Malfunction and Maintenance
6.2.1 Electrolyte Replacement
It is recommended to replace the gel electrolyte at least twice a year or when an adjustment is no longer possible due to
readings that are unstable or too low.
Carry out the following steps one after the other:
1. Unscrew the membrane cap.
2. Use the tweezers to remove the G-holder from the membrane cap.
3. Empty the gel electrolyte from the membrane cap.
4. Rinse the electrode finger with tap water.
5. Shake the sensor body dry several times so that the pressure equalization opening [1] is emptied (see figure).
6.2.2 Membrane cap replacement
It is recommended to replace the membrane cap once a year or when an adjustment is no longer possible due to readings that
are unstable or too low.
The new membrane cap is supplied with the G-holder. To replace the membrane cap, please follow the commissioning proce-
dure (see chapter 3.1).
6. Place the special sandpaper on a paper towel.
7. Hold the sensor upright.
8. Hold the special sandpaper and run the tip of the working electrode at least twice over it. Use a new surface of sandpaper
each time (see figure).
