6. MACHINE CALIBRATION
To function properly, the machine must be calibrated. Calibration allows storing the mechanical and electrical parameters specific to
each machine so provide the best balancing results.
6.1 When to carry out machine calibration
Table T6.1 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.

Who must perform it
When the machine is installed at the final user
Mandatory
Technical Service
When the CPU-C1C.X electronic circuit board is replaced
Mandatory
Technical Service
When a mechanical part linked to the pick-up signals (pick-up, pick-up
compression springs, suspension unit + shaft) is replaced
Mandatory Technical Service
When the pick-up compression springs adjustment are modified

When the encoder disc is replaced
Mandatory
Technical Service
When a different motorbike adaptor is used since the last calibration
for MOTO Wheel Type
Mandatory Final user and/or Technical Service
When the machine doesn’t show accurate results for balancing
Recommended
Final user and/or Technical Service
When there are wide and constant variations due to environmental
humidity and temperature (for example seasonal changes)
Recommended Final user and/or Technical Service
A non-calibrated machine provides balancing results equal to 0 grams (0.0 ounce).
6.2 Machine calibration for the CAR/SUV Wheel Type
To perform the machine calibration it is necessary to use a balanced complete wheel with steel rim with the following dimensions:
• Diameter: 15”.
• Width: 6”.
• Distance: as close as possible to 100 mm.
It is also possible to use a wheel with dimensions similar to those indicated, provided that the difference is not excessive. Aluminum
wheels cannot be used to calibrate the machine.
