hub and side pins for tightening it.
THREADED HUB
Threaded part of the shaft on which the ring
nut is engaged to lock the wheel. It is supplied
disassembled from the machine.
LOCKING DEVICE
Wheel clamping device on the wheel balancer
only used for versions with the automatic wheel
clamping system.
ICON
Symbol displayed on the screen illustrating a
button, indicating the graphic representation of
a control.
IPOS Lite
Intelligent Positioning acronym.
SPIN
Procedure starting from the action that causes
the wheel to rotate and the subsequent rota-
tion of the wheel.
OPT
Optimisation abbreviation.
ROD
Acronym of Run Out Detection.
RPA
Acronym of Ricerca Posizione Automatica (Au-
tomatic Position Search).
RUNOUT
Indicates the non-perfect radial and/or lateral
geometry of the wheel.
ULTRASONIC SENSOR
Electronic component that, together with the
information collected by the internal internal
laser detector, allows the wheel width to be
measured and, if present, the wheel runout
detection. This measurement is carried out by
transmitting and receiving ultrasonic waves
trains.
WOBBLE
It is represented by a sinusoidal wave form hav-
ing a specific width, which indicates geometri-
cal deformations in the rotation axis direction.
Wobble (lateral runout first harmonic) may de-
pend on the fact that the tyre or rim is subject to
wear or geometric-mechanical deformations, or
the wheel (or assembly) has not been mounted

correctly on the threaded hub.
UNBALANCE
Uneven distribution of the wheel mass that
generates centrifugal forces during rotation.
