Change the settings during the centrifugation run

It is not possible to modify settings during centrifuge operation if program linkages are being used.
The running time, the speed, the relative centrifugal force (RCF), the centrifuging radius, 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.

Acoustic signal

The acoustic signal sounds:
•
Upon the appearance of a disturbance in 2 second intervals.
•
After completion of a centrifugation run and rotor standstill in 30 second intervals.
The acoustic signal is stopped by opening the lid or pressing any key.
The signal after completion of the centrifugation run can be activated or deactivated in the following manner, if the
rotor is at standstill:
•
Keep the key held down for 8 seconds.
