Capturing the sender reading at each calibration point:
Getting Started…Collecting Fuel Level Calibration Data using the
EDM as a meter.
1. With power off, hold in Button 4 (Button 1 being far left) and
then turn on power. For each EDM monitored tank, create a
paper table with the desired number of calibration points (2 to 5)
and at what volume each will be. Number of calibration points to
be entered into the system later. The zero gallon point reading
is always taken with unusable fuel in the tank
. Example of a
completed 3 point table for LEFT tank:
LEFT
F 39.0 GAL 1907
2 19.5 GAL 1154
E 0.0 GAL 685
2. This screen provides real-time readings of all active fuel level
sensors. Verify readings look normal. Reading are arbitrary
whole numbers
3. Now add fuel as needed to match the required volume for a
particular point. Allow this to settle, then take a reading and
record it on paper adjacent to that point.
4. Repeat this process until all points, 2 to 5, have been recorded
for each tank.
