The following buttons are enabled:

return to previous frame.
7.4 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).
7.5 SPIN WITH GUARD CLOSED
When “ON” is selected the automatic start of the spin is
enabled when the guard is closed.
7.6 SCREEN-SAVER TIME
If this function is enabled, the screensaver will automa-
tically be activated when the machine is not used for a
certain period of time. This function can be disabled by
setting it to 0.
7.7 VISUAL ECCENTRICITY CHECK
At the end of wheel acceleration, as soon as the motor is
disengaged, the guard can be opened for visual control
of any wheel eccentricity as the rotation speed gradually
drops. Do not strike the wheel during the entire decelera-
tion stage; to brake the wheel, close the guard. However,
avoid using the brake as far as possible because this may
compromise unbalance measurements. The unbalance
values measured are only displayed when the wheel has
come to a standstill. This function is active for only one
machine run.
7.8 ACOUSTIC SIGNAL
When “ON” is selected, the sending of an acoustic signal
(beep) is enabled in the following cases:
when any push button is pressed; ▪
when dimensions are acquired in automatic mode; ▪
when the correct angular position for weight application ▪
is reached in the Measurement screen;
when the correct angular position for weight application
▪
is reached in the Position Repeater screen.
7.9 CORRECTION METHOD
One of the three possible correction methods can be selec-
ted based on the specifi c requirements of the customer.
7.9.1 Standard correction method
The wheel balancer considers the unbalance within tole-
rance when the value of each single plane is lower than the
tolerance set.
7.9.2 External plane correction method
If correcting with adhesive weights, the unbalance is considered
within tolerance when the recalculated external plane weight
(clip-on weights) is lower than the tolerance set.
Additional windows appear on the screen always displaying
the residual external plane value (clip-on weight):
7.9.3 I.C. (intelligent correction) correction
method - The option is not enabled for
Canada and the USA
The correction plane unbalance is considered within tole-
rance when both the STATIC and the DYNAMIC TORQUE
unbalances are lower than the tolerance set.
This correction method allows considerably reducing the
weight to be applied, yet maintaining excellent balancing
quality. An icon appears on the screen showing the value of
weight saved with respect to standard balancing.
