Make sure that other ports in the system being tested are sealed before continuing. 3. It is recommended to have the 1811NG chassis grounded to the aircraft or UUT using the Ground stud located in the upper-right corner of the panel as depicted in item 5 of Figure 4. -
Page 59: Figure 57 Unit Safe At Ground
Note: The 1811NG is capable of conducting a combined Pitot and Static test (as described above) or individual system leak tests. To accomplish a single channel (Pitot only or Static only) modify the procedures by simply not entering Target value for the parameter / channel. - Page 60 1. For detail explanation of the ATP Leak Test capability and parameter field descriptions, reference section B-3.30 “Using Method-(2) ATP Leak Test”. 2.

- Page 67 PITOT (Pt) channel. Similarly, if the user enters a MACH Target value then MACH is the controlling parameter. With a Target value entered for MACH “i.e. Constant MACH”, once the 1811NG reaches the Target MACH value, the PITOT (Pt) channel controller will continue to maintain the MACH value requested while the STATIC (Ps) Target value is changed by the user entering a different ALT Target.

2. Method 2: EPR Testing using EPR Mode. The 1811NG has an actual EPR Mode that can be used to test the EPR transmitter. EPR = Pt/ Ps (where Ps= Inlet pressure and Pt=Outlet pressure). In EPR Mode the 1811NG provides display of the individual pressures for PT2 and PT7 as well as the exact EPR Ratio resulting from the equation of PT7 / PT2. -
Page 70: Shutdown Procedure
Enter the first Pt (PT7) pressure Target value or the first EPR Target. e) After the 1811NG achieves both the Target values confirm the EPR Ratio reading. f) Repeat the process by entering both Target values for all increments of test. - Page 71 CAUTION: Do not remove STATIC (Ps) or PITOT (Pt) hose or Nav-Aids adapters before Test Set displays “Unit Safe at Ground”. 3. Switch Power OFF. 4. Disconnect the STATIC and PITOT hoses from the aircraft ports and or adapters. 5.
