Fast Selection Program acronym
LOCKING DEVICE
Wheel clamping device on the wheel balancer only used for versions with the automatic
wheel clamping system.
OPT
Optimisation abbreviation.
SELF-CALIBRATION
This procedure calculates suitable correction coefficients starting from known operating
conditions. It improves the machine accuracy by correcting to a certain extent the calculation
errors that may result from the alteration of the machine's features over the course of time.
SENSOR (measuring arm)
Mobile mechanical element that, when brought into contact with the rim in a specific position,
measures the geometric data: distance, diameter. Data can be measured automatically if the
sensor is equipped with suitable measurement transducers.
SPIN
Procedure starting from the action that causes the wheel to rotate and the subsequent rota-
tion of the wheel.
STATIC BALANCING
Procedure for correcting only the static element of the unbalance, by applying only one weight,
usually at the centre of the rim well. Accuracy increases as the width of the wheel decreases.
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.
UNBALANCE
Uneven distribution of the wheel mass that generates centrifugal forces during rotation.
