Your fuel level gauge can be manually calibrated to YOUR
existing fuel tank sender or calibrated by selecting one of the
preset calibration curves available. To enter fuel level calibration
follow these steps below.
1. While gauge is powered up, press and hold button down for
10-12 seconds until pointer swings
and stops at ‘1/8’ tank.
You are now in calibration mode. On some models, the button
is on the front of gauge. Other models, the button plugs into the back of gauge.
2. Release button and momentary press/release button to toggle
between available resistive ohm options. (see chart above). Pointer will travel to each available setting with quick button press. At desired
ohm range press and hold button down for 2 seconds to select that range.
3. Pointer will then travel to ‘E’ (note: on gauges with LED on front, the LED will blink 2 times to indicate the setting is saved) Gauge will exit
menu and return to normal operation.
*** Manual calibration***
If your sensor is different from the preset ranges you can manually calibrate the gauge. Follow steps above and select the ‘F’ tank tick mark to
enter manual calibration.
1. Follow steps 1 & 2 above and select (manual calibration ‘F’ tank).
2. Release button (pointer will oscillate between ‘E’ and ‘F’.
3. When pointer is at ‘F’ or ‘E’ - press and release button to calibrate that condition. For example: If the tank was drained with no gas you
would select the Empty position ‘E’ on the dial.
4. Pointer will then travel to ‘E’. (note: on gauges with LED on front, the LED will blink 2 times to indicate the setting is saved) Gauge will exit
menu and return to normal operation. Repeat procedure to set OTHER end point. Note: until both empty and full points are calibrated the
gauge will NOT read correctly. Both end points must be set before gauge will read correctly.
Note you can reset gauge calibration as many times as needed, repeat procedure above.
Note: make sure fuel level sensor is hooked up to gauge and is at the appropriate empty or full state you wish to calibrate.
Fuel level sensor MUST be attached to gauge during calibration procedure(s).
