IntroductionTeledyne API – Model T300/T300M CO Analyzer

1. INTRODUCTION, FEATURES AND OPTIONS

This section provides an overview of the Model GFC7001T or GFC7001TM Analyzer,
its features and its options, followed by a description of how this user manual is
arranged.

1.1. GFC7001T FAMILY OVERVIEW

The family includes the GFC7001T and the GFC7001TM Gas Filter Correlation Carbon
Monoxide Analyzer. The GFC7001T family of analyzers is a microprocessor-controlled
analyzer that determines the concentration of carbon monoxide (CO) in a sample gas
drawn through the instrument. It uses a method based on the Beer-Lambert law, an
empirical relationship that relates the absorption of light to the properties of the material
through which the light is traveling over a defined distance. In this case the light is
infrared radiation (IR) traveling through a sample chamber filled with gas bearing a
varying concentration of CO.

The GFC7001T/GFC7001TM uses Gas Filter Correlation (GFC) to overcome the
interfering effects of various other gases (such as water vapor) that also absorb IR. The
analyzer passes the IR beam through a spinning wheel made up of two separate

chambers: one containing a high concentration of CO known as the reference, and the
other containing a neutral gas known as the measure. The concentration of CO in the

sample chamber is computed by taking the ratio of the instantaneous measure and
reference values and then compensating the ratio for sample temperature and pressure.

The GFC7001T/GFC7001TM 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 serial port or Ethernet port 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.

3.3.1.3. CONNECTING ANALOG OUTPUTS

The GFC7001T is equipped with several analog output channels accessible through a
connector on the back panel of the instrument. The standard configuration for these
outputs is mVDC. An optional current loop output is available for each.

When the instrument is in its default configuration, channels A1 and A2 output a signal

that is proportional to the CO concentration of the sample gas. Either can be used for
connecting the analog output signal to a chart recorder or for interfacing with a
datalogger.

Output A3 is only used on the GFC7001T/GFC7001TM if the optional CO

is installed.

Channel A4 is special. It can be set by the user (see Section 5.9.8.1) to output any one
of the parameters accessible through the <TST TST> buttons of the units sample

display.

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.

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 connections
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.

Figure 3-10 provides installation instructions and illustrates a sample combination of
one current output and two voltage outputs configuration. Following Figure 3-10 are
instructions for converting current loop analog outputs to standard 0-to-5 VDC outputs.
Information on calibrating or adjusting these outputs can be found in Section 5.9.3.7

CAUTION – AVOID INVALIDATING WARRANTY

Servicing or handling of circuit components requires electrostatic
discharge protection, i.e. ESD grounding straps, mats and containers.
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.

Figure 3-10: Current Loop Option Installed on Motherboard

CONVERTING CURRENT LOOP ANALOG OUTPUTS TO STANDARD VOLTAGE
OUTPUTS

To convert an output configured for current loop operation to the standard 0 to 5 VDC
output operation:

1. Turn off power to the analyzer.

2. If a recording device was connected to the output being modified, disconnect it.

3. Remove the top cover.

 Remove the screw located in the top, center of the front panel.
 Remove the screws fastening the top cover to the unit (both sides).
 Slide the cover back and lift straight up.

4. Remove the screw holding the current loop option to the motherboard.

5. Disconnect the current loop option PCA from the appropriate connector on the
motherboard (see Figure 3-10).

6. Each connector, J19 and J23, requires two shunts. Place one shunt on the two left­most pins and the second shunt on the two pins next to it (see Figure 3-10).

7. Reattach the top case to the analyzer.

 The analyzer is now ready to have a voltage-sensing, recording device

attached to that output.

8. Calibrate the analog output as described in Section 5.9.3.2.

Teledyne Analytical Instruments 47

Getting StartedTeledyne API – Model T300/T300M CO Analyzer

3.3.1.5. CONNECTING THE STATUS OUTPUTS

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 D.

ATTENTION

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 status outputs are accessed via a 12-pin connector on the analyzer’s rear panel
labeled STATUS (see Figure 3-4). Pin-outs for this connector are:

3.3.1.6. CONNECTING THE CONTROL INPUTS

To remotely activate the zero and span calibration modes, several digital control inputs

are provided through 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, if full isolation is
required, an external 5 VDC power supply should be used.

