3.10 Working with the Gas Alarm (Leak Detector Option)
3.10.1 Gas-Alarm Light Plus Audio Feedback
When the LEAK DETECTOR option is selected in the AUDALRM menu, the instrument provides a ticking sound via
the internal beeper and flashes the red ALARM LED at a rate proportional to the displayed reading. At 0 ppm the
rate is approximately 1 per second. The range over which the tick sound is scaled is set using the “RANGE” menu
(taking the place of the LEAKLVL menu option).
During a purge cycle the tic sound is suspended to let the operator know that the instrument is not sampling.
Purging typically completes in approximately four seconds.
If power is removed or the product turned off, “Leak Detector Mode” remains set.
It is not possible to silence the Gas Alarm when LEAK DETECTOR operation is selected.
3.11 Clearing the PPM & Faults Data
Up to 200 gas measurements and 30 fault events are stored by the monitor.
To clear stored data, first display the data to be cleared by selecting the PPM
LOG or FAULTS function per
