3.5 Display Screens
3.5.1 Initial Power Up
When the monitor is first powered up, all front panel lights turn ON and a splash screen appears showing
the monitor’s current firmware revision level. After a brief moment the Warm Up screen is displayed
along with the front panel ON light (green) blinking.
The monitor requires 900 seconds (15 minutes) to warm up; after which, the ON light glows steady and
the Data Display screen is displayed.
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
and humidity as the area being checked for gas. DO NOT fill the bag in an area that is
contaminated with refrigerant gas.
The following message is displayed when the monitor’s purge air bag is empty and needs refilling. Press
the ENTER button to start the refill process. After the air bag has been filled, the monitor will
automatically resume normal operation.
3.5.3 Data Display Screen
During normal operation, the Data Display screen shows when the monitor is performing the following
two functions:
MEASURE indicates that the monitor is actively measuring gas. In the screen shown above, 10 ppm of
R-134A gas is currently being detected, and that a peak measurement of 20 ppm has occurred sometime in
the past. The measurement cycle runs for 4 minutes.
To reset the peak value to zero, press the ENTER button.
PURGE is displayed when the monitor is resetting its infrared detector to a baseline of 0 ppm using the
air stored in the internal purge-air bag. The purge cycle runs for 10 seconds. The monitor will operate for
approximately 40 minutes before the purge-air bag needs refilling.
3.5.4 Function Screens
The Functionscreens are used to display stored data and to set up the monitor.
