CO Measure
CO MEAS
MV
The demodulated, peak IR detector output during the measure
portion of the GFC Wheel cycle.
CO Reference
CO REF
MV
The demodulated, peak IR detector output during the reference
portion of the GFC Wheel cycle.
Measurement /
Reference Ratio
MR Ratio
-
The result of CO MEAS divided by CO REF. This ratio is the
primary value used to compute CO concentration. The value
displayed is not linearized.
Sample Pressure
PRES
In-Hg-A
The absolute pressure of the Sample gas as measured by a
pressure sensor located inside the sample chamber.

4.1.2. WARNING MESSAGES
The most common instrument failures will be reported as a warning on the analyzer’s
front panel and through the COMM ports. Section 12.1.1 explains how to use these
messages to troubleshoot problems. Section 4.1.2 shows how to view and clear warning
messages.