3.3.1.7. CONCENTRATION ALARM RELAY (OPTION 61) STANDARD

CONFIGURATION

The concentration alarm option is comprised of 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 TAI instruments. Each relay has 3 pins:
Normally Open (NO), Common (C), and Normally Closed (NC).

Figure 3-13: 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 and you can record this with a data logger or other recording device.

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
GFC7001TM instrument can monitor both CO & CO

gas. The software is flexible

2

enough to allow you to configure the alarms so that you can have 2 alarm levels for each
gas.

gasses.

A more likely configuration for this would be to put one gas on the “Alarm 1” relay &
the other gas on the “Alarm 2” relay.

3.3.1.8. CONCENTRATION ALARM RELAY (OPTION 61) AIR PRODUCTS
CONFIGURATION

In the Air Products configuration, the 4 relay alarm outputs (AL1-AL4) on the rear panel
are configured differently..

 AL1 is for “system okay”,
 AL2 is for “high range status”
 AL3 is for “zero calibration status”
 AL4 is not used

The AL1 relay is energized when the system is okay and de-energized when the system
has a fault. The AL2 relay is energized when the high auto-range is in use and and AL3
relays energize when the the instrument is in zero calibration mode.

Also, in the Air Products configuration, an additional control input is available on this
instrument. Control input “C” is used to select the range for remote calibration. When
input C is low, the instrument selects high range during contact closure calibration. See
Section 6.15.12.

3.3.1.9. CONNECTING THE COMMUNICATION INTERFACES

The T-Series analyzers are equipped with connectors for remote communications

interfaces: Ethernet, USB, RS-232, optional RS-232 Multidrop, and optional RS-485.

In addition to using the appropriate cables, each type of communication method must be
configured using the SETUP>COMM menu, Section 6. Although Ethernet is DHCP­enabled by default, it can also be configured manually (Section 6.5.1) to set up a static
IP address, which is the recommended setting when operating the instrument via
Ethernet.

Teledyne Analytical Instruments 52

Getting StartedTeledyne API – Model T300/T300M CO Analyzer

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 access port.
Please see Section 6.5 for description and setup instructions.

For manual configuration, see Section 6.5.1.

For automatic configuration (default), see Section 6.5.2.

USB

CONNECTION

For direct communication between the analyzer and a PC, connect a USB cable between
the analyzer and desktop or laptop USB ports. The baud rate for the analyzer and the
computer must match; you may elect to change one or the other: to view and/or change
the analyzer’s baud rate, see Section 6.2.2.

Note If this option is installed, the COM2 port cannot be used for anything

other than Multidrop communication.

For configuration, see 6.6.

IMPORTANT

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.

Configuration: Sections 5.7 and 6.3.

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

RS-232 MULTIDROP OPTION CONNECTION

When the RS-232 Multidrop option is installed, connection adjustments and
configuration through the menu system are required. This section provides instructions
for the internal connection adjustments, 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 3-16.
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

3.3.2. PNEUMATIC CONNECTIONS

This section provides not only pneumatic connection information, but also important
information about the gases required for accurate calibration; 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
special messages:

CAUTION

GENERAL SAFETY HAZARD

CARBON MONOXIDE (CO) IS A TOXIC GAS.

Do not vent calibration gas and sample gas into enclosed areas. Obtain
a Material Safety Data Sheet (MSDS) for this material. Read and
rigorously follow the safety guidelines described there.

CAUTION

GENERAL SAFETY HAZARD

Sample and calibration gases should only come into contact with PTFE
(Teflon), FEP, glass, stainless steel or brass.

It is important to conform to all safety requirements regarding exposure
to CO.

Teledyne Analytical Instruments 59

Getting StartedTeledyne API – Model T300/T300M CO Analyzer

ATTENTION

COULD DAMAGE INSTRUMENT AND VOID WARRANTY

Maximum Pressure:

Ideally the maximum pressure of any gas at the sample inlet should
equal ambient atmospheric pressure and should NEVER exceed

1.5 in-hg above ambient pressure.

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.

IMPORTANT

Run a leak check once the appropriate pneumatic connections have

been made; check all pneumatic fittings for leaks using the
procedures defined in Section 11.3.2.

