MAINTENANCE MANUAL
(h) Reset the left indicator calibration switch (on the left side of the fuel quantity module) from
“CAL” to “RUN” (i.e. - move it towards the rear of the module). This will return the module
to normal operating mode.
(i) Initiate calibration for the right fuel quantity module analog indicator per (1) above and
then steps (2) (a) thru (h). The right indicator calibration switch is on the right side of the
fuel quantity module.
(j) Reinstall the fuel quantity module in the instrument panel.
D. Complete procedure as follows:
(1) If used, disconnect the digital ohmmeter.
(2) Disconnect the external power supply unit.
(3) Replace access covers.
4. Fuel Gauge Full Range Check ( S/N’s 4636021 thru 4636374. )
(PIR-PPS60032-13, Rev. O.)
NOTE: Full Range Check for S/N’s 4636001 thru 4636020 only , is provided under Fuel Quantity Gauge
Accuracy Test, above.
A. Set up per Fuel Quantity Gauge Calibration, Set up, above.
B. Non-Programmable Transicoil EMIS Gauge ( S/N’s 4636021 thru 4636131 only ).
NOTE: The Programmable Transicoil EMIS Gauge (P/N 602-222) installed in S/N’s 4636132 thru
4636374 as original equipment is backwardly compatible and may be found installed in
S/N’s 4636021 thru 4636131 as a service spare. These modules can be identified by the
absence of potentiometers and the presence of a calibration switch on the left side of the
module. If found, full range check per Programmable Transicoil EMIS Gauge, below.
(1) Defuel both fuel tanks. As fuel level decreases to 5 +0/-1 gals, verify the low fuel alarms sound.
(2) When defueling is complete, verify that the needles on analog gauges are pointing to the areas
of the "E" graduations as described in Fuel Quantity Gauge Calibration, Non-Programmable
Transicoil EMIS Gauge, above. If pointers are out of prescribed range, vibrate the tanks by
bumping their lower surfaces. Repeat Fuel Quantity Gauge Calibration, Non-Programmable
Transicoil EMIS Gauge, above, if the pointers do not return to the prescribed range.
