Abstract

The article describes the non-conductive coating thickness simulating system, designed for automatic graduation of the coating thickness gauge using a large number of graduation points. The accuracy of the non-conductive coating thickness simulating system has been evaluated. The procedure for graduation of the coating thickness gauge is described, taking into account the design features and ways to compensate for the main sources of errors of the non-conductive coating thickness simulating system.
