5.3.5 Setting the 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:
(i) Turn the left rotary knob until “set” appears in the display field in front of the parameter "Temp".
(ii) Select the option by pressing or turning the right rotary knob. "Set" will now flash.
(iii) Turn the right rotary knob until the desired value is displayed.
(iv) 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.
• If the set temperature is above the actual temperature, it will be represented by one single bar on
the temperature scale.
• If the set temperature and the actual temperature are identical, the line of bars of the scale will be
shown completely.
