900 Touch 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
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.
