At the conclusion of the ATP Leak Test, the DPS1000 will automatically
perform a Go To Ground function and the following screen will display the
results.
Figure 54 ATP Leak Test Results
This concludes the ATP Leak Test.
C. APPLYING LEAK CORRECTION
If the leak rate does not exceed 2 kts/min or 50 ft/min, record the leak rate of the Test Set
and hoses so that the values can be subtracted from the aircraft’s leak test. The calculated
value removes the leaks caused by the Test Set and hoses, and isolates the aircraft
systems’ leak rate.
11. AIRCRAFT TESTING
CAUTION: Observe all safety precautions detailed in the “AMM” Aircraft Maintenance Manual.
CAUTION: When using STATIC (Ps) only, make sure that the differential pressure “Qc” stays
within the limits of the ASI “Airspeed Indicator”.
A. PRELIMINARY SETUP
1. Ensure the STATIC and PITOT Test Set Leak Test – (Test Set and hoses only) has
been completed and that the DPS1000 is “Safe at Ground” and Vented before
connecting the tester to the aircraft systems.
