* Clearing the instantaneous GAS, STEL and TWA alarms:
by pressing momentarily on the following button
Clearing
1
the alarm involves cancelling the “ pulsed ” audible signal and turning off
the alarm indicator on condition that the user has left the danger area.
2
NB : if the audible alarm is cleared while a threshold is still exceeded : the indicator
will continue to flash and the corresponding pictogram will remain "steady".
Otherwise, the indicator will switch off when measurement is under the alarm
threshold.
* Clearing the FAULT alarms:
In the event of a fault it is not possible to clear the “ continuous ” audible and visual
alarms, except in case of over range which can be cleared.
1
An option allows to automatically regenerate the buzzer 5 minutes after the acknowledgement if the alarm is still on.
2
An option makes possible the automatic acknowledgement of alarms : the alarms automatically acknowledge as soon
as the value gets under the threshold. If this option is requested, the manual acknowledgement is no longer possible
(also the « OVER RANGE ») (untested by DMT).
