3.5. PNEUMATIC CONNECTIONS
Note To prevent dust from getting into the analyzer, it was shipped with small
plugs inserted into each of the pneumatic fittings on the rear panel.
Remove and store the dust plugs for future use, such as storage, moving,
shipping.
CAUTION!
Do not operate this instrument until you’ve removed dust plugs from SAMPLE and EXHAUST
ports on the rear panel!
Table 3-8: Inlet / Outlet Connector Descriptions
REAR PANEL LABEL FUNCTION
SAMPLE Connects the sample gas to the analyzer. When operating the analyzer
without zero span option, this is also the inlet for any calibration gases.
EXHAUST Connects the exhaust of the analyzer with the external vacuum pump.
SPAN On Units with a zero/span valve, this port connects the external calibration gas
to the analyzer.
ZERO AIR On Units with a zero/span valve, this port connects the zero air gas or the zero
air cartridge to the analyzer.
3.5.1. ABOUT ZERO AIR AND CALIBRATION (SPAN) GASES
3.5.1.1. Zero Air
Zero air or zero calibration gas is defined as a gas that is similar in chemical
composition to the measured medium but without the gas to be measured by the
analyzer, in this case NO and NO2. If your analyzer is equipped with an external zero
air scrubber option, it is capable of creating zero air from ambient air.
If your application is not a measurement in ambient air, the zero calibration gas should
be matched to the matrix of the measured medium. Pure nitrogen could be used as a
zero gas for applications where NOX is measured in nitrogen. Special considerations
apply if measuring NOX in a matrix that does not contain oxygen, see Section 8.3.11 for
more information.
3.5.1.2. Calibration (Span) Gas
Calibration (or Span) gas is a gas specifically mixed to match the chemical composition
of the type of gas being measured at near full scale of the desired measurement range.
In this case, NOX, NO and NO2 measurements made with the T200H/M, it is
recommended that you use a span gas with an NO concentration equal to 80% of the
measurement range for your application.
EXAMPLE: If the application is to measure between 0 ppm and 500 ppm, an
appropriate span gas concentration would be 400 ppm NOx.
07270B DCN6512
Teledyne API - Model T200H/T200M Operation Manual Getting Started
43
Even though NO gas in nitrogen could be used as a span gas, the matrix of the balance
gas is different and may cause interference problems or yield incorrect calibrations. The
same applies to gases that contain high concentrations of other compounds (for example,
CO2 or H2O). The span gas should match all concentrations of all gases of the measured
medium as closely as possible.
Cylinders of calibrated NO gas traceable to NIST-standard reference materials
specifications (also referred to as EPA protocol calibration gases) are commercially
available.

1. Attach a 1/4" exhaust line between the external pump and the EXHAUST port of the
analyzer.
2. Attach an additional 1/4" exhaust port of the pump.
CAUTION
The exhaust from the analyzer must be vented outside the shelter or immediate
area surrounding the instrument and conform to all safety requirements using
a maximum of 10 meters of 1/4” PTFE tubing.
3. Attach a sample inlet line to the SAMPLE inlet port. Ideally, the pressure of the
sample gas should be equal to ambient atmospheric pressure.
Note Maximum pressure of any gas at the SAMPLE inlet should not exceed 1.5
in-Hg above ambient pressure and ideally should equal ambient
atmospheric pressure.
In applications where the sample gas is received from a pressurized
manifold, a vent must be provided to equalize the sample gas with
ambient atmospheric pressure before it enters the analyzer.
The vented gas must be routed outside the immediate area or shelter
surrounding the instrument.
4. Once the appropriate pneumatic connections have been made, check all pneumatic
fittings for leaks using procedures defined in Section 7.5.1.
Figure 3-15 and Figure 3-16 show the internal pneumatic flow of the standard
configuration of the T200H and T200M respectively.

