Pro-Match/Weight minimisation
12.3 Pro-Match program
The sequence of operations for the Pro-Match program and
for the minimisation program (code Un) is described below,
with the possible readings illustrated in the figures.
Pro-Match
Use of Pro-Match is recommended automatically after a mea-
suring run by viewing the OP symbol if the unbalance in left
and/or right correction planes and/or static unbalance is greater
than 1 ounce
(Fig. 109)
.
•
Demount the tire and clamp the rim.
•
Depress the PRO MATCH key
(Fig. 110, item 1)
.
Reading OP.1
(Fig. 111)
comes up.
Note that after all readings in which the valve symbol is shown
at the rim contour the PRO MATCH key must be pressed to
enter the valve position (with the tire valve positioned at 12:00
o’clock) after the tire has been displaced on the rim.
•
Rotate the tire so that the valve stem is set at
12:00 o’clock.
•
Depress the PRO MATCH key
(Fig. 110, item 1)
to
enter the valve position.
Reading OP.2
(Fig. 112)
comes up.
An incorrect valve position input can be corrected by repeating
this step.
Weight minimisation
If no Pro-Match, but only weight minimisation (i.e. without
compensation with the rim only) is desired, proceed as fol-
lows:
•
Clamp the tire/rim assembly.
•
Depress the PRO MATCH key
(Fig. 110, item 1)
.
Reading OP.1 -
Fig. 111
comes up.
•
Depress the FINE key
(Fig. 110, item 2)
to switch over
to the minimisation program.
The reading goes to Un.3 (see § 12.4, Fig. 122) where you
proceed with the program.
•
At level OP.2 the compensation run can still be omitted.
Again, proceed with the program by depressing the
FINE key.
As a result the reading goes to Un.4 (see § 12.4, Fig. 123)
where you continue.
The valve position input of OP.1 remains entered.
