3. GETTING STARTED
3.1. Unpacking and Initial Setup
CAUTION
The M9110EH weighs about 17 kg (40 pounds) without options installed. To avoid
personal injury, we recommend to use two persons to lift and carry the analyzer.
Inspect the received packages for external shipping damage. If damaged, please advise the
shipper first, then TAI.
Included with your analyzer is a printed record (Form number 04490) of the final performance characterization performed on your instrument at the factory. This record is an
important quality assurance and calibration record for this instrument. It should be placed
in the quality records file for this instrument.
• Carefully remove the top cover of the analyzer and check for internal shipping
damage.
• Remove the set screw located in the top, center of the rear panel.
• Remove the screws fastening the top cover to the unit (four per side).
• Lift the cover straight up.
CAUTION
Printed Circuit Assemblies (PCA) are static sensitive. Electrostatic discharges, too
small to be felt by humans, are large enough to destroy sensitive circuits.
Before touching a PCA, fasten a properly installed grounding strap to your wrist or
touch a bare metal part of the chassis to discharge any electrostatic potentials.
Never disconnect electronic circuit boards, wiring harnesses or electronic
subassemblies while the unit is under power.
Do not position the equipment so that it is difficult to operate the disconnecting
device.
• Inspect the interior of the instrument to make sure all circuit boards and other
components are in good shape and properly seated.
• Check the connectors of the various internal wiring harnesses and pneumatic hoses
to make sure they are firmly and properly seated.
• Verify that all of the optional hardware ordered with the unit has been installed.
These are checked on the paperwork (Form 04490) accompanying the analyzer.
• Once you have determined that no shipping damage exists and the unit includes all
expected hardware options, remove three, red colored shipping screws from the
bottom of the chassis, shown in Figure 3-1.

3.3. Pneumatic Connections
Sample and calibration gases should only come into contact with PTFE (Teflon), FEP, glass
or stainless steel materials. Figure 3-5 and Figure 3-6 illustrate the most common
configurations for gas supply and exhaust lines to the Model 9110EH Analyzer. Appendix D
contains more detailed pneumatic flow diagrams for the analyzer and its various
(pneumatically related) options.
CAUTION
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. Make sure that all
dust plugs are removed before attaching exhaust and supply gas lines.
Please refer to Figure 3-3 for pneumatic connections at the rear panel and Table 3-1 for
nomenclature.
Table 3-1: Inlet / Outlet Connector Nomenclature
Rear Panel Label Function
Sample
Exhaust Connects the exhaust of the analyzer with the external vacuum pump.
Span
Zero Air
Connects the sample gas to the analyzer. When operating the analyzer
without zero span option, this is also the inlet for any calibration gases.
On Units with zero/span valve or IZS option installed, this port
connects the external calibration gas to the analyzer.
On Units with zero/span valve or IZS option installed, this port
connects the zero air gas or the zero air cartridge to the analyzer.
• Attach a sample inlet line to the sample inlet port. Ideally, the pressure of the
sample gas should be equal to 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 needs to be routed outside the immediate area or shelter surrounding the instrument.
CAUTION
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.
CAUTION
The exhaust from the external pump needs to be vented outside the
immediate area or shelter surrounding the instrument using a
maximum of 10 meters of 1/4” PTFE tubing.

• Attach the 1/4" exhaust line to the exhaust port of the analyzer and to the inlet port
of the pump.
• Attach zero air and span gas supply lines as appropriate (Figure 3-5 and Figure 3-6)
to the rear panel (Figure 3-3). For this type of analyzer, zero air and span gas are
defined as follows.

Span gas is defined as 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. To

Model 9110EH Instruction Manual Getting Started
For example, if the measurement is NOX in ambient air between 0 and 500 ppb, an
appropriate span gas would be NO in air at 400 ppb NO concentration (80% of maximum
range). 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, CO
or H2O). The span gas should match all concentrations of all gases of the
2
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.
Some applications, such as EPA monitoring, require a multipoint calibration where span
gases of different concentrations are needed. We recommend using an NO gas of higher
concentration combined with a gas dilution calibrator such as a T-API Model 700. This type
of calibrator mixes a high concentration gas with zero air (both supplied externally) to
accurately produce span gas of the desired concentration. Linearity profiles can be
automated with this model and run unattended overnight. The dynamic range of the M700
is about 0.1 to 0.001 times the original span concentration.
If a dynamic dilution system such as the TAI model 700 is used to dilute high concentration gas standards to low, ambient concentrations, ensure that the NO concentration of the
reference gas matches the dilution range of the calibrator. Choose the NO gas concentration
such that the dynamic dilution system operates in its mid-range and not at the extremes of
its dilution capabilities. For example, a dilution calibrator with 10-10000 dilution ratio will
not be able to accurately dilute a 5000 ppm NO gas to a final concentration of 500 ppb, as
this would operate at the very extreme dilution setting. A 100 ppm NO gas in nitrogen is
much more suitable to calibrate the M9110EH analyzer (dilution ratio of 222, in the mid-range
of the system’s capabilities).
3.3.2. Zero Gas Defined
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 NO
capable of creating zero air from ambient air. However, 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
NO
For analyzers without zero air options, a zero air generator such as the TAI Model 701 can
be used. Please visit the company website for more information.
If your analyzer is equiped with either the zero/span valve option (Option 50) or the
internal zero/span option (Option 51), the pneumatic connections should be made as shown
in Figure 3-6 (see also Appendix D for detailed diagram).