Note Pneumatic Diagrams do not reflect the physical layout of the instrument.
The most significant differences between the T200H and T200M versions in regards to
pneumatic flow are:
A bypass line leading directly from the particulate filter to the exhaust manifold is
present on the T200H, but not in the T200M.
The diameter of the critical flow orifice controlling the gas flow into the sample
chamber is smaller and therefore the flow rate of sample gas through the instrument
is lower.

3.5.3.1. Ambient Zero/Ambient Span Valves (OPT 50A)
The Model T200H/M NOx analyzer can be equipped with a zero/span valve option for controlling the flow of
calibration gases generated from external sources. This option contains two solenoid valves located inside the
analyzer that allow the user to switch either zero, span or sample gas to the instrument’s sensor.
The user can control these valves from the front panel keyboard either manually or by activating the instrument’s
CAL or AutoCal features (Section 5.8). The valves may also be opened and closed remotely through the serial
ports (Section 4.11) or through the external, digital control inputs (Section 4.15).
This option also includes a two-stage, external zero air scrubber assembly that removes all NO and NO2 from
the zero air source (ambient air). The scrubber is filled with 50% Purafil Chemisorbant® (for conversion of NO to
NO2) and 50% activated charcoal (for removal of NO2). This assembly also includes a small particle filter to
prevent scrubber particles to enter the analyzer as well as two more rear panel fittings so each gas can enter the
analyzer separately.
Figure 3-19 and Figure 3-20 show the internal, pneumatic layouts with the zero/span valve option installed for a
Model T200H and T200M respectively.

By activating the instrument’s AutoCal feature (Section 5.8),
Remotely by using the external digital control inputs (Section 4.15.1.2) or Ethernet
option.
Remotely through the RS-232/485 serial I/O ports (Section 4.11).
All supply lines should be vented outside of the analyzer’s enclosure. In order to
prevent back-diffusion and pressure drop effects, these vent lines should be between 2
and 10 meters in length.

3.5.3.2. Zero Scrubber/Dual Pressurized Span Valve (OPT 50D)
The zero air scrubber of Option 50D is a cartridge, which is used to produce and supply
zero air to the analyzer’s ZERO inlet port. The cartridge mounts to the outside rear panel
and contains two chemicals: 50% volume of Purafil Chemisorbant to convert NO to
NO2, followed by 50% volume of charcoal to absorb NO2.
The dual pressurized span valves of Option 50D are a special set of valves that allows
two separate NOx mixtures to enter the analyzer from two independent sources.
Typically these two gas mixtures will come from two, separate, pressurized bottles of
certified calibration gas: one mixed to produce a NO, NO2 or NOx concentration equal
to the expected span calibration value for the application and the other mixed to produce
a concentration at or near the midpoint of the intended measurement range. Individual
gas inlets, labeled HIGH SPAN and LOW SPAN are provided at the back on the
analyzer.
The valves allow the user to switch between the two sources via the front panel
touchscreen control buttons or from a remote location by way of either the analyzer’s
digital control inputs or by sending commands over its serial I/O port(s).
Note The analyzer’s software only allows the SLOPE and OFFSET to be
calculated when sample is being routed through the HIGH SPAN inlet.
The LOW SPAN gas is for midpoint reference checks only.

CAUTION!
If the presence of ozone is detected at any time, call Teledyne API Technical Support as soon
as possible:
800-324-5190 or email: sda_techsupport@teledyne.com
If you are unfamiliar with the theory of operation of the T200H/M analyzer, we
recommend that you read Section 8 before proceeding. For information on navigating
the analyzer’s software menus, see the menu trees described in Appendix A.
3.6.1. STARTUP
After the electrical and pneumatic connections are made, an initial functional check is in
order. Turn on the instrument. The pump and exhaust fan should start immediately. The
display will briefly show a logo splash screen at the start of initialization.
The analyzer should automatically switch to Sample Mode after completing the boot-up
sequence and start monitoring NOX, NO, NO2 gases. Allow a one-hour warm-up period.
During the warm-up period, the front panel display may show messages in the
Parameters field, such as WARNING messages.
3.6.2. WARNING MESSAGES
During warm-up, internal temperatures and other parameters may be outside of specified
limits. The software will suppress most warning conditions for 30 minutes after power
up.

