If necessary, SELECT AERO UNITS:

2.2.1  Method

1. Connect the instrument to the static system and, if required, apply a pressure correction 

value of the pressure of the day (POD) as detailed on page

 

6.

2. Close the release valve and manual let-down valve, using the hand-pump, generate the 

required altitude.

3. Set WAIT and DURATION of the leak test times:

4. When ready, press the RUN key (F2):

Note: 

Initially, the WAIT period counts-down, followed by the TIMING period. The START 

ALT is recorded as soon as the timing period starts. At the end of the test the display shows 

the complete details of the test.

5. Record the displayed operating data.
6. To perform another leak test, use the hand-pump to generate a new system altitude and 

press RUN (F2) again.

7. On completion of the test, allow the altitude to decrease until it is below 1500

 

ft.

8. Slowly open the manual let-down valve to return the system to ground level.
9. To exit or cancel leak test mode, press TASK.