3.4.3. Ethernet Connection and Configuration
If your M9110EH is equipped with an Ethernet option (described in Section 5.8.3), the
analyzer needs to be configured to match the network settings of your internal network.
Please change the first three of the following parameters to configure the Ethernet
functionality:
• (IP) A static IP address (default value is 000.000.000.000).
• (GTWY) A static network gateway IP address (default is 000.000.000.000).
• (SNET) A subnet mask (default is 255.255.255.0).
• (PORT) A TCP/IP port number (default is 3000, does not need to be changed).
Note that the M9110EH currently does not support DHCP or dynamic IP addresses. All of the
above settings can be changed by following the procedure described in Section 6.9.9 of this
manual. To do this quickly, press the following keys on the analyzer’s front panel: SETUP
– MORE – COMM – INET and configure the individual items shown on the menu and listed
above.
3.5. Initial Operation
If you are unfamiliar with the theory of operation of the M9110EH analyzer, we recommend
that you read Chapter 10 before proceeding. For information on navigating the analyzer’s
software menus, see the menu trees described in Appendix A.1.
3.5.1. Startup
After electrical and pneumatic connections are made, turn on the instrument and supply
power to the external pump. The exhaust and PMT cooler fans should start. The display
should immediately display a single, horizontal dash in the upper left corner of the display.
This will last approximately 30 seconds while the CPU loads the operating system. Once the
CPU has completed this activity, it will begin loading the analyzer firmware and configuration data. During this process, a string of messages will appear on the analyzer’s front panel
display as shown in Figure 3-10. The analyzer should automatically switch to SAMPLE
mode after completing the boot-up sequence and start monitoring NO
, NO, NO2 gases.

3.6. First Calibration
3.6.1. Basic Calibration Procedure
The initial calibration should be carried out using the 500 ppb range, a span gas with about
400 ppb NO and with the unit set for SINGLE range, which will enable you to compare your
calibration results to the factory calibration as listed on the Final Test and Validation Data
Sheet. The following three-step procedure assumes that the instrument does not have any
of the available zero/span (Z/S) valve options installed. Chapter 7 contains instructions for
calibrating instruments with Z/S valve options, Chapter 8 for EPA protocol calibration.

GLOSSARY
4.1. Frequently Asked Questions
The following list contains some of the most commonly asked questions relating to the
Model 9110EH NO
Q: Why is the ZERO or SPAN key not displayed during calibration?
A: The M9110EH disables certain keys whenever the chosen value is out of range for that
particular parameter. In this case, the expected span or zero value is too different from the
actually measured value and the instrument does not allow to span or zero to that point. If,
for example, the span set point is 400 ppb and the measurement response is only 50 ppb,
the SPAN button will not appear to prevent the user from spanning to an out-of-range
response curve. Chapter 11 describes this in detail.
Q: Why does the ENTR key sometimes disappear on the front panel display?
A: Sometimes the ENTR key will 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
or a range to less than 10 or more than 20000 ppb. Once you adjust the setting to an
allowable value, the ENTR key will re-appear.

Q: Why does the analyzer not respond to span gas?
A: There are several reasons why this can happen. Section 11.3.2 has some possible
answers to this question.
Q: Can I automate the calibration of my analyzer?
A: Any analyzer with zero/span valve or IZS option can be automatically calibrated using
the instrument’s AutoCal feature.
Q: Can I use the IZS option to calibrate the analyzer?
A: Yes. However, the accuracy of the IZS option’s permeation tube is only ±5%. Whereas
this may be acceptable for basic calibration checks, the IZS option is not permitted as a
calibration source in applications following US EPA protocols. To achieve highest accuracy, it
is recommended to use cylinders of calibrated span gases in combination with a zero air
source. TAI offers a zero air generator Model 701 and a gas dilution calibrator Model 700
for this purpose.
Q: What do I do if the concentration on the instrument's front panel display does not match
the value recorded or displayed on my data logger even if both instruments are properly
calibrated?
A: This most commonly occurs for one of the following reasons: (1) a difference in circuit
ground between the analyzer and the data logger or a wiring problem; (2) a scale problem
with the input to the data logger. The analog outputs of the analyzer can be manually
calibrated to compensate for either or both of these effects, see Section 6.7; analog outputs
are not calibrated, which can happen after a firmware upgrade (Section 6.7.3.2).
Q: How do I measure the sample flow?
A: Sample flow is measured by attaching a calibrated flow meter to the sample inlet port
when the instrument is operating. The sample flow should be 500 cm³/min ±10%.
Chapter 11 includes detailed instructions on performing a check of the sample gas flow.

Frequently Asked Questions & Glossary Model 9110EH Instruction Manual
Q: How often do I need to change the particulate filter?
A: Once per week. Table 9-1 contains a maintenance schedule listing the most important,
regular maintenance tasks. Highly polluted sample air may require more frequent changes.
Q: How long does the sample pump last?
A: The sample pump should last one to two years and the pump head should be replaced
when necessary. Use the RCEL pressure indicator on the front panel to see if the pump
needs replacement. If this value goes above 10 in-Hg-A, on average, the pump head needs
to be rebuild.
Q: Do I need a strip chart recorder or external data logger?
A: No, the M200E is equipped with a very powerful internal data acquisition system (iDAS).
Section 6.9.10 describes the setup and operation in detail.
Q: Why does my RS-232 serial connection not work?
A: There are many possible reasons: 1) the wrong cable, please use the provided or a
generic “straight-through” cable (do not use a “null-modem” type cable), 2) The DCE/DTE
switch on the back of the analyzer is not set properly; make sure that both green and red
lights are on, 3) the baud rate of the analyzer’s COM port does not match that of the serial
port of your computer/data logger. See Section 11.5.11 more trouble-shooting information.

