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

Put the samples in a long sock and swing it round your head for an hour.
That should isolate the platelets from the plasma, or drop out the precipitate or whatever it is you're doing.
