Pro-Match/Weight minimisation

12. Pro-Match/Weight minimisation
12.1 General
Pro-Match, the optimisation program, is an improvement of the
matching procedure.
Tire and rim are adjusted on the basis of unbalance test
results. This produces reduction of lateral and radial run-out
and of radial and lateral force variation, as well as reduction of
balance weight size.
If Pro-Match is not desired, it is possible to achieve weight
minimisation.
This is possible when there is no deformation of the rim, but
where unsmooth ride is only due to non-uniform mass distri-
bution in the tire. In this case the unbalance present in the rim
can be adjusted relative to the unbalance present in the tire so
that the unbalances compensate for each other and the small-
est possible balance weight can be determined.

12.2 General instructions for the Pro-Match/

weight minimisation programs

It may be necessary to interrupt the Pro-Match/minimisation
program by pressing the STOP key. The electronic unit will
store the current program step, the rim dimensions and all
measurements taken so far.
To continue with the Pro-Match/minimisation program, press
the OP and CODE keys in succession. The program then
continues at the step where it was interrupted, using the initial
data inputs and measured data.
If a measuring run is interrupted by operation of the STOP key
the machine will switch back to the previous program step.
Pro-Match/minimisation is then continued by entering the valve
position of the wheel with the PRO MATCH key.
After interruption by operation of the STOP key the readings
refer to the unbalance of the latest measuring run.
To start the Pro-Match/minimisation program anew after an
interruption, it is only necessary to press the PRO MATCH
key.
During Pro-Match/minimisation a measuring run always has to
be started with the START key.
