Ready to balance a wheel
NOTE:
Calibration is required when the wheel balancer is first put into
operation at a fixed location, after it is moved to a new location or when
the technician suspects the machine of providing incorrect values or
when main components have been replaced. It is recommended to
perform a calibration every 3 month, but especially while having
enormous possible changes of temperature during the seasons. See the
detail procedure in the calibration section.