5.1. External Pumps
The M9110EH comes equipped with an external pump specified upon ordering. Whereas the
analyzer can be re-configured for other voltages, operation at other than the original
voltage/frequency may require a different external pump. A variety of external pumps are
available for the M9110EH series analyzers. The range of available pump options meets all
typical AC power supply standards while exhibiting the same pneumatic performance.
Description
External pump for 115 VAC / 60 Hz power supply
External pump for 230 VAC / 50 Hz power supply
External pump for 110 VAC / 50 Hz power supply
External pump for 100 VAC / 50 Hz power supply
External pump for 220-240 VAC / 50-60 Hz power supply
5.2. Rack Mount Kits
There are several options for mounting the analyzer in standard 19” racks. The slides are
three-part extensions, one mounts to the rack, one mounts to the analyzer chassis and the
middle part remains on the rack slide when the analyzer is taken out. The analyzer locks
into place when fully extended and cannot be pulled out without pushing two buttons, one
on each side.
The rack mount brackets for the analyzer requires that you have a support structure in your
rack to support the weight of the analyzer. The brackets cannot carry the full weight of an
analyzer and are meant only to fix the analyzer to the front of a rack and to prevent it from
sliding out of the rack through user intervention or vibration.
Option Number Description
OPT 20A Rack mount brackets with 26 in. chassis slides.
OPT 20B Rack mount brackets with 24 in. chassis slides.
OPT 21 Rack mount brackets only
OPT 23 Rack mount for external pump (no slides).
5.3. Carrying Strap Handle
The chassis of the M9110EH analyzer allows to attach a strap handle for carrying the
instrument (Figure 5-1). The handle is located on the right side and pulls out to
M9110EH Rev 0 35
Optional Hardware and Software Model 9110EH Instruction Manual
accommodate a hand for transport. When pushed in, the handle is flush with the chassis
and protrudes out about 9 mm / 3/8”. Installing the strap handle prevents the use of the
rack mount slides, although the rack mount brackets, Option 21, can still be used. We
caution any user to prevent personal injury when using the strap handle, as the analyzer
without options installed weighs about 17 kg (38 pounds). Make sure to disconnect all
cables and tubing from the analyzer before carrying it.
Figure 5-1: M9110EH with Carrying Strap Handle and Rack Mount Brackets
5.4. Current Loop Analog Outputs
This option adds isolated, voltage-to-current conversion circuitry to the analyzer’s analog
outputs. This option may be ordered separately for the first three of the analog outputs and
can be installed at the factory or added later. Call TAI sales for pricing and availability.
The current loop option can be configured for any output range between 0 and 20 mA (for
example 0-20, 2-20 or 4-20 mA). Information on calibrating or adjusting these outputs can
be found in Section 6.7.6.

5.6. Calibration Valve Options
5.6.1. Zero/Span Valves
The Model 9110EH NO
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 7.8). The valves may also be opened and closed remotely through the serial ports
(Section 6.9) or through the external, digital control inputs (Section 6.8).
This option also includes a two-stage, external zero air scrubber assembly that removes all

The state of the IZS valves can also be controlled:
• Manually from the analyzer’s front panel by using the SIGNAL I/O controls located
under the DIAG Menu (Section 6.8.1),
• By activating the instrument’s AutoCal feature (Section 7.8),
• Remotely by using the external digital control inputs (Section 6.9), or
• Remotely through the RS-232/485 serial I/O ports (Section 6.9.10).

Sources of zero and span gas flow must be capable of supplying at least 600 cm
/min as
the analyzer draws about 500±50 cm³/min into the instrument. Both 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.
5.6.2. Internal Zero/Span (IZS)
The M9110EH can be equipped with an internal zero air and span gas generator system (IZS).
This option includes a heated enclosure for a NO
producing zero air and two valves for switching between the sample gas inlet and the
output of the zero/span subsystem, functionally identical to the zero/span valve option.
The IZS option includes a two stage, external zero air scrubber assembly that removes all
NO & NO
from the zero air source. The scrubber is filled with 50% Purafil Chemisorbant
2
(for conversion of NO to NO2) and 50% activated charcoal (for removal of NO2). This
assembly also includes a small particle filter.
Span gas is created by passing zero air over a NO
liquid NO
air. The concentration of the NO
, which slowly permeates through a permeable membrane into the surrounding
2
span gas is determined by three factors:
2
• Size of the membrane: The larger the area of the membrane, the more permeation
occurs.
• Temperature of the NO
: Increasing the temperature of the permeation tube
2
increases the pressure inside the tube and therefore increases the rate of
permeation.
• Flow rate of the zero air: If the previous two variables are constant, the permeation
rate of the NO
into the zero air stream will be constant. Therefore, a lower flow rate
2
of zero air produces higher concentrations of NO
permeation tube, an external scrubber for
2
permeation tube. This tube contains

