3.5.2 Filling the Purge Air Bag
WARNING:
Fill the purge-air bag in a clean, fresh-air environment that is at the same temperature

contaminated with refrigerant gas.
The following message is displayed when the monitor’s purge air bag is empty and needs refilling. Press

two functions:
MEASURE
indicates that the monitor is actively measuring gas. In the screen shown above, 10 ppm of

the past. The measurement cycle runs for 4 minutes.
To reset the peak value to zero, press the
