• When removing and inserting the sensor from or into the in-line
• The sensor must be kept damp after commissioning, e.g. the in-line
Assemble the sensor as described in the operating instructions manual for
the in-line probe housing.

Do not switch the measuring system off when using intermittently.
If necessary, use a timer to switch on metering equipment.