3.6.3. FUNCTIONAL CHECK
After the analyzer’s components have warmed up for at least 30 minutes, verify that the
software properly supports any hardware options that were installed.
Check to make sure that the analyzer is functioning within allowable operating
parameters. Appendices A and C include a list of test functions viewable from the
analyzer’s front panel as well as their expected values. These functions are also useful
tools for diagnosing performance problems with your analyzer (Section 7). The
enclosed Final Test and Validation Data Sheet (part number 04490) lists these values
before the instrument left the factory. To view the current values of these test functions

3.7. CALIBRATION
An initial calibration and functional check should be conducted upon first-time startup.
Note Once you have completed the followng set-up procedures, please fill out
the quality questionnaire that was shipped with your unit and return it to
Teledyne API.
This information is vital to our efforts in continuously improving our
service and our products. Thank you.
3.7.1. BASIC NOX CALIBRATION PROCEDURE
The initial calibration should be carried out using the same reporting range set up as
used during the analyzer’s factory calibration. This will allow you to compare your
calibration results to the factory calibration as listed on the Final Test and Validation
Data Sheet.
The following procedure assumes that the instrument does not have any of the available
valve options installed. Section 5 contains instructions for calibrating instruments with
these options.
If both available DAS parameters for a specific gas type are being reported via the
instrument’s analog outputs e.g. NXCNC1 and NXCNC2, separate calibrations should
be carried out for each parameter.
Use the LOW button when calibrating for NXCNC1
Use the HIGH button when calibrating for NXCNC2.
See Sections 4.13.3 and 4.13.4 for more information on analog output reporting ranges.

4. OPERATING INSTRUCTIONS
To assist in navigating the analyzer’s software, a series of menu trees can be found in
Appendix A of this manual.
Note The flow charts appearing in this section contain typical representations
of the analyzer’s display during the various operations being described.
These representations may differ slightly from the actual display of your
instrument.
The ENTR button may disappear if you select a setting that is invalid or
out of the allowable range for that parameter, such as trying to set the 24-
hour clock to 25:00:00. Once you adjust the setting to an allowable value,
the ENTR button will re-appear.
4.1. OVERVIEW OF OPERATING MODES
The T200H/M software has a variety of operating modes. Most commonly, the analyzer
will be operating in SAMPLE mode. In this mode, a continuous read-out of the NO,
NO2 and NOx concentrations are displayed on the front panel and are available to be
output as analog signals from the analyzer’s rear panel terminals. Also, calibrations can
be performed, and TEST functions and WARNING messages can be examined.
The second most important operating mode is SETUP mode. This mode is used for
performing certain configuration operations, such as for the DAS system, configuring
the reporting ranges, or the serial (RS-232/RS-485/Ethernet) communication channels.
The SET UP mode is also used for performing various diagnostic tests during
troubleshooting.

out-of-range reading or the analyzer’s inability to calculate it. All pressure
measurements are represented in terms of absolute pressure. Absolute,
atmospheric pressure is 29.92 in-Hg-A at sea level. It decreases about 1
in-Hg per 300 m gain in altitude. A variety of factors such as air
conditioning and passing storms can cause changes in the absolute
atmospheric pressure.

