Leak Detect
or Operation
Th
e monitor can be configured to operate as a Leak Detector by setting the AUDALRM function to LEAK
DETECTOR.
When configured as a Leak Detector, the monitor will produce a leak detector type of audible feedback. At zero
ppm there will be a tic every 2 seconds with the tic rate increasing up to 20 tics/second when the ppm level
reaches the ALRMLVL setting.
Standby Mode
After the monitor has been turned ON and allowed to warm up, the monitor can be placed into a Standby
Mode, ready for operation without waiting an additional 15 minutes before using. While in standby, the
monitor will stop taking gas samples and stop purging itself from the internal purge-air bag.
Place the monitor into its Standby Mode by pressing both the ENTER and ESC buttons at the same time.
Take the monitor out of standby by again pressing both the ENTER and ESC buttons.
When the monitor is taken out of standby, the operator must refill the purge-air bag by pressing the
ENTER button. Refilling the bag after coming out of standby re-establishes the monitor’s ambient pressure
reading and ensures that the purge-air bag is filled at the start of taking gas measurements.
WARNING: Fill the purge-air bag in a clean, fresh-air environment that is at the same
temperature and humidity as the area being check for gas. DO NOT fill the bag in an
area that is contaminated with sulfuryl fluoride gas.
