Automatic surface quality tester is the system for online automatic inspection of surface quality of strip steel, the manual inspection is replaced with high-precision camera and computer image algorithm to conduct automatic inspection of surface defects so that it plays an irreplaceable role with high efficiency and sensitivity in production line of high-end plates. During operations, the surface quality inspection of products could be interrupted by system faults and then rhythm of production with galvanizing unit and trace of product quality data in later period could be affected. In the paper, the related effective measures are introduced and analyzed so that the problem of system stability is solved. Furthermore, a set of simple, convenient and rapid judgment method for fault points are summarized, which could be as references for applications of intelligent measuring instrument.
