ENGLISH
If the buzzer is enabled (see ▪ MENU ), the attainment
of the weight application distance is accompanied by
a beep.
Rotate the gauge until the correction weight adheres to ▪
the
rim
the fact that the weight application position is no longer ▪
vertical is automatically compensated.
- INSIDE CORRECTION POSITION
- OUTSIDE CORRECTION POSITION
To cancel the function, press the button again.
5.4 SPLIT FUNCTION
(unbalance resolution)
The SPLIT function is used to position the adhesive weights
behind the wheel spokes (angle > 18°) so that they are no
longer visible (for alloy rims). Use this function in the ALU
or STATIC mode where the adhesive weight is applied to
the outer side of the rim.
Enter the wheel dimensions in the ALU S mode and press
START.
Turn the wheel to the outer side unbalance correction a.
position.
Mo b. ve one of the spokes to 12 o’clock (e.g.: 1) and
press
Following c. the direction of rotation indicated by the
position LED’s, move spoke 2 to12 o’clock and press
. The value to use for correction in position 2
is displayed.
Mov d. e spoke 1 to the correction position as indicated
by the position LED’s
If the “OPPOSITE POSITION” function is enabled (see the
relative paragraph), the bottom correction position (at 6
o’clock) is indicated by the central LED coming on for each
phase column.
To return to the normal unbalance indication press any
button.
INFORMATION
The spoke-to-spoke distance must be a minimum of 18°
and a maximum of 120° (if not, errors , or
appear). Spokes with irregular or inconstant angles can
be compensated.
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.
