3.5 Peak Reading Operation

In addition to displaying the current SF

level, the monitor can also be set up to display its peak ppm

measurement.

The peak reading display is selected by using the 2ndUNIT function (page 17).

The display above shows that currently the monitor is detecting 100 ppm SF

and that a peak

measurement of 500 ppm has occurred.

The peak reading is reset by pressing the ENTER button.

3.6 Leak Detector Operation

The monitor can be configured to operate as a Leak Detector by setting the AUDALRM function (page 16)

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 per second when the

ppm level reaches the ALRMLVL (page 16) setting.

3.7 Standby Mode

After becoming operational, the monitor can be placed into a Standby Mode. When taken out of standby

the monitor is ready for operation without waiting an additional 5 minutes to warm up. While in standby

the monitor will stop taking gas samples and stops purging itself from the 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 checked for gas. DO NOT fill the

bag in an area that is contaminated with SF

gas.

As soon as the purge-air bag has been refilled with fresh air, the Data Display screen appears and the

monitor resumes normal operation.
