Model 9110TH NOx Analyzer Introduction
1. INTRODUCTION, FEATURES AND OPTIONS
1.1. OVERVIEW
The Model 9110T Nitrogen Oxides Analyzer uses chemiluminescence detection, coupled with
state-of-the-art microprocessor technology to provide the sensitivity, stability and ease of use
needed for ambient or dilution CEM monitoring requirements of nitric oxide (NO), nitrogen
dioxide (NO2) and the total nitrogen oxides (NOx). The instrument:
Calculates the amount of NO present by measuring the amount of chemiluminescence given off
when the sample gas is exposed to ozone (O3).
Uses a catalytic-reactive converter to convert any NO2 in the sample gas to NO, which is then
measured as above (including the original NO in the sample gas) and reported as NOx.
Since the density of the sample gas effects the brightness of the chemiluminescence reaction, the 9110T
software compensates for temperature and pressure changes.
Stability is further enhanced by an Auto-Zero feature which periodically redirects the gas flow through
the analyzer so that no chemiluminescence reaction is present in the sample chamber. The analyzer
measures this “dark” condition and uses the results as an offset, which is subtracted from the sensor
readings recorded while the instrument is measuring NO and NO
and dependable performance under the harshest operating conditions.
. The result gives a sensitive, accurate,
X
The 9110T analyzer’s multi-tasking software gives the ability to track and report a large number of
operational parameters in real time. These readings are compared to diagnostic limits kept in the
analyzers memory and should any fall outside of those limits the analyzer issues automatic warnings.
Built-in data acquisition capability, using the analyzer's internal memory, allows the logging of multiple
parameters including averaged or instantaneous concentration values, calibration data, and operating
parameters such as pressure and flow rate. Stored data are easily retrieved through the rear panel serial
or Ethernet ports via our APICOM software or from the front panel, allowing operators to perform
predictive diagnostics and enhanced data analysis by tracking parameter trends. Multiple averaging
periods of one minute to 365 days are available for over a period of one year.
1.2. FEATURES
Some of the other exceptional features of your 9110T Nitrogen Oxides Analyzer are:
Ranges, 0-50 ppb to 0-20 ppm, user selectable
Independent ranges and auto ranging
Large, vivid, and durable graphics display with touch screen interface
Microprocessor controlled for versatility
Multi-tasking software to allow viewing test variables while operating
Continuous self checking with alarms

The 9110T is equipped with several analog output channels accessible through a connector on the back
panel of the instrument.
Output channels A1, A2 and A3 are assigned to the NO
, NO and NO2 concentration signals of the
x
analyzer.
The default analog output voltage setting of these channels is 0 to 5 VDC with a reporting
range of 0 to 500 ppb.
An optional Current Loop output is available for each.
The output labeled A4 is special. It can be set by the user to output any one a variety of diagnostic test
functions (see Section 5.9.4).
The default analog output voltage setting of these channels is also 0 to 5 VDC.
See Section 5.9.4 for a list of available functions and their associated reporting range.
There is no optional Current Loop output available for Channel A4.
To access these signals attach a strip chart recorder and/or data-logger to the appropriate analog output
connections on the rear panel of the analyzer. Pin-outs for the analog output connector are:

3.3.1.4. Current Loop Analog Outputs (Option 41) Setup
If your analyzer had this option installed at the factory, there are no further connectons to be made.
Otherwise, it can be installed as a retrofit for each of the analog outputs of the analyzer . 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.

The status outputs report analyzer conditions via optically isolated NPN transistors, which sink up to 50
mA of DC current. These outputs can be used interface with devices that accept logic-level digital
inputs, such as Programmable Logic Controllers (PLCs). Each Status bit is an open collector output that
can withstand up to 40 VDC. All of the emitters of these transistors are tied together and available at pin
D.
ATTENTION
The status outputs are accessed via a 12-pin connector on the analyzer’s rear panel labeled STATUS
(Figure 3-4). Pin-outs for this connector are:
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Most PLC’s have internal provisions for limiting the current that the input
will draw from an external device. When connecting to a unit that does
not have this feature, an external dropping resistor must be used to limit
the current through the transistor output to less than 50 mA. At 50 mA,
the transistor will drop approximately 1.2V from its collector to emitter.

The analyzer is equipped with three digital control inputs that can be used to remotely activate the zero
and span calibration modes (see Section 9.1.2.4). Access to these inputs is provided via a 10-pin
connector labeled CONTROL IN on the analyzer’s rear panel.
There are two methods for energizing the Control Inputs. The internal +5V available from the pin
labeled “+” is the most convenient method however, to ensure that these inputs are truly isolated; a

3.3.1.7. Concentration Alarm Relay (Option 61)
The TAI “E” series analyzers have an option for four (4) “dry contact” relays on the rear panel of the
instrument. This relay option is different from and in addition to the “Contact Closures” that come
standard on all TAPI instruments. The relays have 3 pins that have connections on the rear panel (refer
Figure 3-12). They are a Common (C), a Normally Open (NO), & a Normally Closed (NC) pin.
Figure 3-12: Concentration Alarm Relay
Alarm 1 “System OK 2”
Alarm 2 “Conc 1”
Alarm 3 “Conc 2”
Alarm 4 “Range Bit”
“ALARM 1” RELAY
Alarm 1 which is “System OK 2” (system OK 1, is the status bit) is in the energized state when the
instrument is “OK” & there are no warnings. If there is a warning active or if the instrument is put into
the “DIAG” mode, Alarm 1 will change states. This alarm has “reverse logic” meaning that if you put a
meter across the Common & Normally Closed pins on the connector you will find that it is OPEN when
the instrument is OK. This is so that if the instrument should turn off or lose power, it will change states
& you can record this with a data logger or other recording device.
“ALARM 2” RELAY & “ALARM 3” RELAY
The “Alarm 2 Relay” on the rear panel, is associated with the “Concentration Alarm 1” set point in the
software & the “Alarm 3 Relay” on the rear panel is associated with the “Concentration Alarm 2” set
point in the software.
Alarm 2 Relay NO Alarm 1 = xxx PPM
Teledyne Analytical Instruments 47
Model 9110T NOx Analyzer Getting Started
Alarm 3 Relay NO2 Alarm 2 = xxx PPM
Alarm 2 Relay NOX Alarm 1 = xxx PPM
Alarm 3 Relay NOX Alarm 2 = xxx PPM
The Alarm 2 Relay will be turned on any time the concentration set-point is exceeded & will return to its
normal state when the concentration value goes back below the concentration set-point.
Even though the relay on the rear panel is a NON-Latching alarm & resets when the concentration goes
back below the alarm set point, the warning on the front panel of the instrument will remain latched until
it is cleared. You can clear the warning on the front panel by either pushing the CLR button on the front
panel or through the serial port.
In instruments that sample more than one gas type, there could be more than one gas type triggering the
Concentration 1 Alarm (“Alarm 2” Relay). For example, the 9110T instrument can monitor both NO &
NO
gas. The software for this instrument is flexible enough to allow you to configure the alarms so that
2
you can have 2 alarm levels for each gas.
NO Alarm 1 = 20 PPM
In this example, NO Alarm 1 & NO2 Alarm 1 will both be associated with the “Alarm 2” relay on the
rear panel. This allows you do have multiple alarm levels for individual gases.
A more likely configuration for this would be to put one gas on the “Alarm 1” relay and the other gas on
the “Alarm 2” relay.

