6.4 - 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).
6.5 - Spin with guard closed
When “ON” is selected the automatic start of the spin is enabled when the guard is closed.
6.6 - Screen-saver time
When the machine remains unused for longer than the time preset with this function, the processor automatically
returns to the Initial screen. Preset the time in seconds.
6.7 - 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 deceleration 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.
6.8 - 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.
6.9 - To set the clock
Serves for correct setting of the date and time: follow the instructions on the screen.
6.10 - Eccentricity unit of measure
You can select to display the results of the eccentricity measurement in millimetres or inches.
6.11 - First harmonic limit
The fi rst harmonic limit beyond which it is felt suitable to rotate the tyre on the 180° rim. Recommended Limit = 1.2
mm/ 0.05 inch. If a 1st harmonic higher than the set limit is measured, a window appears on screen to indicate the
need to rotate the tyre of the rim.
6.12 - Dynamic + Static
You can select to simultaneously display the dynamic and static unbalance values. In this case, a small window
always appears on the left of the screen displaying the static unbalance with a step of 1 gram / .1 ounce.
