cate that the procedure described in
step 7 must be repeated correctly. If
the angle selected is less than 120°,
the machine immediately displays the
value of weight P2. The LED
remains on to indicate that the "Hidden
Weight" programme is active.

9 Manually turn the wheel, the two
unbalance values calculated are dis-
played in alternation on the display
regarding the outer side as the angular
position of the wheel changes.
10 Apply each of the two balancing
weights as described in the chapter
"ALU 1P, 2P Programmes".
11 Once the Hidden Weights programme
procedure is complete, you may con-
tinue working with any other programme.
The HIDDEN WEIGHT function is combined
with the SHIFT PLANES function to allow
balancing weights which are multiples of 5
grams to be used.
Standard ALU Programmes
(ALU 1, 2, 3, 4, 5)
The standard ALU programmes allow for the
various modes of application of the weights
(Fig. 12) and supply correct unbalance
values maintaining the settings of the rated
geometric alloy wheel data.

If the values of the diameter and of the
distance between the balancing planes,
recalculated on a statistical basis starting
from the rated geometric data of the wheel,
exceed the normally accepted interval
stated in the TECHNICAL DATA section,
the "A Alu" message is displayed.

Some slight residual unbalances may
