Operator’s manual
For models with automatic inner (distance and diameter) sensor
and automatic and outer mechanical (width) measuring sensors
To enter the distance, diameter and width
values automatically, proceed as follows:
- bring the automatic internal measuring
arm (A, Fig. 8) into contact with the inner
side of the rim as shown in Fig. 11 and at
the same time bring the automatic external
measuring arm (B, Fig. 8) into contact with
the outer side Fig. 12a.
- 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 values.
When a geometric value is aquired, the
corresponding LED illuminates on the
display panel.
- 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 be taken also 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 correctly and returning the sensors to the rest posi-
tion, the unbalance values recalculated according to the new dimensions are displayed.
IMPORTANT
bear in mind that the wheel's rated diameter (e.g. 14”) refers to the planes on which
the tyre beads rest, which are obviously inside the rim. The values measured 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 correction value therefore refers to an average
thickness of the rim. This means that the data measured on wheels with different thick-
nesses may vary slightly (2 or 3 tenths of an inch maximum) from the rated values. This
is not a lack of accuracy of the measuring devices, but reflects reality.
If the automatic measuring arm fails to operate, the geometrical data can be entered in
manual mode by following the procedure indicated in the paragraph "entering wheel
dimensions - for models with manual inner sensors (distance and diameter)".
If the inner sensor (diameter and distance) fails to operate or
with the inner manual sensor
- Use the keypad to enter the wheel geometric data by following the procedure described
below:
