PRESSURE SENSOR CALIBRATION
To calibrate the pressure sensor, provide:
- A ZERO value (system with zero pressure)
- A reference value (e.g. system with 5 bar)
It is necessary to have:
- An auxiliary manometer on the same delivery circuit of the inverter
- Operate the pump (open a tap)
To access calibration, starting from INVERTER in STAND-BY