NO Alarm 2 = 100 PPM
NO2 Alarm 1 = 20 PPM

This relay is connected to the “range bit”. If the instrument is configured for “Auto Range” and the
instrument goes up into the high range, it will turn this relay on.
3.3.1.8. Connecting the Communications Interfaces
The T-Series analyzers are equipped with connectors for remote communications interfaces: Ethernet,
USB, RS-232, RS-232 Multidrop and RS-485 (each described here). In addition to using the
Teledyne Analytical Instruments 48
Model 9110TH NOx Analyzer Getting Started
appropriate cables, each type of communication method, must be configured using the SETUP>COMM
menu (see Sections 5.7 and 6).
ETHERNET CONNECTION
For network or Internet communication with the analyzer, connect an Ethernet cable from the analyzer’s
rear panel Ethernet interface connector to an Ethernet port. Although the analyzer is shipped with DHCP
enabled by default (Section 6.5.2), it should be manually assigned a static IP address.
Configuration: (manual, i.e., static) Section 6.5.1.
USB CONNECTION
The USB option can be used for direct communication between the analyzer and a PC; connect a USB
cable between the analyzer and computer USB ports. Baud rates must match: check the baud rate on
either the computer or the instrument and change the other to match (see Section 6.2.2). This USB
connection can only be used when the COM2 port is not in use except for RS-232 Multidrop
communication.
Configuration: Section 6.6.
Note If this option is installed, the rear panel COM2 port cannot be used for
anything other than Multidrop communication.
RS-232 CONNECTION
For RS-232 communications with data terminal equipment (DTE) or with data communication
equipment (DCE) connect either a DB9-female-to-DB9-female cable (TAI part number WR000077) or a
DB9-female-to-DB25-male cable (Option 60A, Section 1.4), as applicable, from the analyzer’s rear
panel RS-232 port to the device. Adjust the DCE-DTE switch (Figure 3-4) to select DTE or DCE as
appropriate (Section 6.1).
Configuration: Section 6.3 and Section 6.7.2 (for Hessen protocol).
IMPORTANT
IMPACT ON READINGS OR DATA
Cables that appear to be compatible because of matching connectors
may incorporate internal wiring that makes the link inoperable. Check
cables acquired from sources other than TAI for pin assignments (Figure
3-13) before using.

TAI offers two mating cables, one of which should be applicable for your use.
P/N WR000077, a DB-9 female to DB-9 female cable, 6 feet long. Allows connection of the
serial ports of most personal computers.
P/N WR000024, 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.
Note Cables that appear to be compatible because of matching connectors
may incorporate internal wiring that makes the link inoperable. Check
cables acquired from sources other than TAI for pin assignments before
using.
To assist in properly connecting the serial ports to either a computer or a modem, there are activity
indicators just above the RS-232 port. Once a cable is connected between the analyzer and a computer
or modem, both the red and green LEDs should be on.
If the lights are not lit, locate the small switch on the rear panel to switch it between DTE
and DCE modes.
If both LEDs are still not illuminated, ensure that the cable properly constructed.
Received from the factory, the analyzer is set up to emulate an RS-232 DCE device.

then for external connections, and ends with instructions for menu-driven configuration.
Note Because the RS-232 Multidrop option uses both the RS232 and COM2
DB9 connectors on the analyzer’s rear panel to connect the chain of
instruments, COM2 port is no longer available for separate RS-232 or
RS-485 operation.
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Printed Circuit Assemblies (PCAs) are sensitive to electro-static
discharges too small to be felt by the human nervous system. Failure to
use ESD protection when working with electronic assemblies will void
the instrument warranty. Refer to Section 14 for more information on
preventing ESD damage.
In each instrument with the Multidrop option there is a shunt jumpering two pins on the serial Multidrop
and LVDS printed circuit assembly (PCA), as shown in Figure 3-15. This shunt must be removed from
all instruments except that designated as last in the multidrop chain, which must remain terminated. This
requires powering off and opening each instrument and making the following adjustments:
1. With NO power to the instrument, remove its top cover and lay the rear panel open
for access to the Multidrop/LVDS PCA, which is seated on the CPU.
2. On the Multidrop/LVDS PCA’s JP2 connector, remove the shunt that jumpers Pins
21 22 as indicated in. (Do this for all but the last instrument in the chain where
the shunt should remain at Pins 21 22).
3. Check that the following cable connections are made in all instruments (again refer
to Figure 3-15):

remove the shunt between Pins 21 22 of JP2 on the Multidrop/LVDS PCA in the
instrument that was previously the last instrument in the chain.)
4. Close the instrument.
5. Referring to Figure 3-16 use straight-through DB9 male DB9 female cables to
interconnect the host RS232 port to the first analyzer’s RS232 port; then from the
first analyzer’s COM2 port to the second analyzer’s RS232 port; from the second
analyzer’s COM2 port to the third analyzer’s RS232 port, etc., connecting in this
fashion up to eight analyzers, subject to the distance limitations of the RS-232
standard.
6. On the rear panel of each analyzer, adjust the DCE DTE switch so that the green
and the red LEDs (RX and TX) of the COM1 connector (labeled RS232) are both
lit. (Ensure you are using the correct RS-232 cables internally wired specifically for
RS-232 communication; see Table 1-1, “Communication Cables” and Section
3.3.1.8: Connecting the Communications Interfaces, “RS-232 Connection”).

