Take the exact measurements of the wheel mounted as described in ▪
DATA SETTING
.
P RESETTING OF INCORRECT DIMENSIONS WOULD MEAN THAT THE MACHINE IS NOT CORRECTLY CALIBRATED , THEREFORE
ALL SUBSEQUENT MEASUREMENTS WILL BE INCORRECT UNTIL A NEW SELF - CALIBRATION IS PERFORMED WITH THE CORRECT
DIMENSIONS !
Perform a manual spin under normal conditions ▪
Add a sample weight on the outside in any angular position. ▪
Sample weight: 60 g. (2.00 .oz) for car
300 g. (10.0 .oz) for truck
Shift the sample weight from the outside to the inside keeping the same angu ▪

position.
Turn the wheel until the sample weight is in the 12 o’clock position ▪