See Figure 3-4 and Table 3-3 for the location and descriptions of the various pneumatic
inlets/outlets referenced in this section.

Leak Check

Note: Depending on the application, some instruments may include an internal pump. Refer

to any addendum that may accompany this manual for information pertaining to
custom configurations.

3.3.2.10. CALIBRATION GASES

Zero air and span gas are required for accurate calibration.

Z

ERO AIR

Zero air is a gas that is similar in chemical composition to the earth’s atmosphere but
scrubbed of all components that might affect the analyzer’s readings, in this case CO
and water vapor. If your analyzer is equipped with an Internal Zero Span (IZS) or an
external zero air scrubber option, it is capable of creating zero air.

If the analyzer is NOT equipped with the optional CO
scrubbed of CO

as well, as this gas can also have an interfering effect on CO

2

measurements.

For analyzers without an IZS or external zero air scrubber option, a zero air generator
such as the TAI Model T701 can be used.

PAN GAS

S

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 the case of
CO measurements made with the GFC7001T or GFC7001TM Analyzer, it is
recommended that you use a span gas with a CO concentration equal to 80-90% of the
measurement range for your application.

EXAMPLE: If the application is to measure between 0 ppm and 500 ppb, an appropriate
span gas concentration would be 400-450 ppb CO in N

Cylinders of calibrated CO gas traceable to NIST-Standard Reference Material
specifications (also referred to as SRMs or EPA protocol calibration gases) are
commercially available. Table 3-12 lists specific NIST-SRM reference numbers for

SPAN GAS FOR MULTIPOINT CALIBRATION

Some applications, such as EPA monitoring, require a multipoint calibration procedure
where span gases of different concentrations are needed. We recommend using a bottle
of calibrated CO gas of higher concentration in conjunction with a gas dilution calibrator
such as a TAI’s T700. This type of calibrator precisely mixes a high concentration gas

Teledyne Analytical Instruments 71

with zero air (both supplied externally) to accurately produce span gas of the correct
concentration. Linearity profiles can be automated with this model and run unattended
over night.

IMPORTANT

3.4.1. STARTUP

3.4.2. WARNING MESSAGES

IMPACT ON READINGS OR DATA
The analyzer’s cover must be installed to ensure that the temperatures of
the GFC Wheel and absorption cell assemblies are properly controlled.

If you are unfamiliar with the GFC7001T/GFC7001TM theory of operation, we
recommend that you read Section 13. For information on navigating the analyzer’s
software menus, see the menu trees described in Appendix A.

After the electrical and pneumatic connections are made, an initial functional check is in
order. Turn on the instrument. The exhaust fan should start immediately. The display
will briefly show a momentary splash screen of the TAI logo and other information
during the initialization process while the CPU loads the operating system, the firmware
and the configuration data at the start of initialization.

The analyzer should automatically switch to Sample Mode after completing the boot-up
sequence and start monitoring CO gas. However, there is an approximately one hour
warm-up period before reliable gas measurements can be taken. During the warm-up
period, the front panel display may show messages in the Parameters field.

Because internal temperatures and other conditions may be outside the specified limits
during the analyzer’s warm-up period, the software will suppress most warning
conditions for 30 minutes after power up. If warning messages persist after the 60
minutes warm-up period is over, investigate their cause using the troubleshooting
guidelines in Section 12.

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 were installed: navigate through
the analyzer’s software menus, see the menu trees described in Appendix A.

Then check to make sure 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 performance problems

with your analyzer (see Section 12.1.2).

 The enclosed Final Test and Validation Data Sheet (P/N 04271) lists these

values as they were before the instrument left the factory.

To view the current values of these parameters press the following control button
sequence on the analyzer’s front panel. Remember that until the unit has completed its
warm-up these parameters may not have stabilized.

Teledyne Analytical Instruments 74

Getting StartedTeledyne API – Model T300/T300M CO Analyzer

3.4.4. INITIAL CALIBRATION

To perform the following calibration you must have sources for zero air and span gas
available for input into the sample port on the back of the analyzer. See Section 3.3.2
for instructions for connecting these gas sources.

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.

If both available DAS parameters for a specific gas type are being reported via the

instruments analog outputs e.g. CONC1 and CONC2 when the DUAL range mode is

activated, separate calibrations should be carried out for each parameter.