.
2
®
38 M9110EH Rev 0
Model 9110EH Instruction Manual Optional Hardware and Software
In order to keep the permeation rate constant, the IZS enclosure is heated by a PID
(Proportional/Integral/Derivative) temperature control loop to a constant 50° C (10° above
the maximum operating temperature of the instrument). A thermistor measures the actual
temperature and reports it to the CPU for control feedback. The flow rate across the IZS
oven is controlled with a critical flow orifice to 60±5 cm³/min.
Please note, that the IZS option does not contain the actual permeation tube, which needs
to be ordered separately. See next option for description.
CAUTION
Gas flow must be maintained at all times for units with a permeation tube
installed. Insufficient gas flow allows NO2 gas to build up to levels that will
severely contaminate the instrument.
Figure 3-12 shows the internal pneumatic connections for a Model 9110EH with IZS option
installed. Table 5-1 shows the operational state of the valves associated with the IZS option
during the analyzer’s various operational modes. SPAN gas on the zero/span valve option is
equivalent with the permeation tube NO
gas stream on the IZS option.
2
The state of the IZS valves can also be controlled:
• Manually from the analyzer’s front panel by using the SIGNAL I/O controls located
under the DIAG Menu (Section 6.8.1),
• By activating the instrument’s CAL or AutoCal features (Section 7.8),
• Remotely by using the external digital control inputs (Section 6.9), or
• Remotely through the RS-232/485 serial I/O ports (Section 6.9.10).

5.7. Scrubbers and Expendables
5.7.1. Charcoal Scrubber
This kit includes a charcoal scrubber cartridge, which is used to remove NO2 from an
exhaust port. Applications include, but are not limited to, the removal of NO
pump exhaust if that exhaust cannot be vented outside the analyzer shelter or if the vent
line is not far enough away from the analyzer inlet port (in which case the exhaust would be
measured again by the analyzer). The kit does not include any mounting clips, filters or
tubing. To order a refill for this cartridge, specify the refill kit listed below.
Older models of the nitrogen oxides analyzer used this type of charcoal scrubber to remove
both NO
and excess ozone from the exhaust. However, we do not recommend this

The zero air scrubber exit contains a particle filter that retains any dust coming from the
cartridge and connects with a 0.25” PVC tubing to the ZERO inlet port. The chemicals need
to be exchanged periodically (use Option 43) to prevent saturation and break-through of
into the zero air stream. This kit is recommended if no other zero air source is available

5.8. Communication Options
5.8.1. RS232 Modem Cables
The analyzer is shipped with a standard, shielded, straight-through DB-9F to DB-9F cable of
about 1.8 m length, which should fit most computers of recent build. An additional cable of
this type can be ordered.
Option 60A consists of a shielded, straight-through serial cable of about 1.8 m length to
connect the analyzer’s COM1 port to a computer, a code activated switch or any other
communications device that is equipped with a DB-25 female connector. The cable is
terminated with one DB-9 female connector and one DB-25 male connector. The DB-9
connector fits the analyzer’s COM1 port.
5.8.2. RS-232 Multidrop
The multidrop option is used with any of the RS-232 serial ports to enable communications
of several analyzers with the host computer over a chain of RS-232 cables. The option
consists of a small box, which can be attached to the analyzer, with a termination switch, a
power connector and two serial ports, one incoming from the analyzer (cable supplied) and
one outgoing port to the next analyzer’s multi-drop box (requires additional cable
Option). One is required per analyzer. The first incoming port on the first box
connects to the host computer and the outgoing port on the last multi-drop box needs to be
terminated. Setup and user instructions are covered in the TAI Multidrop Manual.
5.8.3. Ethernet
The Ethernet option allows the analyzer to be connected to any 10BaseT local area network.
When installed, this option is electronically connected to the instrument’s COM2 serial port
making that port no longer available for RS-232/RS-485 communications through the COM2
connector on the rear panel. The option consists of a TAI designed Ethernet card
(Figure 5-3), which is mechanically attached to the instrument’s rear panel. A 2 m long,
CAT-5 network cable terminated at both ends with standard RJ-45 connectors is included as
well. Maximum communication speed is limited by the RS-232

6.2.3. Calibration Functions
Pressing the CAL key switches the M9110EH 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 either the zero/span valve option or IZS option, the display will
also include CALZ and CALS keys. Pressing either of these keys also puts the instrument
into multipoint calibration mode.
The CALZ key is used to initiate a calibration of the zero point.
The CALS key is used to calibrate the span point of the analyzer. It is recommended that
this span calibration is about 80-90% of full scale of the analyzer’s operating range.
48 M9110EH Rev 0
Model 9110EH Instruction Manual Operating Instructions
Chapter 7 details all calibration operations, Chapter 1 describes the zero/span valve and
IZS options.
6.3. Calibration Mode
Owing to its importance, calibration is described separately in Chapter 7, EPA protocol
calibration in Chapter 8.
6.4. Setup Mode
The SETUP mode contains a variety of choices that are used to configure the analyzer’s
hardware and software features and to read or configure the internal data acquisition
system (iDAS). For a visual representation of the software menu trees, refer to
Appendix A-1.
NOTE
Any changes made to a variable during one of the following procedures is not
acknowledged by the instrument until the ENTR Key is pressed
If the EXIT key is pressed before the ENTR key, the analyzer will beep, alerting the user
that the newly entered value has not been accepted.
Some of the functions of the SETUP mode are described in separate sections following this
section. In particular, the RNGE function can be found in Section 6.5, the ACAL function in
Section 7.8.
6.4.1. Password (PASS)
The M9110EH provides password protection of the calibration and setup functions to prevent
unauthorized adjustments. When the passwords have been enabled in the PASS menu
item, the system will prompt the user for a password anytime a password-protected
function is requested.
There are three levels of password protection, which correspond to operator, maintenance,
and configuration functions. Each level allows access to all of the functions in the previous
level.

