7.3 - Minimization of static unbalance

- When using the normal commercially available weights, with pitch of 5 in every 5 g, 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 the disturbances on the vehicle. The computer automatically

indicates the optimum entity of the

weights to be applied by approximating them in an “intelligent” way according to their position. (Pitch 5 grams/0.25

ounce for cars, 50 grams/1 ounce for trucks).

- Press

to display the actual unbalance (Pitch 1 gram/0.1 ounce).

- The instruments indicate

“0” for unbalance less than 5 grams/=.4 for cars and 50 grams/2 ounces for trucks; to

display the residual unbalance press

7.4 - Indication of counterweight position in alu-s

After calibrating the machine in ALU-S mode, proceed as follows to cancel approximations made in mounting the

counterweights:

- Press

the following appears:

DISTANCE NOT DEFINED

- Extract the distance gauge.

- The reaching of the correction application position for the unbalance correction weights is indicated by the

unbalance display on the relative plane (see fig. 15)
