Corrective Weight Placement
After the wheel spins and out of balances are mea-
sured and displayed, the corrective weight amount
appears on the weight display window for Inboard and
Outboard weight locations. Bars appear on either side
of the wheel cross-section diagram to aid in positioning
the wheel for corrective weight at the application point.
After a measurement cycle, rotate wheel until the
center weight position bar blinks, indicating the cor-
rect weight placement position is at top-dead-center.
If the out-of-balance is less than the chosen threshold
value, 000 appears instead of an out-of-balance value
to indicate that, on that particular side, the wheel is in
tolerance.
