The basic concepts of measuring instruments include: accuracy, error, measuring standard equipment, length measurement, angle measurement, shape measurement, traditional optical instruments. Application in precision measurement and so on.

There are two kinds of contact tests for measuring instruments: contact test and optical test: general measuring tools and 3D measuring tools (CMM is also called cubic element) and three-dimensional CMM is also called cubic element. It can measure many complex spatial dimensions, such as dies and automotive products.
