CALIBRATION
Pressure sensor:
To calibrate the pressure sensor the ADC values for no pressure and for maximum
pressure must be found.
No Pressure:
The minimum ADC value is measured when there is no
pressure in the system.
Pressure max:
The maximum working pressure, in bar, of the pressure
sensor calculated from the ADC value for a reference
pressure.
Cal pressure:
A reference pressure used to calculate the maximum working
pressure of the pressure sensor.
An automatic pressure sensor calibration procedure is available for calibrating the
pressure sensor and the procedure is as follows:
