Centrifugation
Once the rotor has been properly installed, the main switch has been turned on and the lid has been
closed, you can start centrifuging.
Starting centrifuge program
Press the START key
on the control panel. The centrifuge accelerates to the pre-set speed with the
time display active.
If the speed setting is higher than the maximum permissible speed or RCF-value for the particular
rotor, then the display will show the message CHECK SET SPEED. The centrifuge decelerates. Please
enter a new value.
You cannot open the lid as long as the centrifuge is running.
Imbalance indicator
If a load is imbalanced, this will be indicated at speed higher than approx. 300 rpm by the message
"Imbalanced load".
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

key
, you can open the lid and remove the centrifuge material.
You can also stop the centrifuging program manually at any time by pressing the STOP key
