3.5.3 Leak Measure Mode (Timed Average Leak Rate Measurement)

Note:

Compressing a gas generates heat. Gas heated or cooled in an enclosed volume

causes a pressure change. It is important, especially for leak testing, to allow enough
time for the heated gas to cool and the pressure to stabilize.

When setting the rate timer, consider three factors:

The volume of the system to be tested (large volumes take longer to stabilize).

The pressure change (the higher the change the greater heat generated).

The ambient air temperature.

Static channel altitude 5,000 ft, measure leak:

Rate timer setup:
1. Wait = 05.00 minutes
2. Test = 01.00 minutes
