7.8 Pressure Sensor Zero Trim
The pressure sensor is zeroed from the factory. If it does require a re-zero,
follow these keystrokes:
When zeroing the pressure sensor, make sure there is no pressure on the system.
Ensure the pump is not running and the system is vented to atmosphere.
First, press the RESET PRESSURE SENSOR OFFSET Button. This will set
the offset to zero.
Once the pressure stabilizes, press the ‘Pressure Sensor Zero’ button to set the
system pressure at zero.
