Outside correction
Move the wheel manually until all the LED’s correspond-
ing to the side light up. The display shows the measured
unbalance. For unbalance within tolerance 0 (zero); using
values within tolerance can be viewed.
5.3 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 ap-
plied inside 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
To return to the normal unbalance indication press any
button.
INFORMATION
The distance between the spokes must be at least 18°
and at most 120° (if not, the errors 24,25 or 26 appear).
Spokes with irregular or inconstant angles can be
compensated.
5.4 UNBALANCE OPTIMISATION
This operation is performed to reduce the static unba-
lance of the wheel. It is suitable for static unbalance values
in excess of 30 grams.
I a. f no unbalance was measured before, START appears
on the display. Press this button to proceed.
Mak b. e a reference mark on the flange and the rim (using
a piece of chalk, for example).
With the aid of a tyre remover, turn the tyre on the rim
by 180°.
Refi t the wheel in such a way that the reference marks
on the rim and the fl ange coincide.
Press START to begin reading.
RH displ c. ay: percentage reduction value
LH display: actual static unbalance value which can be
reduced by rotation
Ma d. rk the two positions of the rim and tyre, and turn the
tyre on the rim until the positions coincide to achieve
the optimisation shown on the display
