-only, extended talk or listen, parallel poll, remote-local control, or trigger nor can it act as a controller. The IEEE-488 commands GET, GTL, LLO, and REN are accepted without error but ignored.

8.2.2.2

Connection
The IEEE-488 port is located on the back of the 1529. Use a standard
IEEE-488 cable to connect to your GPIB controller. A shielded cable should be
used to prevent EM emission.

8.2.2.3

Device Setup
The Model 1529 system must be set up to respond to the controller address.
Refer to Section 7.5.1.3, GPIB, for setting address and other parameters for the
IEEE-488 port.

8.3
8.3.1

Interface Commands
Command Summary
An alphabetical listing of the commands implemented by the 1529 are shown
in Table 3 starting on page 81. These commands can be used with either serial,
IR, or IEEE-488 communications ports.

Command Syntax
The 1529 accepts commands that set parameters, execute functions or respond
with requested data. These commands are in the form of strings of ASCII-encoded characters. As far as possible, the 1529 conforms to IEEE-488.2, 1992
and SCPI-1994. One notable exception is that compound commands are not allowed as explained below.

85

1529 Chub-E4 Thermometer Readout
User’s Guide

Commands consist of a command header and, if necessary, parameter data. All
commands must be terminated with either a carriage return (ASCII 0D hex or
13 decimal) or new line character (ASCII 0A hex or 10 decimal).
Command headers consist of one or more mnemonics separated by colons (:).
Mnemonics may use letter characters, the underscore character (_), and possibly numeric digits as well. Commands are not case sensitive. Mnemonics often
have alternate forms. Most mnemonics have a long form that is more readable
and a short form consisting of three or four characters that is more efficient.
A mnemonic may end with a numeric suffix that specifies one of a set of independent function blocks such as input channel data paths. If a numeric suffix is
omitted when a particular block must be specified, an error is generated
(“Header suffix out of range”).
Query commands are commands that request data in response. Query commands have a question mark (?) immediately following the command header.
Responses to query commands are generated immediately and placed in the
output buffer. Responses are then transmitted automatically over the RS-232 or
IR ports. When using the IEEE-488 interface, responses remain in the output
buffer until read or until another command is received or the power is turned
off. Responses are lost if not read before the next command is received. Each
input buffer holds 128 characters and each output buffer holds 256 characters.
Some commands require parameter data to specify values for one or more parameters. The command header is separated from the parameter data by a space
(ASCII 20 hex or 32 decimal). Multiple parameters are separated by a comma
(,).
The 1529 does not allow compound commands (multiple commands per line
separated with semicolons). All commands are sequential. The execution of
each command is completed before subsequent commands are processed.

8.4

Commands
Table 3, Alphabetical List of Commands in Section 8.3.1, lists the commands
in alphabetical order. In this section the commands are arranged into the following groups:
Measurement Commands – commands for reading measurement data.
Measurement Control Commands – commands for the timing and action of
the measurement process.
Channel Commands – commands for selecting channels.
Probe Commands – commands for temperature conversion and probe
characterization.
Calibration Coefficient Commands – commands for channel calibration
coefficients.
Display Commands – commands for display options and settings.

86

8 Digital Communications Interface

Logging Commands – commands for automatic and demand logging.
System Commands – commands for general system configuration parameters.
Communication Interface Commands – commands for controlling the interface configuration(serial port, IR, and IEEE).
Date and Time Commands – commands for setting the date, time and the date

• Numeric data, specified by the mnemonic, , uses ASCII characters
to represent numbers. Numbers may contain a plus or minus (‘+’ or ‘-’)
sign, decimal point (‘.’), and exponent (‘E’ or ‘e’) with its sign. If a fractional component is received when only an integer is required, the number
is rounded to the nearest integer without any resulting error message. The
mnemonics DEF, MIN, and MAX are often acceptable for the default,
minimum, and maximum value respectively. Unit suffixes, such as V or
OHM, can be appended to numeric parameters and are accepted without
error but ignored.
• Unrecognized commands or commands with incorrect syntax or invalid
parameters generate error messages in the error queue.
• Upper case letters designate syntax that is required when issuing the command. Lower case letters are optional and may be omitted.
• <> indicates a required parameter.
• [] indicates optional parameters.
• () indicates a group of parameters that must be used together.
• For query commands, specifying the MIN, MAX, or DEF parameter
causes the instrument to respond with the minimum, maximum, or default

