Note

The high alarm and STEL alarm have the same priority. A high alarm and/or STEL alarm overrides a low alarm and/or TWA alarm. To check

STEL and TWA alarms specifically, press and hold

C and D simultaneously.

The vibrator alarm is disabled at -20°C.

The high and low alarms deactivate when the gas concentration is lower than the low alarm setpoint. If the alarms are set to latch, alarms

persist until the gas concentration is below the alarm setpoint and the alarms have been acknowledged by pressing

C. The TWA and STEL

alarms deactivate by clearing the TWA and STEL peak exposure. Refer to Clearing Gas Exposures
