2.3 Gas Leak Detection with audible signal
When the rotary switch (Item 1) will be turned to position 1.4 the
detector will operate with pulse signal. This alarm is triggered when
the pink scale area (Item 12) is reached and it switches-off
automatically after the gas concentration is reduced. Thus the
instrument must noch be constantly observed by the operator.
When the final red scale area is reached the constant signal will be
triggered. This continues until it is cancelled by pressing the key
(Item 2).
