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:
F 39.0 GAL
2 19.5 GAL
E 0.0 GAL
2. This screen shown below 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. Cycle power between readings
(hold in button 4), 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.
