NOTE: This test determines that the fuel quantity signal
conditioner and indicators perform accurately to a
pre
−
set capacitance (to give the simulated fuel
quantity shown above). This test does not check
the integrity of the fuel probes or ensure full and
empty calibration nor does it check that the actual
fuel level is measured correctly.
