through the camera with high resolution, it is
necessary to keep X-831M wheel aligner away
from the outside infrared rays (e.g. sun-lights) from
directly lighting to the targets and reflecting to the
cameras. It is also necessary to avoid blocking the
light way from the targets to the cameras for a long
time during the instrument is working.
 The targets of X-831M wheel aligner are the key
components for testing. Do not damage their
structures when using and storing. Keep the
surface of target clean. Please use the soft cloth
dipped with an appropriate amount of the neutral
detergent or the absolute alcohol to wipe the
surface of target lightly if there are some smuts on
it.
 When using and storing, please pay much
attention to prevent water from entering into the
targets.
 The wires inside the post and the lateral beam are
connected compactly. Don’t move them after first
installation.
 The precision position calibration has been
performed for the cameras after first installation,
the user can not move or wobble the post or lateral
beam during or after using it.
 Without approval of the supplier, please do not
disassemble the post and the lateral beam in order
to avoid damaging the components, influencing the
test accuracy and increasing the costs and
difficulties of maintenance and repair. For the
damage caused by unauthorized disassembling
will not be covered by the Warranty.
 The fastening method should be selected correctly
and flexibly according to the actual conditions of
the rim, the turning force should be equal when
fastening, after fastening, please check the wheel
clamp again.
 The force should be equal when using each knob,
please don’t fasten it too tight in order to avoid
damaging the locking mechanism or other parts.
 After using, please cut off all power supply timely.
 The cameras of X-831M wheel aligner are the key
optical components for testing. Do not impact them
when using, keep the surface of the camera lens
clean. Please use the lens paper to wipe the
surface of the camera lens lightly if there are some
smuts on it.

Fig.5.1.
Fig 5.1
1. Confirm the lift height
The present working height of the lift is of the height
between ground and turntable upper end surface
center.
2. Confirm the post installation center line
Obtain two center points by measuring front and
rear widths between two lift runway rails. Connect
these two points to confirm the center line of the lift,
lengthen the line in the direction of post.
3. Confirm the post base line B
Confirm line B according to the positions of two
turntables. Make sure that this base line is parallel
to turntable center line and vertical to lift center line.
The distance between line B and the turntable
center line is 1900～2800mm.

Note:
It is not necessary to perform the calibrating operation
during equipment first installation. Generally speaking,
only in following two cases is the calibrating operation
performed:
1. The camera is adjusted or moved;
2. The target is changed.
Please do not perform the calibrating operation in
normal test operation process.
Target Calibration
After the camera recalibration, it is required to perform the
target calibration operation, in order to reduce the errors
caused by the target itself, and the system will automatically
create the corresponding calibration files and save them.
The target calibration procedures are as follows:
Turn the steering wheel to keep the front wheels straight
forward, and then hold the steering wheel with the steering
wheel holder. Remove the brake pedal depressor, and then
put up the vehicle body with the lift, keep the wheels hanged
in the air and can be turned freely.
Install the four wheel clamps and targets respectively, and
then adjust each target be inclined forward 10 degrees
around.
Select [System Management]-[Target Calibration] in the
main interface, after entering correct password, please click
“Start TID calibration” button to start calibration, as shown in
Fig.5.18.

Cautions
1. Avoid the targets be blocked during calibration as
far as possible.
2. Please pay attention to the target calibration
sequence (FL, FR, RR and RL).
3. If target is turned forward, the turn angle is of
negative angle; if turned backward, positive angle;
before starting calibration, the default position of target
is of 0 degree. As far as possible, keep the target be
inclined forward 10 degrees around.