4.3. CALIBRATION MODE
4.3.1. CALIBRATION FUNCTIONS
Pressing the CAL key switches the T200H/M into calibration mode. In this mode, the
user can calibrate the instrument with the use of calibrated zero or span gases.
If the instrument includes the zero/span valve option, the display will also include
CALZ and CALS buttons. Pressing either of these buttons also puts the instrument into
multipoint calibration mode.
The CALZ button is used to initiate a calibration of the zero point.
The CALS button is used to calibrate the span point of the analyzer. It is
recommended that this span calibration is performed at 90% of full scale of the
analyzer’s currently selected reporting range.
Because of their critical importance and complexity, calibration operations are described
in detail in Section 5.
4.4. SETUP MODE
The SETUP mode contains a variety of choices that are used to configure the analyzer’s
hardware and software features, perform diagnostic procedures, gather information on
the instruments performance and configure or access data from the internal data
acquisition system (DAS). The areas access under the Setup mode are:

4.7. SETUP DAS - USING THE DATA ACQUISITION SYSTEM
(DAS)
The T200H/M analyzer contains a flexible and powerful, internal data acquisition
system (DAS) that enables the analyzer to store concentration and calibration data as
well as a host of diagnostic parameters. The data points can cover days, weeks or
months of valuable measurements, depending on how the DAS is configured. The data
are stored in non-volatile memory and are retained even when the instrument is powered
off. Data are stored in plain text format for easy retrieval and use in common data
analysis programs (such as spreadsheet-type programs).
Note Please be aware that all stored data will be erased if the analyzer’s disk-
on-module, CPU board or configuration is replaced/reset.
The DAS is designed to be flexible. Users have full control over the type, length and
reporting time of the data. The DAS permits users to access stored data through the
instrument’s front panel or its communication ports. Teledyne API also offers
APICOM, a program that provides a visual interface for configuration and data retrieval
of the DAS or using a remote computer. Additionally, the analyzer’s four analog output
channels can be programmed to carry data related to any of the available DAS
parameters.
The principal use of the DAS is logging data for trend analysis and predictive
diagnostics, which can assist in identifying possible problems before they affect the
functionality of the analyzer. The secondary use is for data analysis, documentation and
archival in electronic format.
DAS STATUS
The green SAMPLE LED on the instrument front panel, which indicates the analyzer
status, also indicates certain aspects of the DAS status:
Table 4-6: Front Panel LED Status Indicators for DAS
LED STATE DAS STATUS
Off
System is in calibration mode. Data logging can be enabled or disabled for this mode.
Calibration data are typically stored at the end of calibration periods, concentration data
are typically not sampled, diagnostic data should be collected.
Blinking
Instrument is in hold-off mode, a short period after the system exits calibrations. DAS
channels can be enabled or disabled for this period. Concentration data are typically
disabled whereas diagnostic should be collected.
On Sampling normally.
The DAS can be disabled only by disabling or deleting its individual data channels.

4.7.1. DAS STRUCTURE
The DAS is designed around the feature of a “record”, an automatically stored single
data point. (e.g. concentration, PMT signal level, etc.). Records are organized into data
channels which are defined by properties that characterize the:
Type of date recorded (e.g. concentration, PMT signal level, etc.);
Trigger event that causes the record to be made (e.g. every minute, upon exiting
calibration mode, etc.);
How many records to be stored, as well as;
How the information is to be stored (e.g. average over 1 hour, individual points,
minimum value over last 5 minutes, etc.).
The configuration of each DAS channel is stored in the analyzer’s memory as a script,
which can be edited from the front panel or downloaded, edited and uploaded to the
instrument in form of a string of plain-text lines through the communication ports.
4.7.1.1. DAS Channels
The key to the flexibility of the DAS is its ability to store a large number of
combinations of triggering events and data parameters in the form of data channels.
Users may create up to 20 data channels. For each channel one triggering event is
selected and one or all of the T200H/M’s 25 data parameters are allowed. The number
of parameters and channels is limited by available memory.
The properties that define the structure of an DAS data channel are:
Table 4-7: DAS Data Channel Properties

4.7.1.2. DAS Parameters
Data parameters are types of data that may be measured by the analyzers instrumentality
concentrations of measured gases, temperatures of heated zones,, pressures and flows of
the pneumatic subsystem as well as calibration data such as slope and offset for each
gas. For each Teledyne API analyzer model, the list of available data parameters is
different, fully defined and not customizable (see Appendix A for a list of T200H/M
parameters).
Most data parameters have associated measurement units, such as mV, ppm, cm³/min,
etc., although some parameters have no units. The only units that can be changed are
those of the concentration readings according to the SETUP-RANGE settings.
Note The DAS does not keep track of the unit of each concentration value and
DAS data files may contain concentrations in multiple units if the unit was
changed during data acquisition.
Each data parameter has user-configurable functions that define how the data are
recorded.
Table 4-8: DAS Data Parameter Functions
FUNCTION EFFECT
PARAMETER Instrument-specific parameter name.
SAMPLE MODE INST: Records instantaneous reading.
AVG: Records average reading during reporting interval.
MIN: Records minimum (instantaneous) reading during reporting interval.
MAX: Records maximum (instantaneous) reading during reporting interval.
SDEV: Records the standard deviation of the data points recorded during the reporting
interval.
PRECISION Decimal precision of parameter value(0-4).
STORE NUM.
SAMPLES
OFF: stores only the average (default).
ON: stores the average and the number of samples in each average for a parameter.
This property is only useful when the AVG sample mode is used. Note that the
number of samples is the same for all parameters in one channel and needs to be
specified only for one of the parameters.
4.7.1.3. DAS Triggering Events
Triggering events define when and how the DAS records a measurement of any given
data channel. Triggering events are firmware-specific and are listed in Appendix A-5.
The most common triggering events are:
ATIMER: Sampling occurs at regular intervals specified by an automatic timer.
Trending information is often stored via such intervals, as either individual datum or
averaged.
EXITZR, EXITSP, SLPCHG (exit zero, exit span, slope change): Sampling at the
end of an irregularly occurring event such as calibration or when the slope changes.
These events create individual data points. Zero and slope values can be used to
monitor response drift and to document when the instrument was calibrated.

WARNINGS: Some data may be useful when stored if one of several warning
messages appears. This is helpful for trouble-shooting by monitoring when a
particular warning occurred.
4.7.2. DEFAULT DAS CHANNELS
The T200H/M is configured with a basic DAS configuration, which is enabled by
default. New data channels are also enabled by default but each channel may be turned
off for later or occasional use. Note that DAS operation is suspended while its
configuration is edited through the front panel. To prevent such data loss, it is
recommended to use the APICOM graphical user interface for DAS changes.
A set of default data channels has been included in the analyzer’s software for logging
nitrogen oxides concentrations, calibration and predictive diagnostic data. They are:
CONC: Samples NOX, NO and NO2 concentration at one minute intervals and
stores an average every hour with a time and date stamp along with the number of
(1-minute) samples within each average(for statistical evaluation). Readings during
calibration and calibration hold off are not included in the data. By default, the last
800 hourly averages are stored.
CALDAT: Every time a zero or span calibration is performed CALDAT logs
concentration, slope and offset values for NOX and NO with a time and date stamp.
The NOX stability (to evaluate calibration stability) as well as the converter
efficiency (for reference) are also stored. This data channel will store data from the
last 200 calibrations and can be used to document analyzer calibration. The slope
and offset data can be used to detect trends in (instrument response.
CALCHECK: This channel logs concentrations and the stability each time a zero or
span check (not calibration) is finished. This allows the user to track the quality of
zero and span responses over time and assist in evaluating the quality of zero and
span gases and the analyzer’s noise specifications. The last 200 data points are
retained.
DIAG: Daily averages of temperature zones, flow and pressure data as well as
some other diagnostic parameters (HVPS, AZERO). These data are useful for
predictive diagnostics and maintenance of the T200H/M. The last 1100 daily
averages are stored to cover more than four years of analyzer performance.
HIRES: Records one minute, instantaneous data of all active parameters in the
T200H/M. Short-term trends as well as signal noise levels can be detected and
documented. Readings during calibration and the calibration hold off period are
included in the averages. The last 1500 data points are stored, which covers a little
more than one day of continuous data acquisition. This data channel is disabled by
default but may be turned on when needed such as for trouble-shooting problems
with the analyzer.
The default data channels can be used as they are, or they can be customized from the
front panel or through APICOM to fit a specific application. The Teledyne API website
contains this default and other sample DAS scripts for free download. We recommend
that the user backs up any DAS configuration and its data before altering it.
Note Teledyne-API recommends downloading and storing existing data and the
DAS configurations regularly for permanent documentation and future
data analysis. Sending a DAS configuration to the analyzer through its
COM ports will replace the existing configuration and will delete all stored
data.

