11.9.1
Home > Data and settings > Implement settings > Device calibration > Press. sensor zero value
In case a pressure value other than zero is displayed despite the absence of pressure inside the circuit , it is necessary to perform zero calibration
of the sensor.
Before carrying out any operation disable the pump by disconnecting it from the power supply.
Make sure that the pump is correctly disabled, then open the main valve and all section valves.

Unstable signal!
If this alarm is displayed, anomalous pressure values have been detected:
check the conditions described at the beginning of the paragraph (absence of
residual pressure, pump disabled). If the problem persists, check the correct
sensor connection and operation.
11.9.2
Home > data and settings > implement settings > Device calibration > Tank level zero value
ALWAYS PERFORM THIS OPERATION WHEN A LEVEL SENSOR OF THE SYSTEM IS REPLACED.
If the VT detects the presence of fluid inside tank, even if empty, set the level sensor to zero;
To use this menu the level sensor must be active (basic settings, chap. 10).