Calibration
Each channel of the 1529 is calibrated independently of the other channels and
has its own set of calibration parameters. The 1529 should be calibrated at regular intervals to ensure that it continues to measure with proper accuracy. Calibration should only be done by qualified, authorized personnel. When the 1529
is recalibrated, all four channels are calibrated each calibration cycle. The calibration label indicates the calibration date and recalibration due date for the entire instrument.

PRT Calibration Parameters
Three adjustable parameters are used for calibration: C0, C100, and C400. The
C0 parameter directly affects the measurement at 0Ω. It has negligible effect at
100Ω but significant affect at higher resistances. The C100 parameter directly
affects the measurement at 100Ω. It has negligible effect at 0Ω and proportionately greater effect the higher the resistance. The C400 parameter directly affects the measurement at 400. It has negligible effect at 0Ω and 100Ω with
greater effect as the resistance increases. Each of the parameters has positive effect at their primary resistances: increasing the value of the parameter increases
the measured resistance. The theoretically normal value for each is 0.

131

1529 Chub-E4 Thermometer Readout
User’s Guide

The calibration parameters C0, C100, and C400 can be adjusted to optimize the
accuracy. These password-protected parameters are accessed from the CALIBRATION function of the SYSTEM menu.

9.1.2

PRT Calibration Procedure
Calibration requires adjustment of the C0, C100, and C400 parameters at three
specific input resistances. If the resistances used are approximately 0Ω, 100Ω
and 400Ω respectively the adjustments are independent and the procedure is
simple. The order in which the adjustments are performed is important. The adjustment of the C400 parameter must be done last as the adjustments of C0 and
C100 affect the measurement at 400Ω but C400 does not affect the measurements at 0Ω or 100Ω. Each channel must be calibrated. Set the conversion type
to RES to display resistance (see Section 7.2.1.5) and the RANGE parameter to
100Ω. The calibration should be performed with a four-wire connection and
with the probe wiring parameter set to four-wire (see Section 6.4, Connecting
the Probe). The accuracy required of the resistance standards is 1/4 of the instrument accuracy; that is ±0.000125Ω at 0Ω, ±0.0006Ω ( 6 ppm) at 100Ω, and
±0.0024Ω (6 ppm) at 400Ω. The recommended procedure is as follows:
1.

Connect a 0Ω resistor to the input and measure its resistance. If a shorting wire is used the wire should run from the C2 terminal to the C1 terminal to the P1 terminal to the P2 terminal (See Figure 50). Note the
average error in the measurement. Adjust the C0 parameter by subtracting the measured error. For example, if the input is exactly 0.0000 and
the readout shows –0.0011, adjust the C0 parameter by adding 0.0011.

Connect a 100Ω resistor (6 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C100
parameter by subtracting the measured error. For example, if the input is
exactly 100.0000Ω and the readout shows 100.0295Ω, adjust the C100
parameter by subtracting 0.0295.

9.1.3

3.

Connect a 400Ω resistor (6 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C400
parameter by subtracting the measured error. For example, if the input is
exactly 400.0000Ω and the readout shows 399.9913Ω, adjust the C400
parameter by adding 0.0087.

4.

Record the date in the DATE parameter and set the DUE parameter to
the desired calibration interval.

5.

Verify the accuracy at 0Ω, 25Ω or 50Ω, 100Ω, 200Ω, and 400Ω on each
channel.

Thermistor Calibration Parameters
Three adjustable parameters are used for calibration: C0K, C10K, and C100K.
The C0K directly affects the measurement at 0Ω. It has negligible effect at 10
kΩ but significant affect at higher resistances. The C10K directly affects the
measurement at 10 kΩ. It has negligible effect at 0Ω and proportionately
greater effect the higher the resistance. The C100K directly affects the measurement at 100 kΩ. It has negligible effect at 0Ω and 10 kΩ with greater effect
as the resistance increases. Each of the parameters has positive effect at their
primary resistances: increasing the value of the parameter increases the measured resistance. The theoretically normal value for each is 0.
The calibration parameters C0K, C10K, and C100K can be adjusted to optimize the accuracy. These parameters are accessed from the CALIBRATION
function of SYSTEM menu.