6.5. Setup - Range Configuration (RNGE)
The analyzer has four analog output signals, accessible through a connector on the rear
panel.

Figure 0-1: Analog Output Connector Key
All of these outputs can be configured either at the factory or by the user for full scale
outputs of 0.1 V, 1V, 5V or 10V. Additionally A1, A2 andA3 may be equipped with optional
0-20 mA current loop drivers and configured for any current output within that range
(e.g. 0-20, 2-20, 4-20, etc.).
Channels A1, A2 and A3 report analog signals that are proportional to the NO
concentrations of the sample gas, respectively. Analog output voltage or current can be

analyzer has two physical ranges for determining NO
x
the output signals from the preamplifier board. Internally, the analyzer’s signal resolution is
about 16-bit or 72000 counts per 5 V PMT signal. The low range spans 0 to 2000 ppb NO
(2000 ppb = 5 V) whereas the high range spans 0-20000 ppb NO
(20000 ppb = 5 V). Both
X
ranges need to be calibrated independently to the same span gases in order to allow
switching back and forth between high and low ranges. Once properly calibrated, the
analyzer’s front panel will accurately report concentrations between 0 and 20000 ppb,
regardless of the selected analog range. To switch between physical ranges, the user has to
specify an appropriate analog output range from the front panel. Any analog range between
0 and 2000 ppb will cause the analyzer to remain in the low physical range. Any upper
analog range limit between 2001 and 20000 ppb will cause the instrument to operate in its
high physical range.
For applications using chart recorders or other analog recording devices, such a wide range
can usually not be resolved on the output. For example, in an application where the
expected concentrations of NO, NO
2 and NOx
are typically less than 500 ppb, the full scale
of expected values is only 0.25% of the instrument’s 20000 ppb physical range. The
corresponding output signal would then only be recorded across 0.25% of the range of the
recording device.
x
X
, NO
The M200E solves this problem by allowing the user to select a reporting range for the
analog outputs that only includes that portion of the physical range that covers the specific
application. Note that only the reporting range of the analog outputs is scaled, the physical
ranges of the analyzer remain unaltered with the exception of the 2000/2001 ppb split. This
increases the reliability and accuracy of the analyzer by avoiding additional gain-amplification circuitry. If properly calibrated, both the iDAS values and the concentration values on
the front panel are also unaffected by any change in analog output ranges.
6.5.2. Reporting Range Modes
The M9110EH provides three analog output range modes to choose from.
• Single range mode (SNGL) sets all measured gases to the same output reporting
range.
• Independent range mode (IND) allows the reporting ranges for all gases to be
different.
• Automatic range mode (AUTO) gives the analyzer the ability to report data through
a low range and high range by automatically switching into the appropriate range as
the concentrations change.
Only one of the above range modes can be active at any time. To select output range types,
use the following key sequences.
M9110EH Rev 0 53
Operating Instructions Model 9110EH Instruction Manual
6.5.3. Single Range mode (SNGL)
The default range mode for the analyzer is single range, in which all analog concentration
outputs (usually A1, A2 and A3) are set to the same reporting range. This reporting range
can be set to any value between 100 ppb and 20000 ppb. However, the electronic signal
ranges of the analog outputs may still be configured for different values (e.g., 0-10 V and
0-0.1 V).

Conversion factors from volumetric to mass units used in the M9100EH:

3
; ppm x 1.34 = mg/m
3
NO2: ppb x 2.05 = µg/m3; ppm x 2.05 = mg/m3
3
Concentrations displayed in mg/m
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 0°C and 760 Torr are used. This problem can be avoided by recalibrating the analyzer after any change from a volumetric to a mass unit or vice versa.
CAUTION
In order to avoid a reference temperature bias, the analyzer must be recalibrated
after every change in reporting units.
6.5.7. Dilution Ratio
The dilution ratio is a software option that allows the user to compensate for any dilution of
the sample gas before it enters the sample inlet. Using the dilution ratio option is a 4-step
process:
• Select concentration units: Follow the procedure in Section 6.5.6.
M9110EH Rev 0 57
Operating Instructions Model 9110EH Instruction Manual
• Select the range: Use the procedures in Section 6.6. Make sure that the SPAN value
entered is the maximum expected concentration of the undiluted calibration gas and
that the span gas is either supplied through the same dilution inlet system as the
sample gas or has an appropriately lower actual concentration. For example, with a
dilution set to 100, a 1 ppm gas can be used to calibrate a 100 ppm sample gas if
the span gas is not routed through the dilution system. On the other hand, if a
100 ppm span gas is used, it needs to pass through the same dilution steps as the
sample gas.
• Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluent and 1
part of sample gas):

