Chapter III Operation
Measure Menu
When the Measure icon is selected from the toolbar
on any readings screen, a screen appears that allows
the operator to measure any wheel alignment angle.
The icons on this screen are explained below:
•
Caster Swing
– measures the Caster/SAI and TOOT
angles on the turnplates.
•
Steering Level Check
- Selecting this feature allows
the user to check the level of the steering wheel.
•
Single Wheel Compensation
– instead of the normal
compensation sequence, the vehicle can be jacked
to allow each wheel to be positioned independently.
This is useful if a wheel must be removed during the
alignment, for example to install a shim in the rear.
•
Vehicle Dimensions (Advanced Option)
– Provides
additional information about the condition of the ve-
hicle’s frame, such as setback and axle offset.
•
SAI Only Elevated -
Steering Axis Inclination can be
measured for diagnosis of certain steering component
problems while the front of the vehicle is elevated.
•
Max Turns
- Is selected to measure the amount of
steering angle to the right and to the left. These are
generally symmetrical and this test can help determine
if a steering linkage is damaged.
•
Toe Curve Change
– measure the individual wheel
toe change as the suspension goes through jounce
and rebound.
•
Camber at 0 Toe
- This process is recommended
by some vehicle manufacturers, such as Mercedes
Benz. It measures the camber of each front wheel
separately with the wheels straight ahead (zero
toe).
