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 prevents
the reference electrode from coming into contact with the cleaning
solution. However, it is also possible to clean the silver counter
electrode in a beaker.
NOTE
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 dan-
ger can arise if the RA 600 is used correctly.
Variant 1:
Cleaning the silver
counter electrode with
the RA 600
cleaning attachment
NOTE
Never lubricate with oil or grease the inner O-ring in the RA 600 clean-
ing 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 cap.
