Operation
In addition, the correction weights needed for balancing
can alsobe reduced.
If optimisation is not required, weight minimisation (also
known as matching) is possible.
For example, when the rim has no shape defects,
meaning that wheel imbalance depends exclusively on
tyre irregularities. In such cases, the rim imbalance
may be positioned relative to the tyre imbalance so
that they compensate one another and the machine
calculates a minimum correction weight.
Instructions for balancing
optimisation / weight minimisation
1 2 During tyre changing operations required for balancing
optimisation / weight minimisation, the wheel balancer
can be used as a conventional wheel balancer by
another operator.
For this purpose, interrupt the optimisation /
minimisation program by pressing the STOP key (3).
The electronic unit will store the current program step,
the rim dimensions and all measurements taken so
far.
To continue with the optimisation / minimisation
program, press the F key (1). The program then
continues from the step where it was interrupted, with
the relative measurement values and the balancing
optimisation / weight minimisation may continue.
If a measuring run is interrupted by operation of the
STOP key (e.g.: to clamp the wheel better or due to an
emergency), the machine returns to the previous
program step. Reset the valve position and continue
balancing optimisation / weight minimisation.
After interruption by operation of the STOP key the
readings refer to the imbalance of the latest measuring
run.
To restart balancing optimisation / weight minimisation
after an interruption, simply press the PRO-MATCH key
(2).
Wheel clamping means compensation is cancelled by
starting the balancing optimisation / weight

minimisation cycle.
Balancing optimisation program cycle
The following is a description of the balancing
optimisation program cycle (code OP) and weight
minimisation (code UN).
Balancing optimisation
If after the measuring run the imbalance in the left or
right correction plane and/or the static imbalance is
more than 30 grams, perform optimisation immediately
after the measuring run. Activate the function by
pressing the "F" key (1) then the PRO-MATCH (2) key.