4.7.2.4. Editing DAS Parameters
Data channels can be edited individually from the front panel without affecting other
data channels. However, when editing a data channel, such as during adding, deleting or
editing parameters, all data for that particular channel will be lost, because the DAS can
store only data of one format (number of parameter columns etc.) for any given channel.
In addition, an DAS configuration can only be uploaded remotely as an entire set of
channels. Hence, remote update of the DAS will always delete all current channels and
stored data.
To modify, add or delete a parameter, follow the instruction shown in section 4.7.2.2

4.7.2.5. Sample Period and Report Period
The DAS defines two principal time periods by which sample readings are taken and
permanently recorded:
SAMPLE PERIOD: Determines how often DAS temporarily records a sample
reading of the parameter in volatile memory. The SAMPLE PERIOD is set to one
minute by default and generally cannot be accessed from the standard DAS front
panel menu, but is available via the instruments communication ports by using
APICOM or the analyzer’s standard serial data protocol.
SAMPLE PERIOD is only used when the DAS parameter’s sample mode is set for
AVG, MIN or MAX.
REPORT PERIOD: Sets how often the sample readings stored in volatile memory
are processed, (e.g. average, minimum or maximum are calculated) and the results
stored permanently in the instrument’s Disk-on-Module as well as transmitted via
the analyzer’s communication ports. The REPORT PERIOD may be set from the
front panel.
If the INST sample mode is selected the instrument stores and reports an instantaneous
reading of the selected parameter at the end of the chosen REPORT PERIOD
In AVG, MIN or MAX sample modes, the settings for the SAMPLE PERIOD and the
REPORT PERIOD determine the number of data points used each time the average,
minimum or maximum is calculated, stored and reported to the com ports. The actual
sample readings are not stored past the end of the of the chosen REPORT PERIOD.
Also, the SAMPLE PERIOD and REPORT PERIOD intervals are synchronized to
the beginning and end of the appropriate interval of the instruments internal clock.
If SAMPLE PERIOD were set for one minute the first reading would occur at the
beginning of the next full minute according to the instrument’s internal clock.
If the REPORT PERIOD were set for of one hour the first report activity would occur
at the beginning of the next full hour according to the instrument’s internal clock.
EXAMPLE: Given the above settings, if DAS were activated at 7:57:35 the first sample
would occur at 7:58 and the first report would be calculated at 8:00 consisting of data
points for 7:58. 7:59 and 8:00.
During the next hour (from 8:01 to 9:00) the instrument will take a sample reading every
minute and include 60 sample readings.
When the STORE NUM. SAMPLES feature is turned on the instrument will also store
how many sample readings were used for the AVG, MIN or MAX calculation but not
the readings themselves.
4.7.2.6. Report Periods in Progress when Instrument Is Powered Off
If the instrument is powered off in the middle of a REPORT PERIOD, the samples
accumulated so far during that period are lost. Once the instrument is turned back on,
the DAS restarts taking samples and temporarily them in volatile memory as part of the
REPORT PERIOD currently active at the time of restart. At the end of this REPORT
PERIOD only the sample readings taken since the instrument was turned back on will
be included in any AVG, MIN or MAX calculation. Also, the STORE NUM.
SAMPLES feature will report the number of sample readings taken since the instrument
was restarted.

