Every time you fine tune the K factor, change it by only half of the
amount calculated above, and record the measurements here:

IMPORTANT: after adjusting K factors you must apply a correction
factor to the EDM indicated fuel USED and indicated fuel REMaining,
accordingly. We recommend you top the tanks and ‘Refuel’ the EDM to
eliminate this requirement.
Entering the K factor
1. Enter the pilot program mode by simultaneously holding the STEP
and LF buttons for five seconds until you see PROGRAM MODE.
2. Tap the NEXT button repeatedly until you see the K factor you wish
to adjust: example: ‘ LFT K-Factor 1 = 29.90’, for left engine.
3. Hold both NEXT and Button 2 until you see ADJUST . The first digit blinks
(shown here as a larger digit for illustration purposes): 2 9.90
4. Tap the DIGIT button to make digit you wish to edit blink: 2
9 .90
5. Tap the PLUS or MINUS button to change blinking digit: 1 8 .90
6. Repeat items 8 and 9 for the remaining digits.
7. Tap
SAVE to save and exit the K factor adjustment.
8. Tap NEXT repeatedly until you see END? YES , then Tap EXIT to exit the
program mode.
Note: for any ‘return flow’ transducers, we recommend you do not
attempt to ‘fine-tune’ them, however their K factors do need to be
initially entered into the EDM.
