Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
1.3 Principle of Operation
The detection and measurement of Carbon Monoxide in the Model 300M is based on the
absorption of Infra Red (IR) radiation by CO molecules at wavelengths near 4.5 microns. As
illustrated in Figure 1-1, the Model 300M uses a high energy heated element to generate broadband IR light. This light is passed through a rotating Gas Filter Wheel causing the beam to
alternately pass through a gas cell filled with Nitrogen, (the Measure Cell) and a cell filled with
CO/Nitrogen Mixture (the Reference Cell). This alternation occurs at a rate of 30 cycles/second
and causes the beam to be modulated into Reference and Measure pulses. During a Reference
pulse, the CO in the gas filter wheel effectively strips the beam of all IR energy at wavelengths
where CO can absorb. This results in a beam which is unaffected by any CO in the Sample Cell.
During the Measure pulse, the Nitrogen in the filter wheel does not affect the beam which can
subsequently be absorbed by any CO in the sample cell. The Gas Filter wheel also incorporates
an optical chopping mask which superimposes a 180 Cycles/Second Light/Dark modulation on
the IR Beam. This high frequency modulation is used to maximize detector signal-to-noise
performance.
After the gas filter wheel, the IR beam enters the single pass sample cell. The beam then passes
through a band-pass interference filter to limit the light to the wavelengths of interest. Finally,
the beam strikes the detector which is a thermoelectrically cooled solid-state photo-conductor.
This detector, along with its pre-amplifier converts the light signal into a modulated voltage
signal.
The detector output is electronically demodulated to generate two DC voltages, CO MEAS and
CO REF. These voltages are proportional to the light intensity striking the detector during the
Measure pulse and Reference pulse, respectively.

1.5 Installation and Overview
The Model 300M is shipped with the following standard equipment:
1. Power cord
2. Operation manual
CAUTION
To avoid personal injury, always use two persons to
lift and carry the Model 300M.
Upon receiving the Model 300M please do the following:
1. Verify no apparent shipping damage. (If damage has occurred please advise shipper first,
then Teledyne API.)
2. Before operation it is necessary to remove the shipping hold down screws. Remove the
instrument cover, then refer to Figure 1-2 for screw location.
3. When installing the Model 300M, allow a minimum of 4 inches (10 cm) of clearance at the
back of the instrument and 1 inch (2.5 cm) of clearance on each side for proper ventilation.
Also, be sure that the clearance below the chassis is unobstructed by at least the height of the
instrument feet.
4. Connect sample inlet line to the sample port on rear panel.
NOTE
See Figure 1-3 for rear panel pneumatic connections. Sample gas
should only come into contact with PTFE, glass or stainless steel.
Leak check all fittings with soap solution.
CAUTION
Connect the exhaust fitting on the rear panel (see Figure 1-4) to a
suitable vent outside the analyzer area.
5. Connect a recording device to the terminal strip connections on the rear panel (See
Figure 1-3).
6. Connect the power cord to an appropriate power outlet (see the serial number tag for correct
voltage and frequency).
1-6
Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
CAUTION
Check that analyzer is set up for proper voltage and frequency.
CAUTION
Power plug must have ground lug.
7. Turn on the M300M by switching the switch on the lower right corner of the front panel (See
Figure 2-1). The front panel display should light with a sequence of messages, -API M300M - software version number, then a normal display as shown in Figure 2-2.
8. Allow about 30 minutes for the temperatures to come up to their respective set-points, then
press the left most button on the front keyboard to scroll through the TEST values. Compare
these values to those noted during the final factory checkout listed in Table 1-2. The values
observed should closely match the Table 1-2 values.
9. Select the range on which the analyzer will be calibrated.
A. From the SAMPLE menu, press SETUP to enter the SETUP menu. (See Figure 2-2 for
appearance of front panel.)
B. Enter the PASSWORD (818).
C. Press RNGE (RANGE).
D. Press SET.
E. Enter the derived full scale range for analog outputs and press ENTR.
F. Press EXIT 2 times to return to the SAMPLE menu.
10. Adjust the analyzer zero point.
A. Input zero air into the sample port.
B. Press CAL from the SAMPLE menu and enter the password (818).
C. Press ZERO.
D. It usually takes about 5 to 10 minutes for the reading to stabilize near zero. After a stable
reading has been obtained press ENTR. The display should now read 0.0 PPM Carbon
Monoxide.
1-7
Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
NOTE
Repeatedly pressing enter during span/zero calibration does not

11. Adjust the analyzer span point.
A. Input span gas of approximately 80% of the related full scale range concentration from a
known source through the sample port of the analyzer.
B. Go to manual calibration by pressing the CAL button while in the sample mode.
C. Enter the operator password (818).
D. The menu should now show SPAN, CONC, and EXIT. Enter the concentration of the CO
calibration gas by pressing CONC and entering the value from the keyboard.
E. Wait 10 minutes for a stable reading to be attained and then press SPAN, followed by
ENTR. If the SPAN button is not displayed, this means that the analyzer is too far out of
adjustment to do a reliable calibration and thus it is not permitted (see Section 3.1 for
information on the calibration). The operator can exit the manual calibration procedure
only by pressing the EXIT button.

