This menu option allows you to define whether alarms should trigger
based on a high alarm or a low alarm condition.

oxygen levels (% O

). If Alarm 3 is set to trigger at the start of a cali-
bration or verification, this option does not apply.

alarm that triggers during a hydrocarbon upset condition. In this case,
you will not be able to select Alarm 4 as a low oxygen alarm. Alarm 3,
however, can still be selected as a high or low oxygen alarm.
