1. Before proceeding with the instrument setup you will require the following
information, for each tank pair or set, as it pertains to the aircraft that the
instrument is being installed on:
a. Maximum red line fuel quantity
b. Maximum yellow line fuel quantity
2. This information must be obtained from a current, traceable source for the aircraft
that the instrument is being installed on. Some possible sources are:
a. Pilot Operating Handbook
b. Maintenance Manual
c. Aircraft Type Certificate Data Sheet
d. Engine Type Certificate Data Sheet
e. Manufacturer
3. This instrument requires calibration before it will function. To calibrate each tank
you will be required to add fuel at TWO gallon increments, starting with the
unusable fuel in the tank (the legal, zero fuel point).
a. Place the aircraft in a level flight attitude and support the aircraft wings, if
necessary.
b. Drain all tanks to be calibrated.
c. Disable any cross feed between tanks.
d. Place the unusable fuel in each tank to be calibrated.
e. Complete the calibration process by following the interactive, instructions
provided throughout the process on the instrument display (See 4).
f. Calibration time is approximately one minute per two gallons of fuel.
g. Note the calibration values on the provided calibration sheets. This value
serves two purposes.
i. It demonstrates a compliant installation, and
ii. Provides a hard copy backup of all calibration data.
h. It is not necessary to complete the full calibration at once. Calibration can
be resumed at any point of the process by re-entering the setup.
