3.5.3 Clearing the Gas Alarm
By pressing momentarily the ALARM button
Clearing the alarm involves canceling the “pulsed” audio signal and turning off the alarm indicator.
W ARNING : If the alarm is cleared while a threshold is still exceeded the operator of the instrument must leave the
dangerous area.
If the audio alarm is cleared while a threshold is still exceeded: the visual alarm will continue to flash and the
corresponding pictogram will remain "steady".
The instrument will return to normal state when measurement is under the alarm threshold.
3.5.3 Clearing the Fault Alarm
In case of a fault, it is not possible to clear the “continuous” audio and visual alarms.
