than when it was tested at the factory. To insure accuracy, which is essential, the FP-5(L) provides a pilot-
programmable K Factor to correct for these differences. Initially, the FP-5(L)'s K Factor is set to a value which is
marked on a tag supplied with the flow transducer. At each fill up the K factor may be changed using the "Auto
Calibrate Mode" or the K Factor may be manually changed in the Power-up Programming.
5. “USED” Display Mode:
In the “USED” Display Mode, the FP-5(L) will display the "Fuel Used Since Fill Up." By tapping either
"PRG" button the display will toggle between "Fuel Used Since Fill Up" and "Fuel Used for the Flight" (dis-
played with a "F" in the front of the value). The Fuel Used for the Flight is measured from the time the aircraft's
electrical power was turned on. If the electrical power is turned off, the Fuel Used for the Flight will reset to
"000." The "Fuel Used Since Fill Up" is held in permanent memory and reset to "000" when you enter the "Add
Fuel" or "Auto Calibrate" modes.
