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 titration stand on the right side (syringe side) of the 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.
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.
4 Screw the syringe tip onto the valve.
Place the attachment sleeve into the bracket.
5 Screw the piston onto the dosage arm.
6 Fix the syringe cover with six screws.
