Translation of the original operating manual
If the standstill heating is activated, the centrifuge starts to preheat after it is
switched on. In the runtime field, the symbol " " is displayed. The lid must
be closed.
NOTE
The centrifuge is equipped with the "RAPID_TEMP" program. This
program is used to precool the rotor chamber quickly under defined
conditions (see chapter 6.3.2.5 - "
Standard menu
", Program list).
Radius
The radius determines the value of the relative centrifugal force (RCF) that
the sample is subjected to. Normally, the maximum RCF value is displayed.
If the value is reduced manually, a downward facing arrow ( ) will be
displayed in the RCF field.
Density
This setting is useful for glass vessels. If the density of the liquid to be
centrifuged is higher than 1.2 g/cm
3
, the value must be adapted manually.
This will reduce the maximum possible final speed (see chapter 2.2.2.2 -
"
Density
"). A downward facing arrow ( ) will be displayed in the speed
field. Values between 1,2 and 10.0 g/cm
3
are possible.
Centrifugation monitoring
The centrifugation monitoring function enables the continuous monitoring of
the speed and runtime parameters during the centrifugation.
• Activate the centrifugation monitoring function by clicking.
NOTE
If the function is activated during a centrifugation run, the monitoring
process will not be started until the start of the next centrifugation run.
The centrifugation monitoring function compares the speed values of the
current run with the reference values that are stored in the control unit.
After every run, it issues a corresponding message. The runtime is
considered faulty if the centrifugation run had to be stopped prematurely.
