main menu by selecting the
icons.
The following values are displayed for each sen-
sor:
A) transverse goniometer;
B) X axis inclinometer (spirit level);
C) Y axis inclinometer (camber measurement);
D) longitudinal goniometer;
The numbers displayed are the data read by each
individual transducer, on a green or red background
depending on whether or not they are inside the
tolerance range.
The data displayed refer to the transducers' me-
chanical values, data unaffected by compensation
and calibration.
If one or more transducers are on a red background,
try switching the sensor off and back on.
If the new values shown are still on a red background,
calibration cannot be performed. The relative icons
are deactivated but the transducer affected must
be replaced or mechanically repaired (call the
after-sales service).

Calibration Check

To access select the
The values displayed show the variation since the
latest 0 calibration performed.
The goniometers are within the tolerance range
(green colour) if they are inside the range 0° +/-0.10°,
the inclinometers are within the range if they are
inside the range 0° +/-0.20°. If some values are
outside the tolerance range, zero calibration should
be performed.

Zero calibration

To access select the
This program step calibrates only the sensor trans-
ducer zero values.
This procedure must be performed whenever there
are doubts about the aligner's measurements, or
if several cars are found to have crooked steering
wheels after adjustment.
Make sure that the calibrator and sensors are per-

The danger sign warns that if you continue with
the calibration the previous values will be over-
written. Select the
the icon to abort.
The sensor values displayed on the screen are on
a green or red background depending on whether
or not they are inside the tolerance range. The icon
only becomes active, allowing the user to continue
with the procedure, if the values are stable and
within the tolerance range. Select it to save the
calibration values, or press the ESC key to abort
the procedure. The end of the operation and saving
of the new calibration values are shown by figure
.

Calibration log

To access the calibration log, select the icon from
the calibration procedure main screen.
The log contains the date when the data were saved,
the operator and any working notes. The
icon identifies 0 calibration and the
full scale calibration.
If you select an old calibration procedure and press
"Enter", the mechanical values of the sensors will
be displayed in a screen similar to the calibration
screen. An analysis of the variation in the mechanical
values over time can be useful for troubleshooting
any problems on the sensors.
The values are saved at the end of the calibration
procedures. Apart from the operator's details and the
working notes, the system also prompts input of the
serial numbers of the tools used for calibration.

It makes no difference whether the radio aligner
sensors are connected to the central unit by wire
or radio. They are powered by a NiMH battery that
is recharged by placing the head in the housing
