5.1 General maintenance instructions
Warning
Contact with the sample can lead to danger to the user!
Depending on the type of sample, suitable protective measures
must be taken (protective clothing, protective goggles, etc.).
Maintenance condition We recommend to switch on the maintenance condition each time
before removing the sensor from its measuring position. This avoids
unintended reactions of linked outputs. For more detailed information
on the maintenance condition please refer to the respective
IQ S
ENSOR N ET system operating manual.
Maintenance-free
operation
The TetraCon
®
700 IQ (SW) conductivity sensor operates without the
need for any maintenance.
5.2 Cleaning
If the sensor is heavily contaminated, this can affect the measuring
accuracy. Therefore, we recommend to clean the sensor regularly
according to visual checks. Thorough cleaning of the sensor is
particularly recommended before measuring lower values of
conductivity, as well as before adjusting the measured value.
Note
We do not recommend to unscrew the sensor from the sensor
connection cable in order to clean it. Otherwise, moisture and/or dirt
can get into the plug connection where they can cause contact
problems.
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 (SW) sensor
connection cable, remove any larger pieces of contamination from
the sensor, particularly in the area of the plug connection (brush it
off in a bucket of tapwater, wash it off with a hose or wipe it off with
a cloth).
 Unscrew the sensor from the SACIQ (SW) sensor connection cable.
 Always place a protective cap on the plug head of the sensor and on
the SACIQ (SW) sensor connection cable so that no moisture or dirt
can get into the contacting surfaces.
 In corrosive environments close the dry socket of the sensor
connection cable with the SACIQ-Plug protective screw cap in order