As delivered from the factory, COM2 is configured for RS-232 communications. This port can be
reconfigured for operation as a non-isolated, half-duplex RS-485 port. Using COM2 for RS-485
communication will disable the USB port. To reconfigure this port for RS-485 communication, please
contact the factory.
3.3.2. PNEUMATIC CONNECTIONS
This section provides not only pneumatic connection information, but also important information about
the gases required for accurate calibration (Section 3.3.2.1); it also illustrates the pneumatic layouts for
the analyzer in its basic configuration and with options.
Before making the pneumatic connections, carefully note the following cautionary and additional
messages:
Do not vent calibration gas or sample gas into enclosed areas.
CAUTION
GENERAL SAFETY HAZARD
IMPORTANT
CAUTION – GENERAL SAFETY HAZARD
In units with a permeation tube option installed, vacuum pump must be
connected and powered on to maintain constant gas flow though the
analyzer at all times. Insufficient gas flow allows gas to build up to levels
that will contaminate the instrument or present a safety hazard to
personnel.
Remove permeation tube when taking analyzer out of operation, and store
in sealed container (use original container that tube was shipped in).
(See Figure 3-6 for location and Section 11.3.6 for instructions on how to
remove the perm tube when the unit is not in operation).
IMPACT ON READINGS OR DATA
Sample and calibration gases should only come into contact with PTFE
tubing.

Model 9110T NOx Analyzer Getting Started
ATTENTION
IMPORTANT
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Venting Pressurized Gas:
In applications where any gas (span gas, zero air supply, sample gas) is
received from a pressurized manifold, a vent must be provided to equalize
the gas with ambient atmospheric pressure before it enters the analyzer to
ensure that the gases input do not exceed the maximum inlet pressure of
the analyzer, as well as to prevent back diffusion and pressure effects.
These vents should be:
• at least 0.2m long
• no more than 2m long
• vented outside the shelter or immediate area surrounding the instrument.
Dust Plugs:
Remove dust plugs from rear panel exhaust and supply line fittings before
powering on/operating instrument. These plugs should be kept for reuse in
the event of future storage or shipping to prevent debris from entering the
pneumatics.
Leak Check:
Run a leak check once the appropriate pneumatic connections have
been made; check all pneumatic fittings for leaks using the
procedures defined in Section 11.3.12.1.
3.3.2.1. About Zero Air and Calibration (Span) Gas
Zero air and span gas are required for accurate calibration.
Note Zero air and span gases must be supplied at twice the instrument’s
specified gas flow rate. Therefore, the 9110T zero and span gases should
be supplied to their respective inlets in excess of 1000 cc3/min (500
cc3/min x 2).
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.
For the 9110T this means zero air should be devoid of NO, NO
Note Moderate amounts of NH3 and H2O can be removed from the sample gas
stream by installing the optional sample gas dryer/scrubber (see Section
3.3.2.6).
If your application is not a measurement in ambient air, the zero calibration gas should be matched
to the composition of the gas being measured.
, CO2, NH3 or H2O vapor.
2
Teledyne Analytical Instruments 56
Model 9110TH NOx Analyzer Getting Started
Pure nitrogen (N2) could be used as a zero gas for applications where NOX is measured in nitrogen.
If your analyzer is equipped with an external zero air scrubber option, it is capable of creating zero
air from ambient air.
For analyzers without the external zero air scrubber, a zero air generator such as the Teledyne
Model 701 can be used. Please visit the company website for more information.
CALIBRATION (SPAN) GAS
Calibration 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 reporting range. To measure NO
analyzer, 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 NOX in ambient air between 0 ppm and 500 ppb, an appropriate
span gas would be 400 ppb.
If the application is to measure NOX in ambient air between 0 ppm and 1000 ppb, an appropriate
span gas would be 800 ppb.
with the 9110T NO
X

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 the following types of calibrated NOx and NO gas traceable to NIST standards specifications
(also referred to as EPA protocol calibration gases or Standard Reference Materials) are commercially
available.

