5.4 Dimensional detections
The dimensions of the balance weights are detected,
on the basis of real data, or rather on measurements
taken directly by the Gauges if the automatic Easy Alu
function is used (Paragraph 5.6). if the data is entered
manually (Paragraph 5.5) these figures are calculated
on the basis of nominal values by adding or subtracting
the average correction values.
5.4.1 Calibration gauge
The internal Calibration Gauge for distance and
diameter is used to enter the distance between the
machine and the left correction plane, as well as the
nominal rim diameter/correction diameter.
The internal Calibration Gauge allows the effective
correction planes and diameters of the adhesive
weights fixed to the bead seats and hidden weights to
be calculated exactly.

and diameter.

– using the distance and diameter measurement
internal Gauge (1, Figure 5-5) the distance
between the machine and the left correction plane
is detected and obtained automatically as well as
the diameter of the rim.
Application:
 Extract and rest the Gauge Head on the rim and
keep it in position until an audible signal is heard.
 Move the Gauge to the idle position.
When the measurements have been completed and
the idle position is reached, the rim dimensions are
shown on the screen in the indicator fields between
the relative arrows. A selection of weight positions (Alu
type) is also shown.
if the Gauge doesn't function correctly or if the
correction positions on the wheel on the machine are
outside the calibration reading field, it is still possible
to set the dimensions from the menu and proceed in
manual mode (Chapter 5.5).
