5.1 Temperature
During centrifugation, heat is generated by air friction between the rapidly
spinning rotor and the air inside the rotor camber.
The temperature rise depends on the rotor ( swing-out or angle rotor ),bucket type,
ambient temperature, running time and the speed of the rotor.
The continous air flow through the centrifuge housing is restricting the
temperature rise of the samples to the standard value of 40°C with each rotor even
at maximum speed.

6.1 Imbalance
In case of unequal loading of opposite buckets/tube racks or tube-holes, the
operation will be interrupted during the acceleration phase. The rotor will be
decelerated to standstill. Additionally the error message "ERROR" appears on the
preset display "speed".
If the actual display "speed" shows error no. 1, the difference in weight of the
samples is too big. Fill the tubes and load the rotor as described under point 3.
If the actual display "speed" shows error no. 2, there can be several reasons for:
- The imbalance switch is not adjusted correctly.
- The imbalance switch is defective.
