4. MACHINE CALIBRATION
To operate the machine properly, it must be calibrated. Calibration allows storing the mechanical and
electrical parameters specifi c to each machine so as to provide the best balancing results.
4.1 When to carry out machine calibration
Table T4 lists the cases in which machine calibration should be carried out. Calibration must be carried out
whenever one or more of the conditions listed are active.

The machine requires two independent calibrations:
• Calibration for the CAR/SUV Wheel Type (calibration is the same for both types of wheels);
• Balancing for the MOTO Wheel Type (wheels for motorbikes).
It is not compulsory to run both calibrations. If, for example, a user uses the machine exclusively for motorbike
wheel balancing, he must perform calibration only for the MOTO Wheel Type. Similarly, if the user uses the
machine exclusively to balance auto-vehicle/off-road wheels (CAR/SUV), he must run calibration only for
the CAR/SUV Wheel Type.
If the user instead uses the machine to balance all Wheel Types, he must run both calibrations. It does not
matter the order in which the two calibrations are performed.
4.2 Calibration according to the CAR/SUV Wheel Type
The calibration for the CAR and SUV Wheel Types is the same.
To perform machine calibration, you must fi rst provide for the following material:
• a balanced wheel with steel rim that has the following dimensions: Diameter 15” Width 6”. The distance of
the wheel from the machine should be approximately 100 mm. You can also use wheels with dimensions
similar to those recommended as long as the difference is minor. It is not possible to use wheels with rims
in aluminium;
• A 50 gram weight (preferably in iron or zinc).
