For example: Maximum speed 4000 RPM, density 1.6 kg/dm³
If, in exceptional cases, the maximum load indicated on the bucket is
exceeded, the speed must also be reduced. The permissible speed can
be calculated using the following formula:
For example: Maximum speed 4000 RPM, maximum load 300 g, actual
load 350 g
Please contact the manufacturer if you are not sure.
The centrifuging radius must be entered in centimetres.

If the rotor has been changed, the centrifugation run is cancelled after
rotor detection. The rotor code (red) is displayed.
■
If the maximum speed of the rotor used is less than the set speed, the
speed is limited to the maximum rotor speed.
The audible signal sounds:
■
after a problem occurs in the 2 s interval.
■
after completion of the centrifugation run and rotor standstill in the 30 s
interval.
Opening the lid or pressing any button stops the audible signal.