6.6. Setup - Internal Variables (VARS)
The M9110EH has several-user adjustable software variables, which define certain operational
parameters. Usually, these variables are automatically set by the instrument’s firmware,
but can be manually re-defined using the VARS menu. Table 0-5 lists all variables that are
available within the 818 password protected level. See Appendix A2 for a detailed listing of
all of the M9110EH variables that are accessible through the remote interface.
Table 0-5: Variable Names (VARS) Revision C.4
Variable Description Allowed Values
DAS_HOLD_OFF Duration of no data storage in the iDAS. This is the time
when the analyzer returns from one of its calibration
modes to the SAMPLE mode. The DAS_HOLD_OFF can be
disabled in each iDAS channel.
TPC_ENABLE Enables or disables the temperature and pressure
compensation (TPC) feature (Section 10.4.3).
DYN_ZERO Dynamic zero automatically adjusts offset and slope of
the NO and NOX response when performing a zero point
calibration during an AutoCal (Chapter 7).
DYN_SPAN Dynamic span automatically adjusts the offsets and
slopes of the NO and NOx response when performing a
zero point calibration during an AutoCal (Chapter 7).
Note that the DYN_ZERO and DYN_SPAN features are not
allowed for applications requiring EPA equivalency.
SFLOW_SET Adjusts the displayed value of the sample flow rate to the
actual flow rate, which was measured by the user.
Changing this value does not alter the actual sample gas
flow rate!
OFLOW_SET Adjusts the displayed value of the ozone flow rate to its
actual flow rate, which was measured by the user.
Changing this value does not alter the actual ozone gas
flow rate!
IZS_SET Sets the IZS oven temperature. Increasing or decreasing
this temperature will increase or decrease the NO2
permeation rate of the IZS source (Section 5.6.3).
CONC_PRECISION Allows to set the number of decimal points of the
concentration and stability parameters displayed on the
front panel.
CLOCK_ADJ Adjusts the speed of the analyzer’s clock. Choose the +
sign if the clock is too slow, choose the - sign if the clock
is too fast.
CAL_ON_NO2 Allows to turn ON and OFF the ability to span the
analyzer with NO2, in which case the instrument acts as if
NO and NOX are spanned, even though it is supplied with
NO2. The NO2 concentration is then zero by default.
This feature is not permitted for EPA protocol

6.7. Setup - Diagnostics (DIAG)
A series of diagnostic tools is grouped together under the SETUP-MORE-DIAG menu. As
these parameters are dependent on firmware revision, the menu trees are listed in detail in
Appendix A. The individual parameters, however, are explained in more detail in the
following section, indicated in Table 0-6. These tools can be used in a variety of troubleshooting and diagnostic procedures and are referred to in many places of the maintenance
and trouble-shooting sections.

6.7.3.2. Analog Output Calibration Mode
The analog outputs can be calibrated automatically or manually. In its default mode, the
instrument is configured for automatic calibration of all channels. Manual calibration should
be used for the 0.1V range or in cases where the outputs must be closely matched to the
characteristics of the recording device. Outputs configured for automatic calibration can be
calibrated as a group or individually. Analog calibration needs to be carried out on first
startup of the analyzer (performed in the factory as part of the configuration process) or
whenever re-calibration is required.
To calibrate the outputs as a group press SETUP-MORE-DIAG-ENTR-NEXT-NEXT and

6.7.3.3. Manual Analog Output Calibration
For highest accuracy, the voltages of the analog outputs can be manually calibrated. Note
that outputs configured for 0.1V full scale should always be calibrated manually. Calibration
is done through the instrument software with a voltmeter connected across the output
terminals (Figure 0-3). Adjustments are made using the front panel keys by setting the
zero-point first and then the span-point (Table 0-11). The software allows this adjustment
to be made in 100, 10 or 1 count increments.

Full Scale Zero Tolerance Span Voltage Span Tolerance
0.1 VDC ±0.0005V 90 mV ±0.001V
1 VDC ±0.001V 900 mV ±0.001V
5 VDC ±0.002V 4500 mV ±0.003V

6.7.3.4. Analog Output Offset Adjustment
Some analog signal recorders require that the zero signal is significantly different from the
baseline of the recorder in order to record slightly negative readings from noise around the
zero point. This can be achieved in the M200E by defining a zero offset, a small voltage
(e.g., 10% of span), which can be added to the signal of individual output channels just like
a strip chart recorder can be set to have a 10% offset by moving the pens. Set the offset by
pressing SETUP-MORE-DIAG-ENTR-NEXT-NEXT and the following keys:

6.7.3.5. Current Loop Output Adjustment
A current loop option is available and can be installed as a retrofit for each of the analog
outputs of the analyzer (Section 5.3). This option converts the DC voltage analog output to
a current signal with 0-20 mA output current. The outputs can be scaled to any set of limits
within that 0-20 mA range. However, most current loop applications call for either 2-20 mA
or 4-20 mA range. All current loop outputs have a +5% over-range. Ranges with the lower
limit set to more than 1 mA (e.g., 2-20 or 4-20 mA) also have a -5% under-range.
To switch an analog output from voltage to current loop, follow the instructions in
Section 6.7.1 and select CURR from the list of options on the “Output Range” menu.
Adjusting the signal zero and span values of the current loop output is done by raising or
lowering the voltage of the respective analog output. This proportionally raises or lowers
the current produced by the current loop option.
Similar to the voltage calibration, the software allows this current adjustment to be made in
100, 10 or 1 count increments. Since the exact current increment per voltage count varies
from output to output and from instrument to instrument, you will need to measure the
change in the current with a current meter placed in series with the output circuit
(Figure 0-4).

