Centrifugation

Starting centrifuge program
Press the START key on the control panel. The centrifuge accelerates to the pre-set speed with

Please enter a new value.
You cannot open the lid as long as the centrifuge is running.

The run will terminate.
Check the loading and start the centrifuge once again. See the information on proper loading in the
rotor instruction manual. For information on troubleshooting, see section
