What to do if the parameter arm on my John Bean VPI System Wheel Balancers is not measuring rim distance?
If the parameter arm isn't measuring rim distance, and the machine locks up, it could be due to a malfunction in the parameter arm itself, caused by an electrical system failure or a loose harness connection. You can either replace the parameter arm or manually enter the parameters to continue using the machine.