6.7.5. Optic Test
The optic test function tests the response of the PMT sensor by turning on an LED located in
the cooling block of the PMT (Fig. 10-15). The analyzer uses the light emitted from the LED
to test its photo-electronic subsystem, including the PMT and the current to voltage

6.7.6. Electrical Test
The electrical test function creates a current, which substitutes the PMT signal, and feeds it
into the preamplifier board. This signal is generated by circuitry on the pre-amplifier board
itself and tests the filtering and amplification functions of that assembly along with the A/D
converter on the motherboard. It does not test the PMT itself. The electrical test should
produce a PMT signal of about 2000 ±1000 mV.

6.7.8. Flow Calibration
The flow calibration allows the user to adjust the values of the sample and ozone flow rates
as they are displayed on the front panel and reported through COM ports to match the
actual flow rate measured at the respective pneumatic ports. This does not change the
hardware measurement of the flow sensors, only the software calculated values. This is one
of the two parameters in the DIAG menu that is retained after you exit the menu. To carry
out this adjustment, connect an external, sufficiently accurate flow meter to the respective
test port (Chapter 11 contains more details on this setup). Once the flow meter is attached
and measures the actual flow, follow this key sequence:

6.8. Digital Inputs and Outputs
6.8.1. Status Outputs
The status output signals report analyzer conditions through optically isolated transistors
which can sink up to 50 mA of DC current to ground. These outputs can be used with
interface devices that accept logic-level digital inputs, such as programmable logic
controllers (PLC).
NOTE
Most PLC devices have internal provisions for limiting the current that the output
can draw from an external device. When connecting the M200E status outputs to a
unit that does not have this feature, a 120 Ω external pull-up resistors must be
used to limit the current through the transistor output to 50 mA or less. Refer to
the motherboard schematic 04069 in Appendix D.
76 M9110EH Rev 0
Model 9110EH Instruction Manual Operating Instructions
The status outputs are accessed through a 12 pin connector on the analyzer’s rear panel

6.9. Setup - Communication Ports (COMM)
The M9110EH is equipped with two serial communication ports located on the rear panel
(Figure 3-3). Both ports operate similarly and give the user the ability to communicate with,
issue commands to, and receive data from the analyzer through an external computer
system or terminal. By default, both ports operate on the RS-232 protocol. The COM2 port,
78 M9110EH Rev 0
Model 9110EH Instruction Manual Operating Instructions
however, can be configured for half-duplex RS-485 communication or can be used for the
T-API Ethernet interface card (optional equipment, Section 5.7.3).
There are two options to connect multiple analyzers to a single computer terminal or data
logging device over a single serial communications line. Either port can be equipped with an
optional RS-232 multidrop assembly (Section 5.7.2), or up to eight analyzers can be
connected using COM2 configured for RS-485 operation (contact the factory for further
information). A third option is to use a code-activated switch (CAS), which can connect
typically between 2 and 16 analyzers to one communications hub. Contact T-API sales for
more information on CAS systems.
When equipped with the optional Ethernet interface (Section 5.8.3), the analyzer can be
connected to any standard 10BaseT Ethernet network via low-cost network hubs, switches
or routers. The interface operates as a standard TCP/IP device on port 3000. This allows a
remote computer to connect through the internet to the analyzer using APIcom, terminal
emulators or other programs.
6.9.1. Analyzer ID
The first entry in the COMM menu is for configuration of the analyzer ID number, a
numerical value of up to 4 digits. As a factory default, the M200E is configured with ID
number “200”. The ID number is only important if more than one analyzer is connected to
the same communications channel (e.g., a multi-drop setup), in which case each analyzer
needs to be addressed with a unique ID number. Different models of T-API analyzers have
different ID numbers, but if two identical models are used on one channel (for example, two
M200E instruments), the ID of one instrument needs to be changed. The ID can also be
used for internal identification of same model analyzers in different locations.
For the Hessen protocol (a configuration option listed in Table 0-17 and briefly described in
Section ), the M9110EH assigns different numbers to identify its reported gases. When
this protocol is enabled, the analyzer behaves and reports as three separate instruments,
one for each gas.
6.9.10
6.9.2. COM Port Default Settings
As received from the factory, the analyzer is set up to emulate a DCE or modem, with pin 3
of the DB-9 connector designated for receiving data and pin 2 designated for sending data.
• COM1: RS-232 (fixed), DB-9 male connector.
• Baud rate: 19200 bits per second (baud).
• Data Bits: 8 data bits with 1 stop bit, no start bit.
• Parity: None.
• COM2: RS-232 (configurable), DB-9 female connector.
• Baud rate: 115000 bits per second (baud).
• Data Bits: 8 data bits with 1 stop bit, no start bit.
• Parity: None.
M9110EH Rev 0 79
Operating Instructions Model 9110EH Instruction Manual
CAUTION
Cables that appear to be compatible because of matching connectors may incorpo-
rate internal wiring that make the link inoperable. Check cables acquired from
sources other than T-API for pin assignments before using.
6.9.3. COM Port Cable Connections
There are two DB-9 connectors on the M9110EH rear panel. COM1 is a male connector, COM2
a female connector (Table 0-16 lists pin assignments). T-API offers two mating cables, one
of which should be applicable for your use.
• Part number WR000077, a DB-9 female to DB-9 female cable, 6 feet long. Allows
connection of COM1 with the serial port of most personal computers. Also available
as Option 60 (Section 5.8.1).
• Part number WR0000024, a DB-9 female to DB-25 male cable. Allows connection to
the most common styles of modems (e.g. Hayes-compatible) and code activated
switches.
Both cables are configured with straight-through wiring and should require no additional
adapters.
To assist in properly connecting the serial ports to either a computer or a modem, there are
activity indicators just above each COM port. When power is applied to the analyzer, the red
LED should be illuminated. If this LED is dark, it indicates a communications error between
serial port and CPU.
Once a cable is connected between the analyzer and a computer or modem, both the red
and green LEDs should be on. If not, COM1 can be switched between DTE and DCE modes
using a small switch on the rear panel to exchange the receive and transmit lines
(emulating a cross-over or null-modem cable). If both LEDs are still not illuminated, check
the cable for proper wiring. For COM2 it may be necessary to install a null-modem cable
(contact customer service for information).
6.9.4. COM2 Configuration
As delivered from the factory, COM2 is configured for RS-232 communications. This port
can be re-configured for operation as a non-isolated, half-duplex RS-485 port with a 150 Ω
termination resistor (Table 0-18 shows the pin assignments of the DB-9 connector).
For RS-485 operation, jumper JP3 on the CPU board should be installed and switch 6 of
SW1 should be set to the ON position. For RS-232, remove the jumper and set the switch to
OFF (default). JP3 is just to the right of the third connector from the left on the top of the
CPU board (as seen from the inside of the analyzer). SW1 is in the middle of the CPU board
between disk-on-chip and BIOS. For non-terminated RS-485 operation, remove the jumper
on JP3 but leave switch 6 in the ON position. Refer to Figure 3-7 to locate the CPU board.

