5.3.4 Temperature
The temperature of the centrifuge is controlled by a refrigeration unit.
Temperatures between -10 °C and + 40 °C can be preselected.
To preselect the temperature in steps of 1 °C:
•
Turn the left rotary knob until “set” appears in the display field in front of the
parameter "Temp" (Fig. 5.15).
•
Select the option by pressing or turning the right rotary knob. "Set" will now
flash.
•
Turn the right rotary knob until the desired value is displayed.
•
Press the right rotary knob to confirm the selected value. If this is not done,
the value will be automatically reset to the last setting.
The temperature scale shows the actual temperature in the rotor chamber.
•
If 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. 5.16).
•
If the set temperature is above the actual temperature, it will be represented
by one single bar on the temperature scale (Fig. 5.17).
•
If the set temperature and the actual temperature are identical, the line of
bars of the scale will be shown completely.
The temperatures that can be reached depend on the rotor type, speed, and
ambient temperature.
