I had the same problem. If you contact Hunter, they have local reps who can come to you (for a fee) and calibrate the machine. I didn't want to spend the money, so instead I took a wheel and tire, marked the location on the spindle, ran it on the balancer, noted the location and weight of the required balance weights, then clocked the wheel 180 deg on the spindle and ran it again. The new balance weight and location were close enough to those from the first time that I called it good.
If you want to get really sophisticated, flip the wheel over and do this test again.
