The method involves determining the actual difference between the angular setting of at least one marker (152) on the transducer wheel (150), which is connected to a first shaft, and the angular setting of a reference transducer wheel attached to a second shaft. The actual difference is compared with a desired difference and the deviation is stored as a construction error for the transducer wheel.