4.7.2.7. Number of Records
The DAS is capable of capturing several months worth of data, depending on the
configuration. Every additional data channel, parameter, number of samples setting etc.
will reduce the maximum amount of data points somewhat. In general, however, the
maximum data capacity is divided amongst all channels (max: 20) and parameters (max:
50 per channel).
The DAS will check the amount of available data space and prevent the user from
specifying too many records at any given point. If, for example, the DAS memory space
can accommodate 375 more data records, the ENTR key will disappear when trying to
specify more than that number of records. This check for memory space may also make
an upload of an DAS configuration with APICOM or a Terminal program fail, if the
combined number of records would be exceeded. In this case, it is suggested to either
try from the front panel what the maximum number of records can be or use trial-and-
error in designing the DAS script or calculate the number of records using the DAS or
APICOM manuals. To set the number of records for one channel from the front panel,
follow the instruction shown in section 4.7.2.2 then press.

4.7.2.9. Compact Report
When enabled, this option avoids unnecessary line breaks on all RS-232 reports. Instead
of reporting each parameter in one channel on a separate line, up to five parameters are
reported in one line, instead. For example, channel DIAG would report its record in two
lines (10 parameters) instead of 10 lines. Individual lines carry the same time stamp and
are labeled in sequence.
4.7.2.10. Starting Date
This option allows to specify a starting date for any given channel in case the user wants
to start data acquisition only after a certain time and date. If the Starting Date is in the
past, the DAS ignores this setting.

4.7.3. REMOTE DAS CONFIGURATION
Editing channels, parameters and triggering events as described in 6.7 is much more
conveniently done in one step through the APICOM remote control program using the
graphical interface shown in Figure 4-4. Refer to Section 4.15 for details on remote
access to the T200H/M analyzer.
Figure 4-4: APICOM Graphical User Interface for Configuring the DAS
Once a DAS configuration is edited (which can be done offline and without interrupting
DAS data collection), it is conveniently uploaded to the instrument and can be stored on
a computer for later review, alteration or documentation and archival. Refer to the
APICOM manual for details on these procedures. The APICOM user manual is
included in the APICOM installation file, which can be downloaded at
http://www.teledyne-api.com/software/apicom/.
Note Whereas the editing, adding and deleting of DAS channels and
parameters of one channel through the front-panel touch screen can be
done without affecting the other channels, uploading a DAS configuration
script to the analyzer through its communication ports will erase all data,
parameters and channels by replacing them with the new DAS
configuration. It is advised to download and backup all data and the
original DAS configuration before attempting any DAS changes.

4.8. SETUP RNGE: RANGE UNITS AND DILUTION
CONFIGURATION
This Menu is used to set the units of measure to be associated with the analyzer’s
reporting ranges (see Section 4.13.4.2. for more information on reporting ranges vs.
physical ranges) and for instruments with the sample gas dilution option operating, to set
the dilution ratio.
4.8.1. RANGE UNITS
The T200H/M can display concentrations in parts per million (106 mols per mol, PPM)
or milligrams per cubic meter (mg/m3, MGM). Changing units affects all of the
display, COM port and DAS values for all reporting ranges regardless of the analyzer’s
range mode. To change the concentration units:

Conversion factors from volumetric to mass units used in the T200H/M:
NO: ppm x 1.34 = mg/m3
NO2: ppm x 2.05 = mg/m3
Concentrations displayed in mg/m3 and µg/m3 use 0° C and 760 Torr as standard
temperature and pressure (STP). Consult your local regulations for the STP used by
your agency. EPA protocol applications, for example, use 25° C as the reference
temperature. Changing the units may cause a bias in the measurements if standard
temperature and pressure other than 0C and 760 Torr are used. This problem can be
avoided by recalibrating the analyzer after any change from a volumetric to a mass unit
