3. Close the centrifuge door.
4. Restart the centrifuge.
The refrigeration starts operating if the pre-selected temperature is below the current temperature
of the rotor chamber.
Pre-warming or Pre-cooling the Centrifuge
In order to pre-temp the centrifuge and the unloaded rotor proceed as follows:
1. Press the
key.
An indicator above the
key indicates operation at the activated pre-temp function.
2. Enter the desired value by pressing the key
under the right display repeatedly, until the
desired value shows.
You increase or decrease the temperature in steps of 1
°C.
3. Press the
key.
The rotor will be operated at optimal speed.
Changing the settings during the run
You can change the settings during the run as follows:
1. Press one of the three
keys in the control panel.
The current value will switch into the pre-selecting value mode.
2. Enter the new value as described above.
Note
When you press a different key than the
key you will quit the pre-temp function.
Note
If you wish to change the temperature of your samples, please consider that the time required for
temperature adjustment is prolonged. For critical applications you should take other precautions to
ensure that the desired temperature is actually reached and maintained.
