The test functions available to be reported are listed in Table 5-9:
DESCRIPTION
TEST CHANNEL IS TURNED OFF.
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 absolute pressure of the Sample gas as
measured by a pressure sensor located inside
the sample chamber.
Sample mass flow rate as measured by the
flow rate sensor in the sample gas stream.
The temperature of the gas inside the sample
chamber.
Optical bench temperature.
GFC Wheel temperature.
The current temperature of the O
measurement cell.
The temperature inside the analyzer chassis.
The drive voltage being supplied to the
thermoelectric coolers of the IR photo-
detector by the Sync/Demod Board.

1 When option installed.
Once a function is selected, the instrument not only begins to output a signal on the
analog output, but also adds TEST to the list of test functions viewable via the front
panel display.
