9.2 Installation of electrodes
On top of the electrodes, coloured markings are provided for
easier assignment:
• Potentiostatic electrode: green
• pH single-rod electrode: white
• Redox electrode: brown.
9.3 Checking magnetic stirring stone and filling in
cleaning ball
1. Unscrew the protective cap (pos. C) at the flow fitting (pos. F).
2. Remove the tube part (transport protection) from the drilled
hole.
9.3.1 Visual inspection of magnetic stirring stone
1. Remove the position stabiliser from the magnetic stirring
stone.
The position of the magnetic stirring stone might be changed by
vibrations of the flow fitting during transport.
2. Check if the magnetic stirring stone is still seated flat on the
lower edge of the screw
part.

Adding
the cleaning balls
• Cut off about 3-4 mm of one edge of the cleaning balls packet,
and carefully fill the 15 balls into the hole (pos. C) of the
potentiostatic electrode (pos. E).
Warning
Switch off the power supply before installing.
Warning
The reagents must not come in contact with the eyes
or skin. Wear protective gloves and glasses when
performing the following steps!
Note
The housing of the measuring cell must not come
into contact with the reagents. There is a risk of
corrosion and cloudiness.
Caution
To prevent a siphon effect, the sample water outlet
must flow freely downwards without
counter-pressure!
