5.4.2 Cleaning the silver counter electrode
We recommend to clean the silver counter electrode with the RA 600
cleaning attachment that is available as an accessory (see section
5.8 M
AINTENANCE EQUIPMENT AND REPLACEMENT PARTS ). This avoids
the reference electrode coming into contact with the cleaning solution.
However, it is also possible to clean the silver counter electrode in a
beaker.
Caution
The reference electrode must not come into contact with the
cleaning solution under any circumstances. This could destroy
the reference electrode and cause the sensor to become
defective. However, no danger can arise if the RA 600 is used
correctly.

cleaning attachment
Caution
Never grease or lubricate the inner O-ring in the RA 600 cleaning
attachment!
1 Wipe the silver counter electrode with a lint-free paper towel
and carefully remove any loose deposits.
2 Screw the cleaning attachment onto the sensor, instead of the
membrane head.
