The system can determine the distance of the relevant zone on the
wheel's surface. As a result, there is a full three-dimensional set
of coordinates of the wheel/tyre surface.
Using the multitude of those points, as well the wheel center and
the angle of the wheel to the vertical (moreorless producing the
camber value later on), and the horizontal angle are continuously
being measured. The latter one is one of the bases for toe
calculation.
Indisposable prerequisite for measurement is, that the camera
can clearly ‚see' the coloured stripes. This could eventually be
disturbed by direct or reflected daylight. In such a case, the retrofit
kit Light Protection (1 987 009 G61N) is verry helpful.
The limit for tolerable ambient light is around 450 Lux, measured
on the rim, with the Luxmeter's probe looking horizontal. In any
case, the system will inform clearly about a light problem, and
typically, you can directly continue in the process, by making
some shade on the wheel zone that is indicated in the message
box.

It is recommended not to touch the probe during a measurement
process. For sure, you should not abuse the probes as additional
shelf space.
Slight oscillation of the probe in transversal direction can not be
stopped completely from a mechanical standpoint. On the other
hand, it is not a problem, as there are inclinometers in the main
body, that do exactly measure this oscillation, and that are used
to offset for any deviation.
Actuation of the probes and the communication about status and
measured values from the probes to the central PC takes place
via radio (WLAN).
The metrology is specified to be able to measure all kinds and
sizes of tyres/rims. Operating range: The outside diameter of the
tyre (the rim diameter is not important here) has to be within a
range of 450mm and 750mm. Everything ranging from steel rims,
black, rusty, across all kinds of aluminum rims, to shiny chrome
rims can be measured. Of course also with low profile tyres.
This gives you an excellent coverage of measurable wheels.
Measurement is not only without touching the wheel, but this is
also the first working and available workshop aligner in the world,
that does not require any kind of preparation on the car, as would
be the mounting of wheel clamps or targets. In the case of steel
rims, you can even leave wheel caps in place.
As some sort of fallback position in case of a loss of radio
communication, there is also a cable connection from the main
body to the probe. With this, it is possible to find out independent-
ly whether the probe's PC is turned on. Also, this enables the
central system to reset or restart the probe PC in case of need.
The probes come with a set of ‚Emergency Keys', two USB
memory sticks that hold a backup of the original contents of the
probe's memory. With these sticks, the probes can be completely
recovered including their internal calibration, in case that some
files on the flashcard were damaged e.g. due to a power loss
during memory access.
