Test functions are shown on the front panel display while the analyzer is in
SAMPLE mode. They provide information about the present operating status of
the instrument and can be used troubleshooting and can be recorded in one of the
DAS channels (Section 4.7) for data analysis. To view, press <TST or TST>.

The full scale limit at which the reporting range of the analyzer is
currently set. THIS IS NOT the Physical Range of the instrument.
See Section 4.8 for more information.

The demodulated, peak IR detector output during the measure
portion of the GFC Wheel cycle.
The demodulated, peak IR detector output during the reference
portion of the GFC wheel cycle.
The result of CO2 MEAS divided by CO2 REF. This ratio is the
primary value used to compute CO
displayed is not linearized.
The absolute pressure of the Sample gas as measured by a
pressure sensor located inside the sample chamber.
Sample mass flow rate. This is computed from the differential
between the pressures measured up-stream and down-stream of the
sample critical flow orifice pressures.
The temperature of the gas inside the sample chamber.
Optical bench temperature.
Filter wheel temperature.
The temperature inside the analyzer chassis.
O sensor cell temperature.
2
The drive voltage being supplied to the thermoelectric coolers of the
IR photo-detector by the sync/demod Board.
The sensitivity of the instrument as calculated during the last
calibration activity. The SLOPE parameter is used to set the span
calibration point of the analyzer.
The overall offset of the instrument as calculated during the last
calibration activity. The OFFSET parameter is used to set the zero
point of the analyzer response.
O slope, computed during zero/span calibration.
2
O offset, computed during zero/span calibration.

Displays the signal level of the TEST analog output channel. Only
appears when the TEST channel has been activated.
The current time. This is used to create a time stamp on DAS
readings, and by the AUTOCAL feature to trigger calibration events.
