    B. Display Setup – Configuring display format The Display Setup allows the user to configure the display as a 2 or 4-parameter format (refer to Figure 28 and Figure 29). While operating in Aeronautical mode for example, the 4-parameter format will allow ALT, ROC, CAS and MACH or ALT, ROC, CAS, and RtCAS to be displayed.

  • Page 45: Figure 33 Leak Rate Timer Results

    1. Leak Rate Timer – this is the traditional leak testing that allows the user to set the desired target values of ALT and CAS. Once the Test Set achieves those target values, the user selects the following Menu sequence in Leak Measure mode: 2.

    Figure 34 Select ATP Leak Test Profile The ATP Leak Test provides the following profile options (refer to Figure 35 and Figure 36): a) ALR: “Auto Leak Recover” can be “(X)” selected/deselected. b) Ambient Comp: Can be “(X)” select/deselected. Ambient Comp compensates for local ambient barometric pressure to ensure for example that a 5,000 ft.

Go To Ground can be selected while operating in Leak Measure or Control mode (refer to Figure 37).

  • Page 48: Figure 37 Go To Ground Confirm Screen

    Main Menu: Go To Ground (refer to Figure 37) Figure 37 Go to Ground Confirm Screen 1. The user can select “Go To Ground” from the Main menu, while in either Leak Measure or Control mode. At the conclusion of Go To Ground (refer to Figure 38), the Test Set will perform an AutoZero function to trim off any small Qc pressure offset that may have crept into the Qc transducer typically due to thermal component (Test Set Warming or cooling).

  • Page 49: Figure 39 Setup 1

    3. After a Go To Ground function is performed, the Test Set will remain vented to ambient until “Ok” is selected. Note: Selecting “Ok” results in the internal ambient valve closing. The unit is now a sealed system, no longer vented to ambient. Under these conditions it is normal for the displayed ALT and CAS values to be affected over time by thermal conditions changing within the Test Set.
