Note: Test Set should be “Vented” to ambient and in Leak Measure mode at this
time.
From the Main Menu screen select the blue button “page2”.
Select the “Additional Functions” button. A screen is displayed with three options.
Touch “Control Mode”. Control Mode screen opens with two selections.
Select “Control Mode (Pt Only)”.
Touch “Exit” twice. Select “page 1”.
Note: The UI display is now positioned back to the Main Menu.
4. If not already done, perform a Leak Test on the Test Set and hoses.
Note: CAP the aircraft end of each hose.
5. Connect the hoses to the aircraft Pitot ports.
Note: While testing the Pitot (Pt) system with Test Set configured as “1-Channel Pt
only” mode, the Static (Ps) channel of the Test Set will remain vented to
ambient, this is the same point of reference the aircraft’s Static port is
referencing while driving the Pitot system with the Test Set.
If the Test Set is configured in its default “2-Channel Ps & Pt” mode, the
Target value for ALT should always remain at ambient Ground pressure
altitude (value determined from the last Go To Ground). While testing various
CAS values, the Tester will maintain ambient pressure altitude equivalent on
the Static (Ps) port.
It is very important that the Test Set maintains ALT = ambient pressure
altitude especially if the Static (Ps) hose is not connected to the aircraft’s
Static system.
6. Verify if the alternate pneumatic system(s) (co-pilot, standby auxiliary, etc.) shares
the same pneumatic lines. If so they must be sealed or isolated from the current
pneumatic system about to be tested.
7. If necessary, change the displayed parameters on the Test Set to those required.
From the main menu, select “Display Setup”.
On the “Display Setup” screen, select the desired aeronautical parameters.
8. If necessary, different units can be selected by touching “Units” from the Main Menu.
9. Verify the limits selected are appropriate for the aircraft and or Instruments that are
going to be tested.
10. At this time confirm the following has been accomplished:
