Relative centrifugal force (RCF) and centrifuging radius (RAD)

15.3.1

Centrifuging radius (RAD)

•
Keep pressing the
RCF
The LED is lit in the key.
•
Use the adjusting knob
By changing the centrifuging radius, the value adjusts automatically to the RCF.
•
Press the key, to have the settings applied to the display.

15.3.2

Relative centrifugal force (RCF)

The relative centrifugal force (RCF) depends on the radius of the centrifuge. Before setting the RCF, the
radius of the centrifuge must be set. See chapter "Centrifuge radius (RAD)".
•
Keep pressing the
RCF
The LED is lit in the key.

Programming

If parameters are changed, the program place number is displayed in parentheses (). This means that the
centrifugation data in the display no longer corresponds to the centrifugation data from the program place that
has been saved.
