Speed / relative centrifugal force (RCF)
The set speed of the centrifuge is displayed in the upper area of the
Speed/RCF field. The actual value is displayed right below. The speed is
stated as the number of revolutions per minute (min
-1
= rpm) and the RCF
values as a multiple of the gravitational acceleration (x g). The values 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 parameters speed and RCF can be changed during the centrifugation.

Runtime
The set runtime is displayed in the upper section of this field, with the
remaining runtime shown below. The runtime is counted down from the set
value, starting with the start of the centrifuge and ending with the start of
the deceleration phase. The maximum runtime is 99 h:59 min:59 sec. As of
59 min:59 sec, the unit switches from "h:min" to "min:s".
The parameter runtime can be changed during the centrifugation.
NOTE
If the runtime is changed during an active centrifugation run, the time that
has already elapsed will not be taken into consideration. The centrifuge
will perform a complete run with the new runtime.
