o’clock) is indicated by the central LED coming on for each
phase column.
To return to the normal unbalance indication press any
button.
INFORMATION
The distance between the spokes must be at least 18°
and at most 120° (if not, the errors 24,25 or 26 appear).
Spokes with irregular or inconstant angles can be
compensated.
5.6 UNBALANCE
OPTIMISATION
This operation is performed to reduce the static unba-
lance of the wheel.
It is suitable for static unbalance values in excess of 30
grams.

5.7 OPPOSITE
POSITION
The normal balancing condition requires the correction
weight to be applied at the top (12 o’clock) when the
symbol is displayed:
If OPPOSITE POSITION is enabled, the eventual appli-
cation position for the bottom weight is also indicated
next to the positioning arrows to facilitate cleaning the
rim and the relative application of adhesive weights. The
