Leak Test
The Leak Test feature allows the user to determine the leak rate in the pneumatic
system being monitored. Once configured, Leak Test monitors the measured
pressure, altitude or air speed over time and displays the leak rate in units per
minute at the conclusion of the test. The maximum configurable leak test period is
1440 min (1 day). Pressing any key during the leak test aborts the test.
