9. Add the first point, which represents empty tank situation.
Press the
OK
and select
Add
. Change volume to 0 and press
close
button. This will add the first point. Sensor value is
recorded automatically. Write this point down (volume and
sensor pair) to the notebook.
10. Pour some known quantity of fuel into the tank. Say 10 liters.
Observe the
Sensor
value at the bottom of the window. This
value must be alive – it must change. This value shows the
raw sensor reading in Ohms for the resistance based sensors
or voltage for active fuel level sensors (capacitive, or pressure
based). Note: Usually, you have to put some amount of fuel
before the fuel reaches the bottom of the sensor and the sensor
starts reacting. This amount varies from case to case and it
may be as small as 0 or as large as 15 liters (or even more). If
sensor has reacted (its value is different from the empty case)
and later on the value has stopped changing, write down the
total amount of fuel and sensor value to the notebook and then
press
OK
and
Add
. Adjust the volume to the amount of the
fuel now in tank (10 l in our case) and close it with the
close
button.
11. Pour some more fuel into the tank. Say another 10 liters. Once
the sensor stopped moving, write down the total amount of fuel
(now 20 l) and sensor value into the notebook. Press
OK
and
select
Add
. Adjust the volume to the amount of the fuel now in
tank (20 l in our case) and close it with the
close
button. The
volume numbers must always increase, while the sensor number
may either always increase or always decrease. This depends
on the sensor type.
12. Repeat this procedure until the tank is full. Be careful here.
You may have a case where sensor stops reacting (has reached