6.9.5. DTE and DCE Communication
RS-232 was developed for allowing communications between data terminal equipment
(DTE) and data communication equipment (DCE). Basic terminals always fall into the DTE
category whereas modems are always considered DCE devices. The difference between the
two is the pin assignment of the Data Receive and Data Transmit functions. DTE devices
receive data on pin 2 and transmit data on pin 3, DCE devices receive data on pin 3 and
transmit data on pin 2.
To allow the analyzer to be used with terminals (DTE), modems (DCE) and computers
(which can be either), a switch mounted below the serial ports on the rear panel allows the
user to switch between the two functions (for COM1 only).
6.9.6. COM Port Communication Modes
Each of the analyzer’s serial ports can be configured to operate in a number of different
modes, which are listed in Table 0-17 and which can be combined by adding the Mode ID
numbers. For example, quiet mode, computer mode and internet-enabled mode would carry
a combined mode ID of 11, the standard configuration for Ethernet functionality on the
M9110EH COM2 port. Note that each COM port needs to be configured independently.

6.9.9. Ethernet Port Configuration
The optional Ethernet port (Section 5.8.3) communicates with the analyzer through the
COM2 serial port. Refer to Figure 3-2 and Figure 5-3 for location of this option. The Ethernet
board has two operational modes:
• Pass-through mode: This is the normal operation mode in which the board actively
passes data between the RS-232 port and the RJ-45 connector on the analyzer’s rear
panel. This enables all remote commands to be passed to the analyzer.
• Configuration mode: The board stops passing data and is ready to accept and store
configuration parameters and firmware upgrades. The use of a terminal window or
separate configuration program is needed for these low-level configuration changes.
The iChip configuration utility is available at http://www.teledyne-api.com/software/
and provides a convenient, graphical user interface, which runs only on Microsoft
Windows
using the
TM
operating systems. All commands can also be issued via Terminal window
AT+i
protocol. Instructions for
AT+i
commands are also available at the
website along with other pertinent information.
The Ethernet board has four LEDs that are visible on the rear panel of the analyzer,
indicating its current operating status (Table 0-18).
Table 0-18: Ethernet Status Indicators
LED Function
LNK (green) ON when connection to the LAN is valid.
ACT (yellow) Flickers on any activity on the LAN.
TA (green) Flickers when the RS-232 port is transmitting data.

Operating Instructions Model 9110EH Instruction Manual
Ethernet and is used to set configuration parameters that enable the Ethernet card to
communicate with your local area network. To perform this configuration, you will need to
get the following information from your network administrator:
• Gateway IP address, typically a string of numbers with four packets of 1 to 3
numbers each:
nnn.nnn.nnn.nnn
, for example:
192.168.76.1
.
• Instrument IP address, typically a string of numbers very similar to the Gateway IP
address, for example:
192.168.76.55
. Note that this instrument IP address must
be a static address and cannot be a dynamic IP address. DHCP and analyzer host
names are not supported at this time.
• Subnet Mask, typically a string of numbers such as
255.255.252.0
.
• The communications port number is set to 3000 by default and should not be
changed.
The following procedures assume that the Ethernet card is already installed in your
analyzer. If you are retro-fitting the analyzer with an Ethernet Option 63, please make sure
to enable the internet option as described in Section 6.9.6 and set the baud rate to 115000
as described in Section 6.9.7. Refer to the installation instructions of that option for more
information.
Once Ethernet is enabled for the COM2 port, the first step in configuring the Ethernet option
is to set the card from pass-through mode to configuration mode, so that TCP/IP parameters can be edited.
