Possible types of correction:
Balancing of steel or light alloy rims with application of clip-on
weights on the rim edges
The STATIC mode is necessary for motorcycle wheels or when it is
not possible to place the counterweights on both sides of the rim.
Balancing of light alloy rims with application of adhesive weights on
the rim shoulders.
Combined balancing: adhesive weight on the outside, clip-on weight
inside.
Combined balancing: clip-on weight outside and adhesive
weight inside.
Balancing of alloy rims with hidden application of the adhesive
weight on the outside.
Combined balancing: clip-on weight inside and adhesive hidden
weight outside (Mercedes).
5.5.5 - Automatic minimization of static unbalance ►
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.
