User Manual

To change the factory-set alarm setpoints, refer to the

Calibration and Setting Alarm Setpoints section.

Note

You can disable an alarm by setting the alarm

setpoint to 0 (display: - -).

Stopping a Gas Alarm

The low, high, and STEL alarm stops when the ambient gas

level returns to the acceptable range.

The detector computes the TWA value based on an 8-hour

workday. Only deactivating the detector can stop the TWA

alarm.

Acknowledge Latched Alarm

If the latched alarm option is activated, the audible and visual

alarms continue to sound and flash until the low, high, or

STEL alarm condition is acknowledged. Press C to

deactivate the audible and visual alarms when the current

ambient gas reading falls below the low alarm level. The

alarms cannot be deactivated if an alarm condition is still

present. A TWA alarm condition will not reset.

Note

A STEL alarm may take up to 15 minutes of clean

air readings before the latched alarm can be

deactivated.

Sensor Alarm

The detector tests for a missing or defective sensor during

the activation self-test. Refer to the

Troubleshooting section.

Pump Alarms

The internal pump draws air over the sensors. If the pump

stops working or the pump filter becomes clogged, the

detector activates the pump alarm.

Pump Alarm

Deactivate the detector immediately

and clear the pump inlet, hose, and

filter.

Blocked Pump Alarm

If the pump alarm continues and the

LCD advises the inlet is blocked, see

the

Pump Calibration section.
