If all four wheels for one vehicle are the same and being balanced, then parameters only need to be input one time. If you turn off the machine, the wheel parameters are forgotten and must be entered again.

After placing the weight, close the hood and spin the wheel. The following screen will appear: You have now zeroed out the balance for the outside of the rim.

However, because I had the “least unbalance value setting” on .70 Ounces, the machine ignored the remaining .20 ounces because it was less than .70 ounces. .20 Ounces may or may not make a significant difference depending on the size of the wheel and rim.