Zero Air generator (IZS) has a limited accuracy of about ±5%.
While NO2 permeation tubes may be sufficient for informal calibration
checks, they are not approved by the US EPA as calibration sources for
performing actual calibration of the analyzer.
SPAN GAS FOR MULTIPOINT CALIBRATION
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 Teledyne Model 700E. This type of calibrator mixes a high
concentration gas with zero air to accurately produce span gas of the desired concentration. Linearity
profiles can be automated with this model and run unattended overnight.
If a dynamic dilution system such as the Teledyne 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 so that the dynamic dilution system operates in its mid-range and not
at the extremes of its dilution capabilities.
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 9110T analyzer (dilution ratio
of 222, in the mid-range of the system’s capabilities).

In the Model 9110T the permeation tube enclosure is heated to a constant 50° C (10° above the
maximum operating temperature of the instrument) in order to keep the permeation rate constant. A
thermistor measures the actual temperature and reports it to the CPU for control feedback.

NITRIC ACID AND THE CHEMISTRY OF NO2 PERMEATION TUBES
The reaction of H2O with NO2 to form HNO3 (nitric acid) takes place whenever water and NO2 are
present in the same gas mixture. In the 9110T this is mitigated as much as possible by passing the air
supply for the span gas generator through a special dryer, however the permeable membrane of the NO
tube will still allow H

3.4.3. FUNCTIONAL CHECKS
After the analyzer’s components have warmed up for at least 60 minutes, verify that the software
properly supports any hardware options that are installed.
For information on navigating through the analyzer’s software menus, see the menu trees described in
Appendix A.1.
Check to ensure that the analyzer is functioning within allowable operating parameters.
Appendix C includes 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 problems with your analyzer.
The enclosed Final Test and Validation Data sheet (P/N 04409) lists these values before the
instrument left the factory.
To view the current values of these parameters press the following button sequence on the analyzer’s
front panel. Remember until the unit has completed its warm up these parameters may not have
stabilized.
3.4.4. INITIAL CALIBRATION
To perform the following calibration you must have sources for zero air and calibration (span) gas
available for input into the inlet/outlet fittings on the back of the analyzer (see Section 3.3.2.1).
Teledyne Analytical Instruments 77
Model 9110T NOx Analyzer Getting Started
Note A start-up period of 4-5 hours is recommended prior to performing a
calibration on the analyzer.
The method for performing an initial calibration for the 9110T nitrogen oxides analyzer differs slightly
depending on the whether or not any of the available internal zero air or valve options are installed.
See Section 3.4.4.2 for instructions for initial calibration of the 9110T analyzers in their base
configuration.
See Section 9.3 for instructions for initial calibration of 9110T analyzers possessing an optional
Internal Span Gas Generator (OPT 51A).
See Section 9.4 for information regarding setup and calibration of 9110T analyzers with Z/S Valve
options.
If you are using the 9110T analyzer for EPA monitoring, only the calibration method described in
Section 10 should be used.
3.4.4.1. INTERFERENTS FOR NOX, NO AND NO2 MEASUREMENTS
The chemiluminescence method for detecting NOX is subject to interference from a number of sources
including water vapor (H
9110T has been designed to reject most of these interferences.
Ammonia is the most common interferent, which is converted to NO in the analyzer’s NO2 converter
and creates a NO
If the 9110T is installed in an environment with high ammonia, steps should be taken to
remove the interferent from the sample gas before it enters the reaction cell.
TAI offers a sample gas conditioning option to remove ammonia and water vapor (Section
3.3.2.6).

