Installation of the titration stand
The titration stand consists of a holder onto which the electrode, titration
cell and magnetic stirrer are attached. The titration is performed in the
titration cell.
1. Place the magnetic stirrer onto the base of the titration stand
(observe the routing of the cable).
2. Place a magnetic stirring bar into a titration cell.
Attach the titration cell to the magnetic stirrer.
3. Place the rubber ring on the stand rod to set the minimum height of
the electrode holder.
4. Press the button to lock the electrode holder and place the
electrode holder on the stand rod.
The electrode holder is locked upon release of the button.
5. Remove the white cap from the tip of the electrode.
Insert the electrode into the electrode holder.

Warning against system damage
Make sure that the height setting of the electrode holder protects the electrode
against damage from the stirring bar and against contact with the bottom of the
titration cell.
Keep the lock button pressed whenever the electrode holder is being moved.
Note: Whenever the electrode is taken from the titration stand or the
titration cell is removed from the titration stand, always place a container
beneath the electrode. Otherwise, drips from the sample or chemicals
could contaminate the work area.
