Product description

This Calibration Weight is specifically designed for the "Proof Rotor" test on professional Snap-On wheel balancers. The proof rotor is a master test device used to verify the integrity of the balancer's entire measurement system, including the spindle, bearings, and electronic sensors. This specific weight is attached to the rotor during the test to simulate a known imbalance. If the balancer does not report the exact mass and position of this weight during the test, it indicates a mechanical or electronic fault that must be addressed. Using this precise calibration weight is the only way to certify that your balancer is performing to original factory specifications.

Product highlights
