Pressure sensors and messages
The following table shows the relationship of the fluid level
measurement result and the internal error message, Ex or Hx.
Note
During pressure measurement, the valves are immediately in the mode
before the pressure measurement and the pump is off.
An overview of the relationship of pressure sensors and messages is
given below.
