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 the Pro-Match recommended after a measuring run if
the unbalance in left and/or right correction planes and/or static
unbalance is greater than 1 ounce (e. g.
Fig. 114 ).
D
Demount the tire and clamp the rim.
D
Depress the PRO MATCH key (Fig. 115, item 1) .
Reading OP.1 (Fig. 116) 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.
D
Rotate the tire so that the valve stem is set at
12:00 o’clock.
D
Depress the PRO MATCH key (Fig. 115, item 1) to enter
the valve position.
Reading OP.2 (Fig. 117) comes up.
An incorrect valve position input can be corrected by repeating
this step.
Weight minimisation (matching)
If no Pro-Match, but only weight minimisation (i.e. without com-
pensation with the rim only) is desired, proceed as follows:
D
Clamp the tire/rim assembly.
D
Depress the PRO MATCH key (Fig. 115, item 1) .
Reading OP.1 - Fig. 116 comes up.
D
Depress the FINE key (Fig. 115, item 2) to switch over to
the minimisation program.
The reading goes to Un.3 (see § 12.4, Fig. 127) where you pro-
ceed with the program.
D
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. 128)
where you continue.
The valve position input of OP.1 remains entered.
