6.2 UNBALANCE OPTIMIZATION
The symbol is displayed automatically for static unba-
lance exceeding 30 grams (1.1 oz). The program allows
reducing the total unbalance of the wheel by compensating,
when possible, the unbalance of the tyre with that of the rim.
It requires two spins with rotation of the tyre on the rim in the
second spin.
Press + after a fi rst spin and follow the
instructions appearing on the monitor.
7. Setup
The Setup screen provides the user with many possibilities
required for presetting the machine according to his own
requirements. Such settings remain unaltered even when
the machine is switched off.
The following buttons are enabled:
: return to previous window
: return to Measurement screen
from to : for selection of the parameter.
7.1 LANGUAGE
This function allows selecting the language to be used for
displaying descriptive and diagnostic messages regarding
machine operation.
7.2 UNIT OF UNBALANCE MEASUREMENT
It is possible to select whether to display the unbalance
values expressed in grams or ounces.
7.3 UNBALANCE DISPLAY PITCH
This represents the display pitch of the unbalance and varies
according to the unit of measurement selected. The selection
“5 g” (1/4 oz) enables display of the correction values on both
sides such as to bring the static unbalance to 0 (theoretical). It
is recommended to preset this function as standard use of the
machine as it improves the balancing quality. The computer
makes a complex calculation which allows cancelling the
residual static unbalance by varying the value and position of
the counterweights fi xed in steps of 5 grams (1/4 oz).
7.4 UNBALANCE DISPLAY THRESHOLD FOR
TRUCK/CAR
This consists of the unbalance threshold below which the
wording “OK” appears on the screen at the end of the
spin instead of the unbalance; the presettable values vary
according to the unit of measurement selected.
7.5 UNBALANCE DISPLAY PITCH FOR
TRUCK/CAR
This represents the display pitch of the unbalance and
varies according to the unit of measurement selected. The
selection “5 g” (1/4 oz) for cars and of “50 grams” (1.0
oz.) for trucks.enables display of the correction values
on both sides such as to bring the static unbalance to 0
(theoretical). It is recommended to preset this function
as standard use of the machine as it improves the balan-
