6.9 Diagnostics Screen
The DIAGNOSTICS menu provides information regarding the operation of
the analyzer. Information includes the following:
Time Meters - Displays the run time of the analyzer and sample pump in
hours of operation.
Main Diagnostics - Lists the current status of the Stack and Air Thermo-
couple channels, Reference Temperature channel, Pressure channel, CO
channel, O