9.1.4

Thermistor Calibration Procedure
Calibration requires adjustment of the C0K, C10K, and C100K parameters at
three specific input resistances. If the resistances used are approximately 0Ω,
10 kΩ and 100 kΩ respectively the adjustments are independent and the procedure is simple. The order in which the adjustments are performed is important.
The adjustment of the C100K parameter must be done last as the adjustments
of C0K and C10K affect the measurement at 100 kΩ but C100K does not affect
the measurements at 0Ω or 10 kΩ. Each channel must be calibrated. Set the
conversion type to RES to display resistance and set the RANGE parameter to
10KΩ. The accuracy required of the resistance standards is 1/4 of the instrument accuracy; that is 0.12Ω at 0Ω, 0.25Ω (25 ppm) at 10 kΩ, and 2.5Ω (25
ppm) at 100 kΩ. The recommended procedure is as follows:
1.

Connect a 0Ω resistor to the input and measure its resistance. If a shorting wire is used the wire should run from the C2 terminal to the C1 terminal to the P1 terminal to the P2 terminal (See Figure 50 on page 132).
Note the average error in the measurement. Adjust the C0K parameter by
subtracting the measured error. For example, if the input is exactly 0.0Ω
and the readout shows –0.11Ω, adjust the C0K parameter by adding
0.11.

2.

Connect a 10 kΩ resistor (25 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C10K
parameter by subtracting the measured error. For example, if the input is
exactly 10.00000 kΩ and the readout shows 10.00295 kΩ, adjust the
C10K parameter by subtracting 2.95.

3.

Connect a 100 kΩ resistor (25 ppm accuracy) to the input and measure
its resistance. Note the average error in the measurement. Adjust the
C100K parameter by subtracting the measured error. For example, if the
input is exactly 100.0000 kΩ and the readout shows 99.9913 kΩ, adjust
the C100K parameter by adding 8.7.

4.

Record the date in the DATE parameter and set the DUE parameter to
the desired calibration interval.

5.

Verify the accuracy at 0Ω, 4kΩ, 10kΩ, 40kΩ, 100kΩ, and 500kΩ on
each channel.

9.2.2

Calibration Procedure
Calibration of each channel is performed in two steps. First the voltage measurement is calibrated then the internal RJC is calibrated. The equipment required are a programmable voltage source, a precision voltmeter with an
accuracy of 10 ppm or better, a thermocouple (preferably type E), and a temperature source between 0 and 30°C. The combined accuracy of the reference
thermocouple and temperature source must be 0.06°C or better between the reference temperature and ambient temperature. At each step during the calibration procedure the readings should be allowed to settle for at least two minutes
before recording the measurement. Also, the 1529 should be allowed to warm
up for at least one hour after power up prior to calibration. The recommended
procedure is as follows:
1.

Connect the voltage source to the thermocouple channel, set it for 0 mV,
and measure the voltage with the 1529 and the voltmeter simultaneously.
Adjust the C0 parameter by subtracting the measured error. For example,
if the 1529 measures –0.0006 mV, adjust the C0 parameter by adding
0.0006. If it was previously 0.0000 it should now be 0.0006.

2.

Set the voltage source to 100 mV and measure the voltage with the 1529
and the voltmeter simultaneously. Adjust the C100 parameter by subtracting the measured error. For example, if the input is exactly 100.0000
mV and the 1529 shows 100.2953 mV, the C100 parameter should be adjusted by subtracting 0.2953. If it was previously 0.0000 it should now
be –0.2953.

3.

Verify the voltage accuracy at 0, 50, and 100 mV. The accuracy must be
within the short-term voltage accuracy given in the specifications.

4.

Connect the calibrated thermocouple to the thermocouple channel and
insert the thermocouple into the temperature source. Measure the temperature with the 1529 (be sure to program the channel with the correct
thermocouple type). Adjust the CRJ parameter by subtracting the mea-

User’s Guide

sured error. For example, if the thermocouple temperature is actually
0.0°C but the 1529 reads 0.184°C, the CRJ parameter should be adjusted
by subtracting 0.184. If it was previously 0.000 it should now be –0.184.