 Use the LOW button when calibrating for CONC1 (equivalent to

RANGE1).

 Use the HIGH button when calibrating for CONC2 (equivalent to

RANGE2).

NOTE The following procedure assumes that the instrument does not have any

of the available Valve Options installed. See Section 9.3 for instructions

Teledyne Analytical Instruments 75

Getting StartedTeledyne API – Model T300/T300M CO Analyzer

for calibrating instruments that have valve options.

3.4.4.1. INTERFERENTS FOR CO MEASUREMENTS

It should be noted that the gas filter correlation method for detecting CO is subject to
interference from a number of other gases that absorb IR in a similar fashion to CO.
Most notable of these are water vapor, CO
The GFC7001T/GFC7001TM has been successfully tested for its ability to reject
interference from of these sources, however high concentrations of these gases can
interfere with the instrument’s ability to make low-level CO measurements.

For a more detailed discussion of this topic, see Section 13.2.1.3.

3.4.4.2. INITIAL CALIBRATION PROCEDURE

The following procedure assumes that:
 The instrument DOES NOT have any of the available calibration valve or gas inlet

options installed;

 Cal gas will be supplied through the SAMPLE gas inlet on the back of the analyzer

4. OVERVIEW OF OPERATING MODES

To assist in navigating the analyzer’s software, a series of menu trees can be found 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 GFC7001T/GFC7001TM 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 CO concentration can be viewed on the front panel and output as an
analog voltage from rear panel terminals, calibrations can be performed and TEST
functions and WARNING messages can be examined. If the analyzer is configured to
measure a second gas (e.g. CO along with O
both concentrations.

The second most important operating mode is SETUP mode. This mode is used for
performing certain configuration operations, 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.

4.1. SAMPLE MODE

This is the analyzer’s standard operating mode. In this mode the instrument is analyzing
the gas in the sample chamber, calculating CO concentration and reporting this
information to the user via the front panel display, the analog outputs and, if set up
properly, the RS-232/RS-485/Ethernet/USB ports.

4.1.1. TEST FUNCTIONS

A series of TEST functions is available for viewing at the front panel whenever the
analyzer is at the SAMPLE mode. These parameters provide information about the

present operating status of the instrument and are useful during troubleshooting (refer to
Section 12.1.2). They can also be recorded in one of the DAS channels (refer to Section

7.2) for data analysis. To view the test functions, press one of the <TST TST> buttons
repeatedly in either direction.

The outputs can be configured either at the factory or by the user for full scale outputs of

0.1 VDC, 1VDC, 5VDC or 10VDC.

Additionally, A1, A2 and A3 may be equipped with optional 0-20 mADC current loop

drivers and configured for any current output within that range (e.g. 0-20, 2-20, 4-20,
etc.). The user may also adjust the signal level and scaling of the actual output voltage
or current to match the input requirements of the recorder or datalogger (See Section

5.9.3.9).

In its basic configuration, the A1 and A2 channels output a signal that is proportional to

the CO

concentration of the sample gas. Several modes are available which allow them

to operate independently or be slaved together (See Section 5.4.3).

EXAMPLE:

A1 OUTPUT: Output Signal = 0-5 VDC representing 0-1000 ppm concentration values
A2 OUTPUT: Output Signal = 0 – 10 VDC representing 0-500 ppm concentration

values.

Output A3 is only active if the CO

representing the currently measured CO

or O2 sensor option is installed. In this case a signal

2

or O2 concentration is output on this channel.

The output, labeled A4 is special. It can be set by the user (See Section 5.9.8.1) to
output several of the test functions accessible through the <TST TST> buttons of the

units sample display.

5.4.2. PHYSICAL RANGE VS ANALOG OUTPUT REPORTING
RANGES

Functionally, the GFC7001T Family of CO Analyzers have one hardware PHYSICAL
RANGE that is capable of determining CO concentrations between across a very wide
array of values.

