For calibration of the machine, proceed as follows:
- Use a medium-sized metal wheel. Example: 6" x 14" (± 1")
- Preset the wheel dimensions with GREAT CARE.
- Follow the instructions appearing on the monitor.
7.4.3 - AMBIENT TEMPERATURE
Ambient temperature is important for correct use of the sonars. Set the average temperature of the area
where the wheel balancer is installed.
7.4.4 - SELF-DIAGNOSTICS
An automatic self-diagnostics cycle is provided for easier trouble shooting. At the end of the self-diagno-
stics cycle, several parameters are displayed which are useful for the Technical Service Department in
order to identify machine faults.

7.4.4.1 - TO CHECK THE ENCODER
When the spindle is rotated:
- the angular position “POS” should vary from 0 to 128;
- the wording “UP” should appear when rotated clockwise and “DOWN” when rotated in the opposite
direction.
Encoder check
tyre
Check for correct
operation of the distance
gauge;
the number increases
when the gauge is pulled
out.
Check for correct ope-
ration of the diameter
gauge; the number
increases when
the gauge is rotated
outwards
Check of the width
sonar: the number
decreases when a
surface is approached
to the sonar
Check of the eccentricity sonar (option):
the number decreases when a surface
is approached to the sonar
In the event of failure or faulty operation of the wheel balancing machine, notify the Technical Service of all
the parameters displayed.
