3 Cleaning
Exterior cleaning Remove water-soluble contamination by rinsing with deionized water. Other
types of contamination have to be removed as follows while the contact time
with the detergents should be kept as short as possible:
Thoroughly rinse the multi-parameter probe with water after this.
Cleaning the
pressure sensor
To clean the pressure sensor, remove the screen lid with your fingernails.
Then rinse the recess with a mild water jet (e.g. wash bottle or slightly-
running faucet).
NOTE
The membrane of the depth sensor is very sensitive to mechanical
impacts. Therefore, avoid any touching of the membrane. Do not point
a sharp water jet at the membrane while cleaning it.
Please observe the instructions on cleaning the sensors given in
the respective sensor operating manuals. If necessary, remove
the sensor for cleaning and close its plug-in position with a blind
plug.
