This program should be run whenever the settings appear to be out of tolerance or
when the machine requests self-calibration spontaneously by displaying the "Err CAL"

- Set the machine for balancing truck wheels (TRUCK light on)
- Fit a wheel of average dimensions (es.: 8"x22,5") preferably with only small

(10 oz).
The automatic calibration procedure concludes with display of the wheel imbalance
values (which do not consider the sample weight applied).
