Abstract： Metrology inspection is the basic work of instrument equipment quality inspection， and plays an important role in ensuring the application quality of instrumentation. In the process of measurement and inspection， it is required to have a complete measuring instrument to ensure the integrity， so as to ensure the stability of the application of the instrument and the indication value is accurate. In this regard， this paper first introduces the content of electronic and electrical products measurement and inspection work， and then conducts detailed research on the maintenance points of electronic and electrical products measurement and inspection instruments and future development trends， in order to promote the technical level of measurement and inspection instrument for electronic and electrical products， and make full use of its application advantages.

Keywords： measurement instrumentation; maintenance; development

With the rapid development of science and technology， the accuracy requirements for electronic and electrical products are getting higher and higher. At the same time， the types of measurement and inspection instruments are gradually increasing. Only by maintaining the instruments can the accuracy of measurement and inspection be guaranteed. By applying the electronic and electrical product measurement and inspection instruments to the actual production of the enterprise， it is possible to monitor and manage the operating parameters of the equipment and production lines. It can be seen that the accuracy of the measuring instruments and equipment will directly affect the production efficiency of the enterprise， and the maintenance of the measuring instruments must be strengthened and promote the development of measuring instruments by applying advanced technology.

I. Electronic and Electrical Products Measurement and Inspection Work Content

Nowadays， with the improvement of the productivity level of enterprises and the improvement of product quality requirements， the selection of advanced and accurate measurement and inspection equipment has become an important direction of enterprise modernization development [1]. However， the types of measuring instruments and the accuracy of measurement control in China still need to be developed. Compared with developed countries in the west， there is a big gap. In practical applications， problems such as success rate is too low and poor operation stability often occur. The development of domestic equipment production technology has a negative impact. Therefore， it is necessary to increase the development of electronic and electrical measurement instruments. In the measurement and inspection work， scientific detection method should be provided first and equipped with complete testing equipment. Nowadays， in the production of various industries and people"s daily lives， the measurement and testing work has become popular， through the application of metrological inspection instruments， it can detect， record， analyze and control the quality and quantity of materials. It can not only transmit the standard quantity， but also detect， supervise and control the production process and production process of the material to ensure product quality.
