38. Adjusting the K Factor
This procedure is different than for setting other parameters.
1. If you haven’t already done so, start the Pilot Program Mode by clearing all alarms by tapping step repeatedly,
then simultaneously hold the STEP and LF buttons (for about five seconds), until you see the word PROGRAM,
followed by ‘FUEL ? N’.
2. Tap STEP repeatedly until you see K-FACTOR=29.90 (this value may be different on your unit).
3. Hold both the STEP and LF buttons simultaneously until a digit begins flashing. This indicates editing has been
enabled.
4. Tap or hold the LF button to change the flashing digit to the desired value.
5. Tap or hold the STEP button to select the next digit to edit.
6. Repeat steps 4 and 5 until the displayed value is set to your desired value.
7. To save new value, hold STEP and LF buttons simultaneously (for about five seconds) until the K factor parameter
exits.
8. Tap STEP repeatedly until you see END ? Y, then Tap STEP once more to exit the Pilot Program Mode.
39. Programming Accumulate Trip Total
Accumulate—default is OFF: resets the fuel used to 0 every time you inform the EDM-900 that the aircraft was
refueled. With accumulate ON fuel used will not be reset to 0 when you inform the EDM-900 that the aircraft was
refueled.
Select “No” if you wish to display total fuel used since the last time you informed the EDM-900 that the aircraft was
refueled. Select “Yes” to display total fuel used for an extended trip with multiple fuel stops. This selection affects only
the
USD measurement.
During normal operation, to reset the accumulated fuel used display at any time, tap STEP until you see USD. Hold
both STEP and LF until the display shows .0 USD.
