Calibration Procedure: this is the core of the system; significant precision is required in
entering calibration data to guarantee accurate sensor measurements.
The procedure allows up to 50 points to be entered: the

buttons are used to select the points, before
confirming the point by pressing OK. This brings you to the Volume selection: use the

buttons to
enter the number of Litres/ImpGal/USGal corresponding to the calibration point, as read by a flowmeter,
then confirm the figure with the OK button. To return to the calibration point selection without confirming
its value, press the
←
button.
NOTE: all values between one point and the next are calculated by interpolation, litre per
litre (or gallon per gallon). Depending on the shape of the container (tank), which may be
more or less complex, and the need for accuracy of the measurement, more or fewer
points may be set.
For example, with just two points set, point 1 (always corresponding to 0 litres) and point 2
corresponding to 500 litres, a cubic or parallelepiped-shaped tank is assumed, without
complex shapes. On the other hand, the complexity of tanks for sprayers and the need to
know the tank level accurately makes it necessary, or in any case advisable, to set
multiple points in order to obtain precise final calibration.
The last calibration point corresponds to the maximum capacity of the container / tank.
NOTE: when the level indicator is not calibrated, the display shows the CALIBRATION
icon and the RED LED is lit on the sensor
