Abstract
Automatic checking of the calibration of a vehicle wheel balancer includes putting the balancer in a calibration check mode, mounting a test weight of known mass to a hub of the balancer, spinning the hub with the said test weight mounted thereon to determine the imbalance of the rotating hub/test weight assembly, comparing the determined imbalance with an expected imbalance and determining the difference therebetween. The balancer displays a message indicative of the status of the balancer's calibration. The balancer calibration check may be optionally overridden.
