International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), International Organization for Legal Metrology (OIML), International Bureau of Metrology (BIPM), International Union of Pure and Applied Physics (IUPAP), International Union of Pure and Applied Chemistry (IUPC) and the International Federation of Clinical Chemistry (IFCC) 7 international organizations revised the "International Vocabulary of Basic and General Terms in Metrology" (hereinafter referred to as "VIM") in 1993. Our country The Bureau of Quality and Technical Supervision issued JJF1001-1998 "General Metrology Terms and Definitions" (hereinafter referred to as "JJF" National Metrology Technical Specifications. In the above two texts, the accuracy of measurement, the accuracy of flow instruments and the The accuracy levels have precise definitions and explanations. Based on these documents, this article puts forward the issues that must be paid attention to when using these concepts.

Based on this, it can be predicted that in the future, the market's demand for measurement systems and equipment for quality management will continue to grow.

Facing the rapid development of the electronic measuring instrument market in my country, relevant electronic measuring instrument companies will accelerate the pace of technological progress and market development, strive to do a good job in the development of domestic and foreign markets, and truly strengthen and expand China's electronic measuring instrument industry. More, better and newer electronic measuring instrument products are provided to the majority of users.

In recent years, my country's electronic measuring instrument industry has made great progress, and the reliability and stability of the instrument have been greatly improved. Especially in recent years, my country's local instruments have made great progress, especially in the research and development of general electronic measuring equipment and automotive electronic equipment, the gap with foreign advanced products is rapidly narrowing. The development of modularization and virtual technology has brought new development opportunities for my country's test and measurement instrument industry. Together with the increasing attention of the state and governments at all levels, it has provided unprecedented power and opportunities for the electronic measurement instrument industry. To this end, we invite representatives of the industry and the business community to talk about hot topics in the domestic instrument field and exchange successful experience of enterprises, hoping to play a certain role in the development of my country's electronic measuring instrument industry.

All markets are uneasy in the aftermath of the crisis for stability, but the electronic measuring instrument market represented by oscilloscopes has such a voice: the electronic measuring instrument market will usher in another spring.

The electronic measuring instrument industry has been highly valued by the country since the founding of New China. During the "First Five-Year Plan" and the "Second Five-Year Plan", electronic measuring instruments accounted for 12 of the 156 major national projects built at that time, accounting for 7.7% of the total national major projects. By the end of the second five-year plan, 11 factories and 1 research institute with the international advanced level at the time were basically completed, laying a preliminary foundation for the development of my country's electronic measuring instrument industry.

The electronic measuring instrument industry is a basic equipment industry and the foundation of the entire electronics industry. It supports the development and progress of most industries on a very small scale, such as semiconductors, computers, digital televisions, modern communications, aerospace, etc. The participation and support of measuring instruments is unimaginable. There is no doubt that electronic measuring instruments occupies an extremely important position in various industries of the national economy.

Electronic measuring instruments are roughly classified into the following categories according to their working principles and uses. To
