Special modes

Selecting the "F" key (1) enables the operator to scroll
the following modes in sequence:
- Split Weight Mode (SWM),
- Minimisation mode.
5.4.1

Split Weight Mode

Selecting is possible only after balancing a HWM wheel
that has an imbalance ≥ 10 gram in the right plane.
Note: The "fine" read-out accuracy is not available
with this mode.
Select this mode to "hide" the right plane weights split
into two parts behind the two spokes that are nearest
to the calculated weight application position. That way,
the weights are not visible from "outside".
Take into account the following limitations (refer to Figure
5.4.1-1):
· The whole enclosed angle is limited to 120°.
· both angles (from "visible weight position" and
"hidden weight position") must be greater than 0°.
· Apply the weight in the left plane of an HWM wheel.
· Don't apply the weight on the right plane but in the
recommended application point.
· Press F(1)+"Spoke" (2) figure 5.4.1-2. S1 appears.
· Turn the wheel until one of the spokes is in the 12
o'clock position, near the application position.
· Press "F" (1 Fig. 5.4.1-2). S2 appears.
· Turn the wheel until the second spoke is in the 12
o'clock position.

· Press "F" (1 Fig. 5.4.1-2). The weight is now split.
The machine can now indicate the two weights and the
relative application points.
5.4.2 Balancing optimisation / Weight
minimisation
Note: even if the optimisation procedure can be carried
out on truck wheels, it is mainly used for car wheels.
General
Optimisation is a refined form of matching.
For optimisation the tyre is mounted relative to the rim
in a position selected according to the results of various
measurements. This normally further reduces any radial
and axial run-out as well as lateral and radial forces,
making the wheel run as silently as possible.
