c. Enter Specific Gravity in AEDATS under initialization (fuel correction factor) for PPH on
Calibration sheet.
(1) Enter the fuel flow correction factor or linearizer conversion factor into calculating counter CH 4
C switches. Enter this value in the five thumbwheel switches marked "C".
Provide corrections and place formula 78 X 8.337 X SG / 2000 in correct context.
K- Factor = Hz. x Time base / Flow rate
(Note: enter c=01000 into counter to read frequency)
PPH= GPM x 500 x SG.
or GPM= ___PPH_____
500 x S. G.
PPH= Pulses per second (hz). X 3600 x S. G. x 8.347 / pulses per gallon ( K Factor)
(2) At the Fuel Trailer, open the cover of the Flow Linearizer (P/N LN 5-C-V1B6) mounted next to the J-
box. Connect the CEC 2700 oscillator from J2 connector A(+) and B(-) to TB 201 terminals 1+ and 2-.
NOTE
Note: The T63 Fuel Flowmeter is an RF carrier type flowmeter.
(3) Set the CEC 2700 oscillator at the following points and record the indication on the calculating
counter and AEDATS:
