5.8.2 Geometric Matching
Open the Matching procedure by pressing key 1 (Fig.
5-101).
The Geometric Matching screen will open (Fig. 5-101).
5.8.2.1 Geometric Matching
At the end of the wheel measuring run the balancer
may prompt carrying out a geometric matching (icon at
the top left of the screen), whose diagnosis can provide
a substantial improvement to the wheel performance.
To start the geometric matching procedure proceed
as follows:
•
Press key 2 on the "Geometric Matching" screen
to start the procedure. The machine prompts to
position the wheel valve at 12 o'clock (Fig. 5-102).
•
Press 3 to confirm the operation.
•
Make a mark on the tyre in the position prompted
by the machine (Fig. 5-103) and press 3 to confirm.
The machine suggests moving the tyre to the tyre
changer in order to align the mark on the tyre with
the wheel valve (Fig. 5-104).
•
After the tyre changer, clamp the wheel on the
balancer and confirm with 3. The machine prompts
to carry out a checking cycle.
•
Lower the wheel guard and if necessary press
START: the balancer will start the checking cycle.
At the end of the checking cycle the control software
will suggest the new value of the weights and their
location on the rim.
During the geometric matching procedure you can
return step by step to the previous screens by pressing
4; pressing 5 displays the balancing screen; press
the ESC or STOP keys to return to the "Geometric
Matching" screen; from this last, press 1b to continue
the previously interrupted geometric matching
procedure.
