Parameter description
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 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
NOTE
If a stirrer is used in the determination run, it can nevertheless be con-
trolled manually at the same time. For example, you can use the man-
ual control to reduce the stirring rate of a stirrer which has been started
in the determination run.
