Translation of the original operating manual
Press the right function key to confirm the selected value. If this
is not done, the value will be automatically reset to the last
setting.

Temperature preselection
The temperature scale shows the actual temperature in the rotor
chamber. f the selected temperature (= set temperature) is
below
the
actual temperature, the set temperature will be represented by a
flashing bar on the temperature scale (Fig. 6.12).
Fig. 6.12:
Set temperature below
actual temperature
If the set temperature is
above
the actual temperature, it will be
represented by one single bar on the temperature scale (Fig. 6.13).
Fig. 6.13:
Set temperature above
actual temperature
If the set temperature and the actual temperature are identical, the
line of bars of the scale will be shown completely.
Precooling
Depending on the substances to be centrifuged, it may make sense
to precool the centrifuge. The precooling prevents the cooled samples
in the uncooled centrifuge from heating up to an inadmissible
temperature.
Unmoved air in the rotor chamber distorts the measuring and control
behavior and causes the compressor to freeze overs. At
temperatures below 0°C, aqueous liquids will freeze, making
sedimentation impossible.
Ensure that the rotor temperature will not fall below 0 °C if it is at
a standstill!
