Method for detecting the correct rotational direction of a centrifugal apparatus, and a centrifugal apparatus assembly

摘要

A method for detecting the correct rotational direction of a centrifugal apparatus, the method comprising steps of: rotating the centrifugal apparatus in a first direction; acquiring first frequency data relating to the step of rotating the centrifugal apparatus in the first direction; rotating the centrifugal apparatus in a second direction, the second direction being opposite to the first direction; acquiring second frequency data relating to the step of rotating the centrifugal apparatus in the second direction. The method further comprises a step of detecting the correct rotational direction of the centrifugal apparatus based on comparing the first frequency data with the second frequency data, the comparison being carried out in respect of at least one significant frequency range, wherein in each of the at least one significant frequency range a smaller magnitude is interpreted as indication of the correct rotational direction.
