Calibrating the Fuel Level
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 are
recommended, with the first at zero (empty) , the second at five litres,
the third at ten litres, 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
50 litre (10 gallon) tank for the following quantities, the following
seven calibration points are suggested: 0, 5L (1gal), 10L (2gal), 20L
(4gal), 30L (6gal), 40L (8gal), 50L (10gal).
For a 100L (20gal) tank, ten calibration points are suggested: 0, 5L
(1gal), 10L (2gal), 20L (4gal), 30L (6gal), 40L (8gal), 55L (11gal), 70L
(14gal), 85L (17gal), 100L (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, two litres (0.5 gal.).
You may wish to enter these values into the table on p30. If you ever
have to return the unit for servicing, supplying the values from this
table will allow Stack to automatically recalibrate the fuel display so
that you will not have to repeat this process.
You should now drive to your local petrol (gas) station a 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 petrol (gas) pump & one person to
operated the switches for the Dash.
