Custom Sensor Calibration
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. Connect a momentary switch to the black and brown sensor select wires (see illustration on previous page) or alternately, touch
the stripped ends of the brown and black wires to simulate pressing the button.
3. Press and hold the button, and apply power to the gauge. The needle will begin sweeping back and forth stopping momentarily

momentarily pressing the button. Allow the needle to reach the
4. Remove power from the gauge to enter custom calibration mode.
5. Re-apply power to the gauge, the needle will move to a position just below the empty mark, indicating that the empty calibration
point can be entered.
6. With an empty, or nearly empty tank, capture the empty calibration point by momentarily (less than one second) pushing the
switch. After approximately 1 second, the needle will move to just above the full mark.
7. Fill the tank and momentarily press (less than one second) the sensor select button or touch the brown and black wires to
capture the full calibration point. After approximately one second, the gauge will reset, and begin reading fuel level per the
custom calibration.
8. Confirm that the gauge reads the proper fuel level.
9. If the proper fuel level is read, go to step 10. If proper fuel level is not read, return to step 3 and recalibrate.
10. Remove switch if used, and tape the ends of the brown and black wires, so they can not touch.
Sensor Error
If no sensor is connected, the needle will move to the empty position indicating an error. Approximately 4 seconds after the sensor
is connected, the needle will move to the indicated fuel level and will resume normal operation.
Power-Up
The needle will move backward to the stop pin and then display actual fuel level. This procedure is an auto-calibration function and
is performed on every power-up. While this test is being performed, the gauge may make a clicking sound. This is normal.
