Calibrate when detecting that the setting condition is out-of-tolerance or when the ma-
chine so requires as the E 1 message is displayed.
Calibrate as follows:
1. select the sensitivity calibration icon
2. fit a wheel of average dimensions (diameter no less than 14") on the wheel balancer
with only a small unbalance;
3. perform a spin;
4. at the end of the spin, fix the calibration weight supplied with the machine on the
swinging unit bell as indicated in figure 25;
5. perform a second spin;
6 at the end of the spin, change the position of the calibration weight on the shaft
assembly bell as indicated in figure 25a;
7. perform a third spin. This last calibration phase includes the execution of three
consecutive spins in automatic mode.
If the calibration has been successful, a permission acoustic signal goes off at the end
of the spin; otherwise, the E 2 message is temporarily displayed.
Notes:
- Once the procedure is finished, remove the calibration weight;
- Press the button to interrupt the calibration procedure at any time;
- This calibration is valid for any kind of wheel.
Calibration of the ultrasonic width sensor (if installed)
Used to calibrate the ultrasonic sensor located on the wheel guard pipe (width). It must
be performed when the machine requests it by displaying the E4 message, or when the
measured and the actual rim widths differ.
- select the ultrasonic width sensor calibration icon
