Calibrating the Fuel Level
To calibrate the fuel level reading with the actual amount of fuel
in the tank, you will need to start with a tank that contains the
amount of fuel you require for its reserve and progressively fill it
with known quantities of fuel. While filling the tank, you must
use at least two and possibly as many as ten (the maximum
permitted) calibration points to set values for accurate fuel level
readings. More than five calibration points are recommended,
with the first at zero (empty), the second at one gallon, the third
at two gallons and the remaining points divided equally across
the amount of fuel still required to fill the tank completely.
Use the following procedure:
Set the Display System to configuration mode.
1. Decide how many calibration points and the amount of fuel
for each that you are going to use. For example, to calibrate
the readings for a 10 gallon tank for the following
quantities, the following seven calibration points are
suggested: 0, 1gal, 2gal, 4gal, 6gal, 8gal, 10gal.
For a 20gal tank, ten calibration points are suggested: 0,
1gal, 2gal, 4gal, 6gal, 8gal, 11gal, 14gal, 17gal, 20gal.
Empty the tank so that it contains only the amount you require
as its reserve. Use the fuel pump to empty the tank. Add the
reserve fuel, for example, 0.5 gal.
You may wish to enter these values into the table on page 25. If
you ever have to return the unit for servicing, supplying the
values from this table will allow Auto Meter to automatically
recalibrate the fuel display so that you will not have to repeat
this process.
You should now drive to your local gas station. Fill the car on
level ground in order to complete the calibration process.
To make the calibration process more efficient it is
recommended that you have one person to operate the gas
pump & one person to operate the switches for the Dash.