The RS-232 connection is a male, 9-pin D-sub connector at the location shown in Figure 1-3.
See also Appendix A for additional information.
1.6.5 Pneumatic System
The Model 300M is equipped with a vacuum pump capable of pulling 800 cc/min across a flow
restrictor. This allows a smooth, stable flow of sample through the analyzer.
Sample enters the analyzer through a particulate filter element (47 mm diameter) mounted
immediately behind the front panel. The sample then enters directly into the sample cell. Please
see Figure 1-1 for a flow diagram and Figure 1-4 for pneumatic connections.
1-12
Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
1.6.6 Sample Gas Connection
1/4" O.D. PTFE tubing is needed to connect the sample source to the analyzer. See Figure 1-4.
NOTE
Use PTFE, glass, stainless steel or non-reactive materials for
sample gas connections.
NOTE
Use vent line when sampling from pressurized manifold - sample
pressure should not exceed ± 2 mm Hg.
1.6.7 Zero/Span Valve Connections
Zero air and span gas manifolds should supply their respective gases in excess of 800cc/min
demand of the analyzer. The manifold should be vented to the outside atmosphere and be of
sufficient length and diameter to prevent back diffusion and pressure effects. See Figure 1-4.
1.6.8 Exhaust Connections
A single 1/4" O.D. tube should be connected from the analyzer sample exhaust to an area outside
of the room the analyzer occupies. The maximum length of the exhaust line should not exceed 3
meters (See Figure 1-4).
Connect the exhaust (and vent) fitting on the rear panel to a suitable
vent outside the analyzer area and away from personnel.

The Model 300M Analyzer is now ready for operation.
1. Read Sections 1.3 and all of Section 4 of the manual to understand the analyzer operation.
2. Turn on the power by pressing the on/off switch on the front panel (see Figure 2-1). The
display should turn on and green (sample) status LED should be energized. The green LED
should blink indicating the instrument has entered the HOLD-OFF mode. Sample mode can
be entered immediately by pressing the EXIT button on the front panel. The red "fault" light
will also be on until the flows, temperatures and voltages are within operating limits. Clear
the fault messages.
3. After a 30-minute warm-up, review the TEST function values in the front panel display by
pushing the left most keyboard button labeled TEST. Not every TEST function is a
diagnostic of correct analyzer operation, therefore TEST functions not covered below can be
ignored for now.
4. CO REF, CO MEAS - TEST function values should be between 2500 mV and 4700 mV.
5. Pressure - 29 to 30 Inches-Mercury-Absolute at sea level. Other values will be displayed
depending on altitude of analyzer.
6. Sample Flow - 800 cc/min ±20 %.
7. Sample Temp - Ambient temperature (10 - 40°C) ± 10°C.
8. Optical Bench Temp - 48°C ± 1° The computer drives the temp to this setpoint.
9. Filter Wheel Temp - 68°C ± 2° The computer drives the temp to this setpoint.
10. Box Temp - Ambient +10°C.
11. DC Power Supply - 2500 mV ± 200 mV - This is a composite of all of the DC voltages in the
instrument. The value is not important but it should be within the range indicated.
12. If the TEST functions are within the limits given above, the instrument should function
correctly. If there is a problem, please read the manual and check your setup and test values.
The Model 300M is now ready for calibration (see Section 3.1).

1.8 Options
1.8.1 Rack Mount With Slides
This option, including slides and rack mounting ears, permits the analyzer to be mounted in a
standard 19" wide x 30" deep RETMA rack.
NOTE
A 1¾ minimum separation between each instrument must be
maintained to allow for air circulation. Blocking the air inlet vent on
the bottom of the analyzer will result in internal overheating.
1.8.2 Span Valve
The Span Valve option consists of stainless steel solenoid valve mounted inside the analyzer
connected to admit sample gas or customer-generated span gas.
The valve is controlled from the front panel push-buttons, the auto-timer via the RS-232
interface, or by remote contact closure.
A span gas manifold should supply at least 1000 cc/min. The manifold should be vented to the
outside atmosphere away from the personnel.
A span gas manifold can be connected to the analyzer in either of two ways.
1. If it is desired to use span gas directly from a pressurized source (e.g. a gas cylinder) the
connection can be made directly to the Pressure Span port on the analyzer rear panel. In this
case the Vent/Span port at the rear panel should be vented to a suitable exhaust manifold at
ambient atmosphere pressure. The pressure regulator on the gas source (cylinder should be
sent to provide 20 - 25 PSI delivery pressure).
2. If it is desired to use span gas from a source which delivers gas at atmosphere pressure (e.g. a
calibrator), the span gas manifold should be connected at the Vent/Span port at the analyzer's
rear panel, and the Pressure/Span port should be capped.