Model 9110TH NOx Analyzer Overview of Operating Modes
4. OVERVIEW OF OPERATING MODES
To assist in navigating the analyzer’s software, a series of menu trees is available for reference in
Appendix A of this manual.
Note Some control buttons on the touch screen do not appear if they are not
applicable to the menu that you’re in, the task that you are performing, the
command you are attempting to send, or to incorrect settings input by the
user. For example, the ENTR button may disappear if you input 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.
The 9110T analyzer software has a variety of operating modes. The most common mode that the
analyzer will be operating in is the SAMPLE mode. In this mode, a continuous read-out of the NO
concentrations can be viewed on the front panel and output as an analog voltage from rear panel
terminals.
x
The second most important operating mode is SETUP mode. This mode is used for
configuring the various sub systems of the analyzer such as for the DAS system, the reporting ranges,
or the serial (RS-232 / RS-485 / Ethernet) communication channels. The SETUP mode is also used for
performing various diagnostic tests during troubleshooting.
Figure 4-1: Front Panel Display
The mode field of the front panel display indicates to the user which operating mode the unit is currently
running.
In addition to SAMPLE and SETUP, other modes the analyzer can be operated in are described in Table

4.2. CALIBRATION MODE
Pressing the CAL button, switches the analyzer into calibration mode. In this mode the user can, in
conjunction with introducing zero or span gases of known concentrations into the analyzer, cause it to
adjust and recalculate the slope (gain) and offset of the its measurement range. This mode is also used to
check the current calibration status of the instrument.
If the instrument includes one of the available zero/span valve options, the SAMPLE mode display will
also include CALZ and CALS buttons. Pressing either of these buttons also puts the instrument into
calibration mode.
The CALZ button is used to initiate a calibration of the analyzer’s zero point using internally
generated zero air.
The CALS button is used to calibrate the span point of the analyzer’s current reporting range using
span gas.
Note It is recommended that this span calibration be performed at 80% of full
scale of the analyzer’s currently selected reporting range.
EXAMPLES:
If the reporting range is set for 0 to 500 ppb, an appropriate span point
would be 400 ppb.
If the of the reporting range is set for 0 to 1000 ppb, an appropriate span
point would be 800 ppb.
Due to the critical importance and complexity, calibration operations are described in detail in other
sections of the manual:
Section 9 details setting up and performing standard calibration operations or checks.
Section 10 details setting up and performing EPA protocol calibrations.
For information on using the automatic calibrations feature (ACAL) in conjunction with the one of the
calibration valve options, see Sections 9.4.3 and 9.5.

To avoid inadvertent adjustments to critical settings, activate calibration
security by enabling password protection in the SETUP – PASS menu

CONFIGURATION
Use the SETUP>RNGE menu to configure output reporting ranges, including scaled reporting ranges to
handle data resolution challenges. This section describes configuration for Single, Dual, and Auto Range
modes.
5.4.1. 9110T PHYSICAL RANGES
The 9110T NOx analyzer measures NOx, NO and NO2 concentrations from 2 to 20,000 ppb.
Electronically the 9110T analyzer converts the 0-5 volt analog signal output by the PMT into a digital
signal with 4096 counts of resolution. Since its measurement range is 0 ppb to 20,000 ppb, this only
allows about 3 ppb per count. While this might be acceptable for high concentration measurements
made in parts per million units (ppm), it is not good enough for lower level NO
overcome this limitation the 9110T is designed with two physical measurement ranges:
A LOW range that measures concentration from 0 ppb to 2,000 ppb with a resolution of 0.27 ppb per
count.
A HIGH range that measures the full 20,000 ppb range of the analyzer.
measurements. To
x
The analyzer’s CPU chooses the appropriate range based on how the user sets up the reporting ranges for
the instruments analog outputs when an analog range is selected with a lower limit between 0 and 2000
ppb the analyzer will utilize its low physical range. When an analog range is in use that has a reporting
range with an upper limit set between 2001 and 20,000 ppb the instrument will operate in its high
physical range.
Once both ranges have been using the same span gas values the analyzer’s front panel will accurately
report concentrations between 0 and 20,000 ppb, seamlessly switching between the low and high
physical ranges regardless of the selected analog reporting range.
5.4.2. 9110T ANALOG OUTPUT REPORTING RANGES
For applications using chart recorders or other analog recording devices, the 9110T's 20,000 ppb
physical range can cause resolution problems. For example, in an application where the expected
concentrations of NO, NO
only 2.5% of the instrument’s 20,000 ppb physical range. The corresponding output signal would then
only be recorded across 2.5% of the range of the recording device.
The 9110T 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. This increases
the reliability and accuracy of the analyzer by avoiding additional gain-amplification circuitry.
Note Only the reporting range of the analog outputs is scaled.
and NOx are typically less than 500 ppb, the full scale of expected values is
2
Both the DAS values stored in the CPU’s memory and the concentration
values reported on the front panel are unaffected by the settings chosen
for the reporting range(s) of the instrument.

