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.
If the permissible weight difference was exceeded within the rotor load, the centrifugation run is aborted during
start-up and the following will appear on the display:
>RCF< RPM t/min:s
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,
however, only apply to the current centrifugation run and are not saved.
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:
>RCF< RPM t/min:s
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.
