The monitor shows a window displaying the imbalance values of the wheel as it is
mounted on the balancing machine; when the wheel is brought into the position
indicated by the yellow arrow, the current imbalance values are replaced by the
imbalance values and the percentage improvement which can be obtained by
shifting the tyre on the rim again. If no improvements are possible, the machine
still displays the weights calculated with tyre shift; however, the percentage
improvement indicator will have a minus sign and the top of the window will be red
(instead of green).
If the improvement is considered insufficient or it is not possible to reduce the
imbalances, the user can select the
balance the wheel; otherwise, the system moves on to the fourth and final phase of

the monitor.

will indicate this error with the "Err 6" message. This means that the entire
procedure should be repeated from the beginning. The error message will
