    • The Methods of Distinguishing True from False 3D

      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.