2 OPERATION
2.1 Key Features
The important features of the Teledyne API Model 300M CO Analyzer are listed below.
2.1.1 CO Readout
The Teledyne API Model 300M CO Analyzer constantly displays the current Carbon Monoxide
reading (in PPM) in the upper right hand corner of the alphanumeric display.
2.1.2 CO Analog Output
The Teledyne API CO Analyzer provides a buffered analog output of the current CO readings on
each of two pairs of outputs on the rear panel (see Figure 1-3) for DAS and recorder reporting.
The analog outputs provide for 20% over-range. For example, on the 500 PPM range the
M300M will correctly report concentrations up to 600 PPM and output up to 6.00 volts to the
DAS and recorder outputs. In addition TEST function values can be routed to a third analog
output.
2.1.3 E2ROM Backup Of Software Configuration
The Teledyne API CO Analyzer has a few jumpers that need to be set by the operator.
Configuration of the analyzer is done under software control and the configuration options are
stored in electrically erasable (E
analyzer is powered off.
There is one exception to this. The analog output voltage ranges are set by jumpers on the A/DI/O board as shown in Section 10.6.3.

) ROM. Thus, configuration options are saved even when the
2.1.4 Adaptive Filter
The M300M CO Analyzer is able to provide a smooth, stable output by means of an adaptive
filter. During conditions of constant or nearly constant concentration the filter is allowed to grow
to 200 samples (1 minute) in length, providing a smooth, stable reading. If a rapid change in
concentration is detected, the filter is cut to 20 samples to allow the analyzer to quickly respond
to rapidly varying signals.
2-1
Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
2.1.5 Data Acquisition (DAS)
The Model 300M contains a flexible and powerful built in data acquisition system (DAS) that
enables the analyzer to store concentration data as well as many diagnostic parameters in its
battery backed memory. For more information on programming custom Data Channels, a
supplementary document containing this information can be requested from Teledyne API.
2.1.6 RS-232 Interface
The M300M CO Analyzer features an RS-232 interface which can output the instantaneous
and/or average CO data to another computer. It can also be used as a command and status
channel to allow another computer to control the analyzer. Refer to Appendix Figure A-1 or
Appendix A for details on the RS-232 interface.
2.1.7 Password Protection
The M300M CO Analyzer provides password protection of the calibration and setup functions to
prevent incorrect adjustments to the analyzer. There are two levels of passwords which
correspond to operator, supervisor/maintenance, and analyzer configuration functions. When
prompted for a password, any of the valid passwords can be entered, but the CPU will limit
access to the functions allowed for that password level. Each level allows access to the functions
of all the levels below plus some additional functions. Table 2-1 lists the password levels and the
functions allowed for each level.

The operator and setup passwords can be disabled. To do this, enter
setup-password and toggle “ON” to “OFF”. Push “ENTR” and the
passwords will be displayed.
2.2 Front Panel
This section describes the operator interface from the point of view of the front panel. The front
panel consists of a 2-line by 40-character alphanumeric display, 8 push buttons, and 3 status
LED’s. Each of these features is described below.
2.2.1 Front Panel Display
The display is divided into 4 main "fields": the mode field in the upper left, the message field in
the top center, the sample concentration field consisting of the most recent instantaneous Carbon
Monoxide value field in the upper right, and the MENU field which occupies the entire bottom
line of the display. A typical display is shown in Figure 2-1.
2-3
Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
Figure 2-1: Model 300M Front Panel
The mode field indicates the current mode of the analyzer. Usually, it shows "SAMPLE",
indicating that the instrument is in the sample mode. Manual span checking or calibration can
only be performed by pressing the buttons on the front panel labeled "CALZ", "CALS", or
"CAL". Automatic span check only occurs at the preset time. Dynamic span adjust can be
performed during automatic or remote span checks. Remote span adjustment is performed via a
command from the RS-232 or the external contact closure inputs. Calibration and span
adjustments are discussed in greater detail in Section 3.1. Table 2-2 lists all the possible modes
in the analyzer and their meanings.
