The CO Concentration screen, shown below, displays the current CO concentration and
the factory-set max alarm limit. The max alarm limit can be changed when the
instrument is in the service mode. Acceptable alarm limits range from 0 to 10,000 ppm.
If the CO concentration in single mode or low CO concentration in dual or auto range
mode exceeds the max alarm limit, an alarm is activated. The word “Alarm” appears in
the Run screen and in the Main Menu.