136

6.

Record the date with the DATE parameter. Set the DUE date to the desired calibration interval.

7.

Repeat the procedure for any other thermocouple channels.

10 Maintenance

Maintenance
• The calibration instrument has been designed with the utmost care. Ease
of operation and simplicity of maintenance have been a central theme in
the product development. Therefore, with proper care the instrument
should require very little maintenance. Avoid operating the instrument in
oily, wet, dirty, or dusty environments.
• If the outside of the instrument becomes soiled, it may be wiped clean
with a damp cloth and mild detergent. Do not use harsh chemicals on the
surface, which may damage the LCD or the plastic front panel.
• If a hazardous material is spilt on or inside the equipment, the user is responsible for taking the appropriate decontamination steps as outlined by
the national safety council with respect to the material.
• Before using any cleaning or decontamination method except those recommended by Hart, users should check with a Hart Authorized Service
Center (see Section 1.3) to be sure that the proposed method will not
damage the equipment.
• If the AC adapter becomes damaged, have it replaced immediately. Never
disassemble the AC adapter or attempt to repair it.
• If the instrument is used in a manner not in accordance with the equipment design, the operation of the thermometer readout may be impaired
or safety hazards may arise.
• Periodic calibration of the instrument at regular intervals is required to ensure that it continues to measure with proper accuracy. Calibration should
only be performed by qualified authorized personnel.

Troubleshooting
In case you run into difficulty while operating the 1529 system, this section
provides some suggestions that may help you solve the problem. Below are
several situations that may arise followed by possible causes and suggested actions you might take.

11.1

Troubleshooting
The following table lists possible error messages, their causes, and suggested
actions.

Problem

Solution

Incorrect temperature reading

While attempting to measure temperature, the display shows an incorrect value or no value at all
( . . . . . . . . . ).
• If the temperature readings seem to be incorrect you should first check to see if the
resistance, or voltage in the case of thermocouples, is being measured correctly.
Set up the display to show the resistance or voltage for the channel.
• If the resistance or voltage is incorrect refer to the next subsection for troubleshooting incorrect resistance or voltage readings.
• If the resistance or voltage is being measured correctly but the displayed temperature value is incorrect consider the following possibilities:
One or more coefficients are incorrect. This is a common mistake. While entering coefficients
it is easy to miss a digit or sign. Check all the values carefully using the EDIT PROBE function
(see Section 7.2.1) comparing them with the values on the calibration certificate for the probe.
Use the TEST PROBE function to test the coefficients (see Section 7.2.1.10, Standard Thermocouple Conversions).
The selected conversion type is incorrect. Check to make sure the correct conversion type is
selected. In the case of thermocouples, make sure you have selected the correct type. You
should also make sure that you have selected the proper reference junction compensation (RJC)
made for your application (see Section 7.2.1.10, Standard Thermocouple Conversions). You
can use the TEST PROBE function to test the temperature conversion calculation.
The measurement is out of range. The 1529 may not be able to calculate temperature accurately if the resistance or voltage is outside the valid range. The measured resistance or voltage
may be too low or too high if the actual temperature is too low or too high or if there is a problem
with the sensor.
• The measure period may be set to a long interval. Check the measure period setting.

