When you calibrate the sensor, the current CNT value is saved as either the Full calibration

value (if you press the

Full

button) or as the Empty calibration value (if you press the

Empty

button).

How to and why calibrate sensors?

Initially, the sensor is calibrated at its original length.

Once you change it by cutting or

extending the tubes, you need to recalibrate it

i.e. to record the new CNT values that the sensor

calculates when its tubes are either full or empty.
