The fuel level gauge can be custom calibrated to accurately display the output
from any fuel level Sensor with an output between 0 and 270 ohms.
1. Make sure the fuel level Sensor is connected to the gauge and that the
fuel tank is empty, or nearly empty, before proceeding.
2. Press and hold the “A” button and apply power to the gauge. Keep holding
the “A” button until the dial illuminates blue (about 15 seconds).
3. Release the “A” button, the dial will move to the 1/8 tank mark indicating
the current selected Sensor (see chart below).
4. Press and hold the “B” button until the pointer sweeps to the 7/8 tank
mark. This will select the custom Sensor.
5. Remove power from the gauge to enter custom calibration mode.
6. Re-apply power to the gauge, the pointer will move to a position just below
the empty mark, indicating that the empty calibration point can be entered.
7. With an empty or nearly empty tank, capture the empty calibration point
by momentarily (less than one second) pushing the “A” button. After
approximately 1 second, the pointer will move to just above the full mark.
8. Fill the tank and momentarily (less than one second) press “B” button
to capture the full calibration point. After approximately one second, the
gauge will reset, and begin reading fuel level per the custom calibration.
9. Confirm that the gauge reads the proper fuel level.
