Fig. 3-2 Measurement 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.
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 concentra-
tion) and plug the electrode into the watering cap.
The membrane of the electrode must not
 dry up (follow notes on storage)
 be damaged
 be brought into contact with grease.
