Abstract

An automatic calibrator is provided in combination with a wheel aligner used in determining the toe angle and camber angle of a wheel. A target is connected to the wheel aligner to move therewith. When the wheel aligner is at a predetermined angle, the target is used to provide a signal indicating that the wheel aligner is at the predetermined angle. A transducer output signal is then checked to determine if the transducer output signal accurately corresponds to the predetermined angle.
