Note
The setting of the stirring rate under Menu ▶ Parameters ▶ Automa-
tion applies only for stirring during the immersion of the electrode in
the rinsing beaker. The stirring rate during the determination is set

Dripping time
Waiting time after the titration head moves out of the sample beaker and
out of the rinsing beaker.
Range 0 ... 999 s
Default value 3 s
Rinsing time
Waiting time during which the electrode remains immersed in the rinsing
beaker.
Range 0 ... 999 s
Default value 5 s
Stirring rate
Setting the stirring rate. It can be set in steps of –15 to +15. The default
setting 8 corresponds to 1000 U/min. The formula for calculating the rota-
tional speed is specified in chapter 10.2, page 140. The optimum stirring
rate can be tested in the manual control.
The algebraic sign of the stirring rate changes the direction in which the
stirring is done. When the stirrer is viewed from above, this means:
￭ "+": counterclockwise rotation
￭ "–": clockwise rotation
Range –15 ... 15
Default value 8
