The method is for calibrating a shaft encoder, which provides an indication of the angular position of a shaft, and involves the use of stored sine and cosine values as used in a wheel balancing system. Angular position data containing a reference indication and information about the increasing angular value are stored in an RAM associated with a processor. As the shaft is turned, angular position data is reproduced from the memory and the angle values monitored and compared with the stored values. It is determined whether a define number of angle values occurs between each reference value and whether the values occur in a defined sequence for a partic. direction of shaft rotation. The stored data is updated using the current information.
