Automatic Calibration – the voltage parameters of the fuel readings can be

calculated automatically by the system. In order to do so, the vehicle must
fuel the tank to 100% and then use the vehicle for a period of 2 additional
refuels of 100%. Note that the lower the level of the fuel will be prior to the
refuel, the more accurate the reading and calibration will be.
In order to do the automatic calibration, after the 2nd refuel, on Starcom
Online, go to Unit Information and open the Captions section. Select the
correct analog input in the Fuel dropdown list and click on Automatic
calibration button. When finished, press Apply.