5.4.2.1. Analog Output Ranges for NOx, NO and NO2 Concentration
The analyzer has three active analog output signals related to NOx, NO and NO2 concentration,
accessible through a connector on the rear panel.
ANALOG OUT

+ - + - + - + -
Figure 5-1: Analog Output Connector Pin Out
The A1, A2 and A3 channels output a signal that is proportional to the NO
of the sample gas, respectively. The 9110T can be set so that these outputs operate in one of the three
following modes: single range mode, independent range mode, or automatic range mode (Section 5.4.3).
Additionally, the signal levels of outputs A1, A2 and A3 outputs can be:
Configured full scale outputs of: 0 - 0.1 VDC; 0 – 1 VDC; 0 – 5 VDC or; 0 – 10 VDC.

Equipped with optional 0-20 mADC current loop drivers (see Section 3.3.1.4 ) and configured for any
current output within that range analog output (e.g. 0-20 mA, 2-20 mA, 4-20 mA, etc.).
Together these two set of parameters allow the user a great deal of flexibility in how the instrument
reports NOx , NO and NO2 concentration to external devices. For example, Using the IND mode the
following configuration could be created:
A1 OUTPUT: NO
Output Signal = 4 – 20 mA representing 0-1000 ppb concentration values
x
A2 OUTPUT: NO Output Signal = 0 – 10 VDC representing 0-500 ppb concentration values.
A3 OUTPUT: NO
Output Signal = 0 – 5 VDC representing 0-500 ppb concentration values.

The user may also add a signal offset independently to each output (see Section 5.9.3.9) to match the
electronic input requirements of the recorder or data logger to which the output is connected.
IMPORTANT
IMPACT ON READINGS OR DATA
The instrument does not remember upper range limits settings associated
with the individual modes. Changes made to the range limits (e.g. 400 ppb
600 ppb) when in one particular mode will alter the range limit settings
for the other modes.
When switching between reporting range modes, ALWAYS check and
Teledyne Analytical Instruments 97

reset the upper range limits for the new mode selection..
5.4.2.2. Analog Output Reporting Range Default Settings
The default setting for these the reporting ranges of the analog output channels A1, A2 and A3 are:
SNGL mode
0 to 500.0 ppb
0 to 5 VDC
5.4.3. SETUP RNGE MODE
Single range mode (SNGL) reports all three of the NOx gas concentrations using the same reporting
range span (see Section 5.4.3.1).
Independent range mode (IND) allows the NOx, NO and NO2 analog outputs to be set with different
reporting range spans (see Section 5.4.3.2).
Automatic range mode (AUTO) allows the analyzer to automatically switch the reporting range between
two user upper span limits (designated LOW and HIGH) based on the actual concentrations being
measured for each (see Section 5.4.3.3). These are not the same as the analyzer’s low and high physical
ranges.
5.4.3.1. SETUP RNGE MODE SNGL: Configuring the 9110T Analyzer for Single
Range Mode
Note
When the single range mode is selected (SNGL), all analog NO
(A1, A2 and A3) are slaved together and set to the same reporting range limits (e.g. 500.0 ppb). This
reporting range can be set to any value between 100 ppb and 20,000 ppb.
Although all three NO
of the analog outputs may still be configured for different values (e.g. 0-5 VDC, 0-10 VDC, etc; see
