Commissioning
Fig. 3-2 Measurement electrode or compensation electrode with storing aids
In the delivery condition, each electrode is equipped with a watering
cap and a nut that protects the screw-in thread. Prior to installation, first
remove the watering cap and, using the special hexagon key, unscrew
the electrode from the nut. Keep both storing aids in case you want to
store the electrode.
Caution
The membrane of the electrode must not
 dry up (follow notes on storage)
 be damaged
 be brought into contact with grease.
Notes on storage If you will not use the electrode for a longer period of time, screw the
electrode into the nut as far as it will go. Soak the foam insert in the
watering cap with VARiON
®
/ES-1 standard solution (lower
concentration) and plug the electrode into the watering cap.
Caution
Make sure to use the correct solution for the watering cap
(VARiON
®
/ES -1 standard solution). If you use the watering
solution of the reference electrode instead the function of the
electrode can be seriously damaged.
