5.9 - DYNAMIC, STATIC, AND MANUAL ALU MODES
From the measurement screen, press
or
button to select the type required. The 5-LED displays show
the position where to apply the weights. If a spin has already been performed, the processor automatically recalcula-
tes, for each change of mode, the amounts of unbalance according to the new calculation.

This program is designed to improve the quality of
balancing without any mental effort or loss of time by
the operator. In fact by using the normal commercially
available weights, with pitch of 5 in every 5 g, and by
applying the two counterweights which a conventional
wheel balancer rounds to the nearest value, there could
be a residual static unbalance of up to 4 g. The damage of
such approximation is emphasized by the fact that static
unbalance is cause of most of disturbances on the vehicle.
This new function, resident in the machine, automatically
indicates the optimum entity of the weights to be applied
by approximating them in an “intelligent” way according
to their position in order to minimize residual static
unbalance.
