If the program location indicator flashes, this program location is
already assigned centrifugation data. In this case, set a free program
location, or overwrite the centrifugation data by continuing.

The buffer includes the program locations "----" and 90 to 99.
Changed centrifugation data is automatically saved to program location
"----" every time a centrifugation run is started.
The changed centrifugation data, of the last 11 centrifugation runs, are
stored in the buffer and can be retrieved.
■
Rotor detection is performed after starting a centrifugation run.
■
If the rotor has been changed, the centrifugation run is cancelled after
rotor detection. The rotor code (R) and the maximum rotor speed (n-
max) of the newly detected rotor are displayed.
■
If the maximum speed of the rotor used is less than the set speed, the
speed is limited to the maximum rotor speed.
For centrifuges with the heating/cooling option, the temperature setpoint
can be adjusted from -20 °C to +90 °C. If the actual temperature deviates
from the set temperature by more than 5 °C, this is signalled by a flashing
temperature value indicator.
The lowest achievable temperature is rotor dependent.
The centrifuging chamber is cooled to the preselected temperature when
the rotor is at a standstill and the lid is closed. The display shows the
temperature setpoint.
For rapid precooling of the unloaded rotor and accessories, we recommend
a centrifugation run with the continuous operation settings and a speed of
approx. 20% of the maximum rotor speed.
During the centrifugation run, the centrifuging chamber is heated to the
preselected temperature if required. The heating is switched off when the
rotor is at a standstill.
