During the centrifugation run, the speed of the rotor or the RCF value resulting from this, the sample temperature (for
centrifuges with cooling only) and the remaining time will be displayed.

Changing settings during the centrifugation run.

The running time, the speed, the relative centrifugal force (RCF/RZB), the run-up and run-down parameters as well
as the temperature (for centrifuges with cooling only) can be changed while the centrifuge is running.
The parameters can only be changed one at a time and in succession.
