4. MACHINE CALIBRATION
To operate properly, the machine must be calibrated. Calibration allows storing the mechanical and electrical parameters specific to
each machine so as to provide the best balancing results.
4.1 When to carry out machine calibration
Table T4.1 lists the cases in which machine calibration should be carried out.
Table T4.1: Conditions for carrying out machine calibration
Condition Status Who must perform it
When the machine is installed at the final user. Mandatory Technical Service
When the 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. Mandatory Technical Service
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
The machine requires two independent calibrations:
•
Calibration for the CAR/SUV Wheel Type (calibration is the same for both types of wheel);
• Calibration for the MOTO Wheel Type (wheels for motorbike).
It is not mandatory to perform both calibrations. If the user exclusively uses the machine to balance auto-vehicle/off-road wheels
(CAR/SUV) he must perform only calibration for the CAR/SUV wheel type.
4.2 Machine calibration for the CAR/SUV Wheel Types
Calibration for the CAR and SUV Wheel Types is the same. To perform machine calibration, you must first provide for the following
material:
• A balanced wheel (complete with rim and tyre) with steel rim and with the following dimensions: 14” ÷ 16” diameter: 5”
÷ 5.5” width. Do not use wheels with aluminum rims.
•
A 50-gram weight (preferably made of Iron or Zinc).
To calibrate the machine, proceed as described below:
