28.11.3.4 Stirrer
The parameters for the stirrer are edited under [Stirrer].
Stirrer
Selection of the MSB connector the stirrer is connected to. The selection
does not depend on the number of MSB connectors of the control device.
Selection 1 | 2 | 3 | 4 | off
Default value 1
off
No stirrer will be used.
Stirring rate
Setting the stirring rate. It can be set in steps of –15 to +15. The default
setting 8 corresponds to 1000 rpm. The formula for calculating the rota-
tional speed is specified in chapter 31.3, page 407. 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
Input range –15 - 15
Default value 8
Switch off automatically
on | off (Default value: on)
If this parameter is activated, the stirrer will be switched off automatically
at the end of the titration, measurement, etc.
