Centrifugation

In accordance with EN / IEC 61010-2-020, no persons, hazardous substances or objects may be within a
safety range 300 mm around the centrifuge during a centrifugation run.
After each centrifugation run, while the lid is unlocking, the remaining number of running cycles (centrifugation
runs) will be briefly displayed.
Example:
PROG RPM
If the permissible weight difference within the rotor load is exceeded, the centrifugation run is aborted during
the start-up and the following display appears:
PROG RPM
A centrifugation run can be aborted at any time by pressing the
During a centrifugation run, centrifugation parameters can be selected and changed. The changed values are
stored at program location #.
RCF
With the key, you can toggle between the RPM display (RPM) and RCF display ( RCF ) at any time. If
the RCF display ( RCF ) is worked with, the centrifuging radius must be input.
The following is displayed:
PROG RPM
Further operation of the centrifuge is then only possible after opening the lid.
Operation errors and malfunctions will be shown (see the chapter on "Malfunctions").
 Plug in the mains switch. Switch position .

Load the rotor and close the centrifuge lid.

needed. The LED above the key is
illuminated if the RCF display ( RCF ) is
activated.

 Input the desired centrifugation parameters (see the
"Programming" chapter).

 Press the key.
START
PULSE The centrifugation run is started.
During the centrifugation run, the rotor
