Using the number pad, one or more of the wheel
dimensions can be changed.
- The wheel balancer prepares for manual entry
of the distance.
- Using the number pad, change the distance
displayed by entering the distance measured
with a tape measure between the right edge of
the body and the inner edge of the rim (Fig. 20).
- press the
confirm and switch to the width value entry
phase;
- Change the displayed value to the value
measured using the manual calliper (Fig. 21).
- press the

3. Suite WHEEL DIAGNOSIS PROGRAMME
3.1. Radial and lateral runout measurement
This function is used to determine the causes of
disturbance (vibration) generated by geometric
deformation of the rim and/or tyre, which may still
persist even after a thorough balancing procedure.
The machine indicates that the procedure needs
to be performed by displaying the following war-
ning light
to perform the procedure whenever considered
necessary.
To do this, perform a spin.
If a wheel assembly is mounted, the following
icons are displayed on the screen at the end of
the spin indicating:
-
the radial run-out of the wheel (1st harmonic);
-
the radial run-out of the wheel peak-to-peak;
-
the lateral run-out of the wheel (1st harmonic);
-
the lateral run-out of the wheel peak-to-peak;