Problem

Solution

Incorrect resistance or voltage
reading

While attempting to measure resistance or voltage, the display shows an incorrect value or no value at
all
(. . . . . . . . . . ).
Consider the following possibilities:
Poor or incorrect connection of the probe. A common mistake is to connect the wires of the probe
to the wrong terminals. Check the wiring carefully, especially when using a four-wire PRT (see Section
6.4.1). Make sure the lead wires are fastened down tightly.
Open, shorted, or damaged sensor or lead wires. In the case of resistance sensors check the resistance across the sensor using a hand-held DMM. Also check the resistance between common pairs of
leads. Check to make sure there is no conductivity between any of the leads and the probe sheath.
Use a good-quality sensor to avoid errors caused by drift, hysteresis, or insulation leakage. In the case
of thermocouples, use a hand-held DMM to check its voltage.
Improper setting for three or four-wire probe. Make sure the correct wiring type is selected Selecting three-wire input while using four-wire probes may cause errors of 0.01 to 0.1 ohms. Selecting
four-wire input while using three-wire probes will result in erratic or out-of-range readings (see Section
7.2.1.1).
Electrical interference. Intense radio-frequency radiation near the 1529 or probes can induce noise
into the measurement circuits resulting in erratic readings. The 1529 is intended to operate in a laboratory environment with limited radio-frequency noise. If interference seems to be a problem you might
try eliminating the source of interference or moving the 1529 to a different location. A well-grounded,
shielded cable should be used for the probe leads.
Stem conduction error. The problem may be that the actual temperature of the sensor is not what
you expect. This is often the result of stem conduction where heat flowing through the stem of the
probe to ambient affects the temperature of the probe. It is very important that probes be inserted to an
adequate depth into the material being measured. Measuring temperature using a surface sensor can
be especially difficult as the sensor is directly exposed to ambient.
Wrong calibration parameters. The problem may be that the calibration parameters for the 1529 are
invalid. Check the parameters currently stored in the unit against those listed on the 1529 Report of
Calibration.

Blank screen

The screen lights up when the 1529 is switched on but the screen appears blank. This problem
can be caused by improper adjustment of the contrast. After the power is switched on allow the 1529
at least one minute to complete its self-test and power on sequence. Then, try to adjust the contrast
using the contrast buttons.

Error message at power up

The 1529 reports an error during the power up self-test. On power up the 1529 performs a series of
self-tests to check the operation of all its components and each of the modules. The results of the
self-tests are reported on the screen. Normally, all tests report ‘OK’. Below is a table of error messages
and recommended actions to correct the error. Often these errors can be corrected by completing the
actions listed. A failure of one or more component causes error messages to be reported. Component
failures generally require a qualified factory technician to replace the faulty component. Contact a Hart
Authorized Service Center (see Section 1.3).

Temperature not
updating

The 1529 measure period may be set to a long interval. Check the measure period.

Frequently Asked Questions

The instrument was designed specifically as a test and measuring device. Compliance to the EMC directive is through IEC 61326-1 Electrical equipment for
measurement, control and laboratory use – EMC requirements (1998).
As noted in the IEC 61326-1, the instrument can have varying configurations.
The instrument was tested in a typical configuration with shielded, grounded
probe and RS-232 cables. Emissions may, in non-typical applications, exceed
the levels required by the standard. It is not practical to test all configurations,
as the manufacturer has no control over the probes the user may connect to the
instrument.
11.4.1.1

Immunity Testing
The instrument was tested to the requirements for industrial locations. This allows the instrument to be used in all types of locations from the laboratory to
the factory floor. Criterion B was used for Radiated RF (IEC 61000-4-3) and
Conducted RF (IEC 61000-4-6). Therefore, the operation of the instrument
may be affected by excessive electromagnetic interference and the instrument
may not perform within the normal specification limits in such an environment.
Criterion C was used for Electrostatic Discharge (ESD, IEC 61000-4-2) and
Electric Fast Transit (EFT, Burst, IEC 61000-4-4). If the instrument is subjected to EFT conditions at 2kV, the instrument may require the user to cycle
the power to return to normal operation.

3.

How long does the battery take to fully charge? About 3 hours from
fully discharged.

143

1529 Chub-E4 Thermometer Readout
User’s Guide

4.

How long does the battery last from full charge? About 8 hours from
full charge with the backlight off.

5.

How do I know when the battery is at full charge? The charging indicator LED located on the back panel displays amber while charging and
then turns green when the batteries are fully charged (only when the AC
adapter is connected). The front panel indicator at the bottom right
shows when the batteries are in use and their approximate charge state.

6.

How does the backlight affect the battery life? With the backlight on low
the battery life is reduced by 25%, medium by 30%, and high by 40%.

7.

Do I have to let the battery fully discharge before charging? No, the batteries do not need to be fully discharged before recharging. You may recharge them at any time.

8.

Is it recommended that I allow the battery pack to fully discharge occasionally? In order to maintain the charge/discharge characteristics of the
battery, Hart recommends that you allow the battery to discharge completely once a month. You do this by allowing the Model 1529 to operate
on battery power until it shuts down on its own.

9.

If I allow the battery pack to fully discharge, what happens to the calibration parameters stored in the Model 1529? Parameters used by the Model
1529 are stored in non-volatile RAM (NVRAM). This IC stores the parameters even when power is not applied.

10. How many recharge cycles is the battery good for? Approximately 500.
11. What happens to my measurement accuracy when the battery is low?
The Model 1529 does not display temperature when there is not sufficient power to make a correct measurement.
12. If I am using the autolog and the battery runs out will I lose my data?
No, you won’t lose any data. The Model 1529 simply stops logging
data. When the AC adapter is plugged in, the data logging continues.
13. How do I dispose of the batteries used in the Model 1529? Disposal
guidelines can be found by consulting your local governing authority.
14. If the AC adapter is plugged in and I have the unit turned on, is the battery still charging? Yes, the Model 1529 charges while in use without affecting the charging time or its performance.
15. If I am using the Model 1529 with AC power and a power outage occurs,
will the batteries automatically take over? Yes, when AC power is removed from the Model 1529 for any reason, the batteries automatically
supply back up power without risk of losing any data.

11.5.2

Input

Can I swap out measurement boards in the field? No, the measurement
boards were not designed to be exchanged in the field.

11 Troubleshooting
Frequently Asked Questions

11.5.3

2.

What are the implications of the fast measurement mode in terms of accuracy? Accuracy is reduced when using the Model 1529 in fast measurement mode. Refer to Section 8.1.1 for a better description of the fast
measurement mode and its limitations.

3.

Why can I only see one channel in the fast measurement mode? Because
of the time required to make a measurement and update the display, there
is not enough time to display more than one channel when in the fast
measurement mode.

4.

Do I have to reprogram the Model 1529 each time I swap out a probe?
In addition to the four main channels, there are nine memory locations
available to store probe coefficients. If the new probe’s information has
been programmed into one of these locations, you can copy it to the
channel to which it is connected.

5.

How does the moving average affect the data that is logged? The data
collected by the Model 1529 is stored as it appears on the display. If you
set the Model 1529 to average the measurements, the data it logs reflects
the moving average setting.

6.

How many probe coefficients can I store? Thirteen. Four sets in the
main channels and nine sets in memory locations.

7.

Are the readings really simultaneous in the simultaneous mode? Yes.
There are four measurement circuits that collect the raw data simultaneously. The raw data is then converted to its corresponding temperature
in sequence taking less than 0.5 seconds for all four channels.

8.

How does the three-wire RTD setting affect my overall accuracy? When
using the three-wire setting in the Model 1529, a partial compensation of
lead-wire resistance is performed as per normal industry practices. Since
a three-wire measurement can’t fully compensate for lead resistaance,
accuracy is reduced. As stated in the specification section of this manual,
you need to add 0.05Ω to the measurement accuracy plus the maximum
possible difference between the resistances of the lead wires.

Logging
1.

How many data points can the Model 1529 store? You can store up to
100 demand log readings and 8,000 autolog readings.

2.

What happens when the log memory is full? Logging stops once the
memory is full. Readings are not deleted to make room for new readings.

3.

How can I tell when the log memory is full? Full memory is indicated in
the log stats function in the logging menu. You can also program a field
in the lower display to show the autolog memory status.

4.

Can I use the Model 1529 for other applications while I am autologging?
Yes, the Model 1529 can be used while logging. However, keep in mind
that the channels that are displayed are also logged. Changing the channels affects the data that is logged.

from Hart.

3.

Can the Model 1529 be set to simultaneous measurement mode and log
to the serial port? Yes. The Model 1529 makes the measurements simultaneously and transmits them to the serial port. However, most printers
can’t print as fast as the data is logged so it doesn’t appear to be
simultaneous.

Other
1.

Can I update the Model 1529 firmware without sending in my unit? Yes.
Firmware updates include a utility program that installs the upgrade via
the RS-232 port.
