Note
The protection hood can be screwed on for transport or storage even if the
watering cap is plugged on. Please follow the notes on the storage of the
electrode in the operating manual of the electrode.
3 Pull out the blind plug (pos. 3).
4 Prepare the electrode (pos. 4):
– Make sure that both O-rings (pos. 5 and 6 ) are mounted, clean
and dry.
– Remove the watering cap (pos. 7) and dab dry the shaft of the
electrode with a clean paper towel.
– Position the coupling ring (pos. 2) on the shaft of the electrode.
– Plug on the watering cap (pos. 7) to protect the electrode for the
time of the installation.
5 Insert the thus prepared electrode (pos. 8) in the electrode
receptacle:
– Position the electrode at the opening and, against the pressure of
the air cushion inside, slowly push it in approx. 2 cm, until the air
escapes and the counter pressure is noticeably reduced.
– Then push in the electrode as far as it will go and turn it until the
electrical plug connection locks in place using light pressure. The
electrode is completely inserted when it cannot be turned any
more.
6 Screw on the coupling ring (pos. 2) by hand to the limit.
7 For calibrating and measuring remove the watering cap.
8 Screw on the protective hood (pos. 1 in Fig. 3-2).
