Entering centrifugation parameter

If no key is pressed for 8 seconds long after the selection or during the input of parameters, the previous
values will be shown in the display. The input of parameter then has to be executed again.
Select the RPM or RCF display with the key

A centrifugation run can be stopped at any time by pushing the key
All parameters can be selected and altered during the centrifugation run (see Chapter "Entering centrifugation
parameter").
You can switch-over at any time between the RPM and RCF display with the key
centrifugation radius is necessary if you are working with the RCF display.
If OPEN OEFFNEN is displayed, a further operation of the centrifuge is only possible after opening the lid
once.
If R xx n-max xxxxx is displayed, then no centrifugation run has taken place as the rotor was changed
beforehand, refer to Chapter " Rotor Identification ".
Turn on the mains switch. Switch position .
Load the rotor and close the centrifuge lid.
