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.

titrator (observe the routing of the cable).
2. Place a magnetic stirring bar into a titration cell.
Place a titration cell over the magnetic stirrer.
3. Place the rubber ring on the stand rod to set the minimum height of
the electrode holder.
