Abstract: A method of calibrating an electronic wheel balancer includes mounting a calibration wheel on the balancer shaft, the calibration wheel including mounting pins configured to engage mounting holes on a face plate. The balancer emits a visible towards the calibration wheel, the beam indicating a home position for an inner plane calibration weight on the calibration wheel. The calibration wheel is rotated to the home position and an inner weight plane calibration weight is attached to the calibration wheel. The balancer shaft is automatically rotated to obtain sensor data from force transducers on the balancer. Using the sensor data, the balancer automatically calculates and stores inner weight plane reference data. The motor shaft is stopped and the inner plane calibration weight is moved to an outer weight plane position on the calibration wheel.
