• Be sure to use the verification function when the sensor is in the full pipe state. If the sensor is
in the empty pipe state, the function to detect adhesion may not run normally.
• When using the verification function, correctly specify the fluid status with the parameter.
• If there is a problem with the result of the verification function, refer to the Maintenance
Manual.
5.9.7 Electrode Insulation Deterioration Diagnosis (only
