6.3.2.6
Speed
The set speed of the centrifuge is displayed in the upper area of the speed
field. The actual value is displayed right below. The speed is stated as the
number of revolutions per minute (rpm). The speed/RCF values are
interdependent (see chapter 2.2.2.1 - "Speed, radius, and relative
centrifugal force"). The maximum speed values depend on the rotor that is
used.
It is also possible to change the RCF value during a centrifugation run.
Fig. 14: Setting the speed
Changing the speed increments
By default, the speed is changed in intervals of 100 rpm.
To change the speed in intervals of 1 rpm:
• Keep the stop key pressed while setting the desired speed with the right
function knob.

6.3.2.7
Relative centrifugal force (RCF)
The set RCF value of the centrifuge is displayed in the upper area of the
RCF field. The actual value is displayed right below. The RCF value is
stated as a multiple of the gravitational acceleration (x g). The values of
speed and RCF are interdependent (see chapter 2.2.2.1 - "Speed, radius,
and relative centrifugal force"). The maximum speed/RCF values depend
on the rotor that is used.
The parameter RCF can be changed during the centrifugation.
Abb. 15: Setting the RCF-value
Changing the RCF increments
By default, the RCF value is changed in intervals of 10 x g.
To change the RCF value in intervals of 1 x g:
• Keep the stop key pressed while setting the desired RCF value with the
right function knob.
