一、Rolling Compensation       

       Real: Rolling compensation is a must.

       Fake: Static measurement or fake rolling compensation.

       Analysis: Static measurement or fake rolling compensation cannot compensate the data of deformed of steer ring, wheel clamp and target axis.

二、Camera Beam

       Real: No need for level camera beam.

       Fake: The installation of the camera beam depends on the horizontal bubble ruler and level camera beam is a must.

三、Wheel Adaptor

       Real:The head of adaptor does not need to closely contact with the rim  as long as the adaptor is not loose and does not fall off.

       Fake: The adaptors have to closely contact with the rims, otherwise the measurement accuracy will be affected.

四、Lift Platform

       Real: Horizontal lift runways cast little influence on accuracy. Hence even 20-50mm horizontal difference is acceptable.

       Fake: The two runways have to be on the same horizontal line, otherwise they will severly affect camber measurement.

五、Camera Replacement

       Real: Once the camera is damaged, replacing the broken one and performing on-site calibration will solve the problem.

       Fake: Once a camera is broken, the whole camera beam is required to be sent back to the factory for replacement and calibration.  

       Analysis: Fake 3D needs platform like CCD to make calibration, which normal users usually lack.
