1.
Manual mode of calibration , actions:
- Choose the "MANUAL" sensor calibration mode
- Select the data source connected to the sensor. INPUT1 ... INPUT4 - for analog or frequency sensors,
DUT1 or DUT2 – for digital sensors connected to the ports PORT1 or PORT2 respectively
- Choose the sensor type: analog, frequency or digital
- Specify the initial fuel level if the tank has been already filled with fuel or calibration process has been
interrupted and it shall be resumed.
- Specify the volume of fuel that shall be poured for 1 time (portion). Another value in the calibration
process will indicate how many liters have already been in the tank. If another portion has less or more fuel than
specified, the value can be corrected before entering into to the calibration table
- Press the "START" button and fill the tanl with the first portion equal to the portion value specified in
the preceding paragraph.
- Press the "RECORD" button. In the table of values the sensor readings corresponding to the amount
of fuel poured in the tank will appear.
- Continue to pour fuel intill the tank is completely filled by pressing the "Save" button after each
portions.
- When filling the tank, press the "STOP" and save the table into a file, or one of the two calibration
tables in the memory of the device.
- Press the "Clear" button before starting the next calibration of fuel gauge.
2. Automatic calibration mode.
The calibration is carried out fully automatically without a user. In this
mode, a pump, which is controlled by the NAVISET device based on the data from the flow meter and the
pauses between meals, is used for fuel filling. Before starting the calibration process, it is necessary to make or
buy a ready-made stand. To make a stand the following components are required: sparkless pumps for liquids, a
pump control relay (selected on the basis of the capacity of the pump), fuel flow meter, a button with fixation
with normally-closed contacts (for emergency shutdown of the pump in the event of a failure in the process of
calibration) and a resistor of 1 kOhm.
