Calibration

NOTE: If using the stock standard case, it will need to be opened using the two screws so that it can be programed. The Mad Folk case will not need to be opened as the buttons can be accessed through the holes in the case

The calibration process of this device works by programming or mapping 3 positions of the fuel sender to the guage. Full, Half and Empty. For each of the three positions, the trimming pot is adjusted so that the actaul fuel gauge reads as per the position of the sender.

To enter calibration mode:
ensure the device is powered off for at east 5 seconds
Press and hold the "F" button while turning on the ignition
Once powered on, release the "F" button
The red light should come on and stay solid. This indicates calibration mode.

Move the fuel sender float to the FULL position.
using a small screwdriver, turn the trimming pot untill the fuel gauge reads correctly (full)
then press the "F" button to store this state.

Move the fuel sender float to the HALF WAY position.
using a small screwdriver, turn the trimming pot untill the fuel gauge reads correctly (Half)
then press the "M" button to store this state.

Move the fuel sender float to the EMPTY position.
using a small screwdriver, turn the trimming pot untill the fuel gauge reads correctly (Empty)
then press the "E" button to store this state.
