Abstract: A method for classifying a specific pipetting procedure of a laboratory automation device comprises: determining a plurality of pressure curves of a plurality of pipetting procedures, which are equivalent to the specific pipetting procedure; determining a median curve from the plurality of pressure curves, wherein for each time point of the median curve, a median value of the values of the plurality of pressure curves at this time point is calculated; determining a median curve range containing the median curve; controlling the laboratory automation device to perform the specific pipetting procedure and measuring a specific pressure curve during the specific pipetting procedure; determining a deviation value of the specific pressure curve with respect to the median curve range, wherein the deviation value is indicative of the specific pressure curve leaving the median range; and classifying the specific pipetting procedure as erroneous, when the deviation value is greater than a threshold.
