(9) Push and hold the PRESS TO READ CAP (pF) pushbutton.
(10)
Verify the tanks’ value is within tolerances as specified in Table 2 (Empty) and Table
3 (Full).
Note:
Verify that capacitance is within specifications. If a test in not within
specification, isolate the fault by referencing the aircraft wiring schematics and
disconnecting the probes and / or the aircraft wiring at connecting junctions.
(11) Set the T/S ON / OFF switch to OFF.
Note:
If testing the opposite side, repeat procedure.
E. Disconnecting/Reconfiguring
(1) Open circuit breakers and turn battery switch OFF (if applicable).
CAUTION:
WHEN LOWERING OR RAISING THE FUEL PANEL, ENSURE
AIRCRAFT BATTERY IS DISCONNECTED.
(2) Disconnect T/S from the aircraft wiring.
(3) Reconnect aircraft wiring plug to Indicator.
(4) Return the aircraft to its original configuration.
3. INDICATOR TEST
Note:
Refer to Precautions and Preliminary in General Information section.
Note:
Failure to calibrate the system after performing the indicator test will result in an
inaccurate fuel quantity readings.
Note:
The Indicator Bench Test (see Chapter 2, Section 2. INDICATOR BENCH TEST)
may be performed in place of the Indicator Test.
A. Aircraft Preparation
(1) Disconnect aircraft battery.
CAUTION:
WHEN RAISING OR LOWERING THE PILOT FUEL PANEL, ENSURE
AIRCRAFT BATTERY IS DISCONNECTED.
(2) Gain access to applicable Indicator.
(3) Ensure applicable fuel quantity circuit breakers are open.
(4) Break connection between Indicator and aircraft wiring plug.
B. Test Set Preparation
(1) Set T/S ON / OFF switch to OFF.
(2) Rotate the TEST FUNCTION switch to CAP SIM CAL (NORM SYS).
(3) Set the INSULATION / SYSTEM switch to SYSTEM.
(4) Set the MAIN / TOT-AUX / NAC switch to MAIN / TOT.
(5) Set the 200 (pF) / 1000 (pF) switch to 200 (pF).
