Manual Wheel Parameter Entry - Corghi ProLine 650 Manuel D'utilisation

Take great care to position the arm correctly
so as to ensure accurate data reading.
- Keep the arms in contact with the rim
until the machine has acquired the va-
lues. The geometric data are displayed
in sequence:
• d distance value;
• di diameter value;
• Lr width value.
When a geometric value is displayed, the
corresponding LED illuminates on the
display panel.
- Check the values measured and then
return the arm to the rest position.
- If an incorrect value has been acquired
during the measurement phase, move
the arms to the rest position and then
repeat the operation.
Measurements can also be taken by moving
one measuring arm at a time. In this case,
sensors can be used with no preset order.
Pay maximum attention to the measured
data since they are influenced by the
stored ones.
After setting geometric dimensions cor-
rectly and returning the sensors to the
rest position, the unbalance values recal-
culated according to the new dimensions
are displayed.
IMPORTANT
bear in mind that the wheel's nominal
diameter (e.g. 14") refers to the planes
on which the tyre bead rests, which are

obviously inside the rim. The values mea-
sured are with reference to external planes
and, as a result, are
smaller than the nominal values due to
the thickness of the rim itself. The correc-
tion value therefore refers to an average
thickness of the rim. This means that the
data measured on wheels with different
thicknesses may vary slightly (2 or 3 tenths
of an inch maximum) from the rated values.
This is not a lack of accuracy of the measu-
ring devices, but reflects reality.

If the automatic measuring arm fails to ope-
rate, the geometrical data can be entered
in manual mode by following the procedure
indicated in the paragraph "Manual wheel
