sensor is taken out of the measuring position. This avoids unwanted

If you would like to disconnect the sensor from the sensor connection
cable, please note the following points:

Before disconnecting the sensor from the SACIQ sensor connection
cable, the sensor has to be cleaned on the outside (see section
5.4.1).

Unscrew the sensor from the SACIQ sensor connection cable.

Place a protective cap on the sensor plug head connector and on
the SACIQ sensor connection cable each time so that no moisture
or dirt can get on the contacting surfaces.

In corrosive environments, close the socket of the sensor connec-
tion cable with the screwable SACIQ-Plug when it is dry in order to
protect the electrical contacts from corrosion. The protective plug is
available as an accessory (see section 5.5 R
EPLACEMENT PARTS AND
ACCESSORIES
).
WARNING
Chemical or biological hazard.
Contact with the sample can be harmful to the user.
Depending on the type of sample, suitable protective
measures must be taken (protective clothing, gog-
gles, etc.).
We do not recommend unscrewing the sensor from the
sensor connection cable in order to do maintenance work.
Otherwise, moisture and/or dirt can get into the plug con-
nection where it can cause contact problems.
