5.4.4 - ALU AND STATIC MODESFrom the Measurement screen, press button to select the type required. The 5-LED displays showthe position where to apply the weights. If a spin has already been performed, the processor automaticallyrecalculates, for each change of mode, the amounts of unbalance according to the new calculation.Fig. 19DYNAMICBalancing steel or light alloy wheel rims byapplying clamp weights on the edge of the wheel rim.STATICOALU - SThe static mode is necessary for motorcycle wheels orwhen it is not possible to place the counterweights onboth sides of the rim.Balancing of light alloy rims with application of adhesiveweights in positions inside the rim (user settable).ALU - 1Balancing of light alloy rims with application of adhesiveweights on the rim shoulders.12/13 mmresting surfaceALU - 2Balancing of light alloy rims with hidden application of theouter adhesive weight.

The damage of such approximation is emphasized by the fact that static unbalance iscause of most of disturbances on the vehicle. This new function, resident in the machine, automatically indicates theoptimum entity of the weights to be applied by approximating them in an “intelligent” way according to their positionin order to minimize residual static unbalance.gdxChoice with minimumstatic residualgsxgdxgI 0226 GB - 19
