1 Wipe the silver counter electrode with a lint free paper towel
and carefully remove any loose deposits.
2 Fill a beaker (150 ml, high-sided form) with approx. 25 ml RL-
AG/Oxi cleaning solution.
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.

solution to just above the silver counter electrode.
