status of the vehicle body.
Fig.4.10
Operating methods:
According to the prompts on the picture at the bottom of
the interface, measure left, right, front and rear ride
height values respectively, and input them into the
corresponding inputting boxes. Click [NEXT] after
finished.
Caution:
1. Testing conditions for ride height measurement
z
Specified tire pressure
z
Good and even tread pattern
z
Specified wheel bearing clearance
z
Specified rim and tire
z
The brake pedal depressor is installed
z
Counterweight the whole vehicle according to
the normal driving conditions. Adjust the
seats to the middle positions and fill the
gasoline tank full.
2. If the measured values are beyond the tolerance
range, it indicates that the vehicle is faulty, and the
faults must be eliminated before performing the ride
height measurement.
3. For the vehicle with air shock absorbers, please pull
out the security device of the air feeding equipment
to prevent the vehicle from being adjusted up and
down.
4. The sandbags and height measurement meter are
not delivered with the instrument, users should
prepare them by themselves.
Rolling Run-out Compensation
Rolling run-out compensation is mainly used for getting
the inherent parameters of the targets before the normal
measurement, so as to ensure the measurement more
accurate, the interface is as shown in Fig.4.11:
Fig.4.11
Operating Procedures:
1.
Install four wheel clamp targets respectively;
2. Place the transition bridges at the appropriate
positions between the lift and the mechanical
turntables respectively;
3. Turn the front wheels straight ahead, and fasten the
steering wheel with steering wheel holder, and then
remove the brake pedal depressor. Move the
parking wooden chocks back by around 35cm (if
the diameter of the wheel is more than 700mm, the
distance should be increased appropriately) away
to ensure the vehicle can move freely within the
distance scope;
4. According to the system operation prompts, please
push the vehicle back slowly to the position
required, and then pull the vehicle back to the
original location.
Caution:
1.
Before performing Rolling run-out
compensation operation, be sure to fix the
steering wheel according to the requirements,
in order to avoid the wheels' swing to left or
right when performing Rolling run-out
compensation operation, causing the unstable
axis;
2. The line of sight of any camera cannot be
blocked during pulling and pushing vehicle;
3. Keep the force for pushing and pulling the
vehicle evenly, keep the measurement platform
level, and keep the vehicle moving smoothly;
4. Basically keep the target surface vertical to the
ground level, otherwise, too large elevation of
the target in motion will be resulted in, causing
the abnormal target image.
5. Please remove the transition bridges away from
the lift after finishing rolling run-out
compensation measurement.
6. This operation should be performed at the
calibration position.