Teledyne Analytical Instruments 95

SetupTeledyne API – Model T300/T300M CO Analyzer

Table 5-1: GFC7001T Family Physical Range by Model

MODEL RANGE

GFC7001T 0 – 1000 ppm

GFC7001TM 0 – 5000 ppm

This architecture improves reliability and accuracy by avoiding the need for extra,
switchable, gain-amplification circuitry. Once properly calibrated, the analyzer’s front
panel will accurately report concentrations along the entire span of its physical range.

Because many applications use only a small part of the analyzer’s full physical range,
this can create data resolution problems for most analog recording devices. For
example, in an application where an GFC7001T is being used to measure an expected
concentration of typically less than 50 ppm CO, the full scale of expected values is only
4% of the instrument’s full 1000 ppm measurement range. Unmodified, the
corresponding output signal would also be recorded across only 2.5% of the range of the
recording device.

The GFC7001T/GFC7001TM Analyzers solve this problem by allowing the user to
select a scaled reporting range for the analog outputs that only includes that portion of
the physical range relevant to the specific application.

Only this REPORTING RANGE of the analog outputs is scaled; the physical range of
the analyzer and the readings displayed on the front panel remain unaltered.

Note Neither the DAS values stored in the CPU’s memory nor the concentration

values reported on the front panel are affected by the settings chosen for
the reporting range(s) of the instrument.

5.4.3. REPORTING RANGE MODES: SINGLE, DUAL, AUTO RANGES

The GFC7001T/GFC7001TM provides three analog output range modes to choose from.

 Single range (SNGL) mode sets a single maximum range for the analog output. If

single range is selected both outputs are slaved together and will represent the same
measurement span (e.g. 0-50 ppm), however their electronic signal levels may be
configured for different ranges (e.g. 0-10 VDC vs. 0-.1 VDC).

 Dual range (DUAL) allows the A1 and A2 outputs to be configured with different

measurement spans as well as separate electronic signal levels.

 Auto range (AUTO) mode gives the analyzer to ability to output data via a low

range and high range. When this mode is selected the analyzer will automatically
switch between the two ranges dynamically as the concentration value fluctuates.

Range status is also output via the external digital I/O status outputs (See Section

3.3.1.4).

To select the Analog Output Range Type press:

Teledyne Analytical Instruments 96

SetupTeledyne API – Model T300/T300M CO Analyzer

Upper span limit setting for the individual range modes are shared. Resetting the span
limit in one mode also resets the span limit for the corresponding range in the other
modes as follows:

SNGL DUAL AUTO
Range  Range1  Low Range
Range2  High Range

Teledyne Analytical Instruments 97

SetupTeledyne API – Model T300/T300M CO Analyzer

5.4.3.1. SINGLE RANGE MODE (SNGL)

Single Range Mode (SNGL) is the default reporting range mode for the analyzer.

When the single range mode is selected (SNGL), all analog CO concentration outputs
(A1 and A2) are slaved together and set to the same reporting range limits (e.g. 500.0

ppb). The span limit of this reporting range can be set to any value within the physical
range of the analyzer.

Although both outputs share the same concentration reporting range, the electronic
signal ranges of the analog outputs may still be configured for different values (e.g. 0-5
VDC, 0-10 VDC, etc; see Section 5.9.3.1)

To select SNGL range mode and to set the upper limit of the range, press:

Teledyne Analytical Instruments 98

SetupTeledyne API – Model T300/T300M CO Analyzer

5.4.3.2. DUAL RANGE MODE (DUAL)

Selecting the DUAL range mode allows the A1 and A2 outputs to be configured with

different reporting ranges. The analyzer software calls these two ranges low and high.

 The LOW range setting corresponds with the analog output labeled A1 on the rear

panel of the instrument.

 The HIGH range setting corresponds with the A2 output.

While the software names these two ranges low and high, they do not have to be
configured that way. For example: The low range can be set for a span of 0-1000 ppm
while the high range is set for 0-500 ppm.

In DUAL range mode the RANGE test function displayed on the front panel will be

replaced by two separate functions:

 RANGE1: The range setting for the A1 output.
 RANGE2: The range setting for the A2 output.

To select the DUAL range mode press following buttonstroke sequence

.

When the instrument’s range mode is set to DUAL, the concentration field in the upper
right hand corner of the display alternates between displaying the low range value and
the high range value. The concentration currently being displayed is identified as

follows: C1= LOW (or A1) and C2 = HIGH (or A2).
