Instrument calibration is an operation performed to determine the value of a measuring instrument and the national standard value under certain conditions (such as temperature, humidity, noise, etc.). The result of instrument calibration is to express or measure the measured value of the instrument and give the correction value of the relevant parameters; in order to determine whether the value of the measuring instrument is accurate, these results will generally appear in the instrument calibration report for use by manufacturing enterprise users. Measuring instrument calibration plays an important role in the product quality of all walks of life and the quality of accurate production instruments. If there are a large number of wrong production instruments, it is easy to damage the production of products, and there are many unqualified products, which will bring immeasurable losses to the enterprise. Instrument calibration ensures the continuous and effective operation of the quality system and is also a way for enterprises to save energy and reduce consumption. Enterprise system management can save a lot of costs, such as the loss of raw materials, the consumption of personnel, and the utilization rate of time will be greatly improved. Including ISO system certification, enterprise audits, customer factory inspections, etc. for the calibration of enterprise instruments.

After the instrument is calibrated, the manufacturer should determine whether the production instrument can continue to be used. If the measuring instrument does not meet the needs of continued use, the measuring instrument needs to be repaired or discontinued. Do not cause quality problems in all aspects of the product due to instrument errors. Instrument calibration reports, calibration agency labels, etc. can be used as supporting materials in external requirements audits to meet the management system's requirements for instrument calibration. Enterprises that do not perform instrument calibration are prone to product quality problems, leading to greater economic losses. 1. Under the guidance of the Scientific Outlook on Development, establish a metrology risk management system. 2. Establish a long-term mechanism for daily monitoring of metrology risk information. 3. Establish a metrology risk analysis report, early warning and release system; conscientiously organize and carry out metrology risk investigations. Conduct special research on key issues found in daily risk monitoring. Conduct in-depth research on statistical methods for risk monitoring data of different metrology instruments. Use reform and innovation as the driving force to improve the metrology risk management system, extend it vertically and horizontally, improve the metrology risk monitoring system, refine the risk monitoring process, and conduct scientific research on risk measurement soft topics. In short, risk monitoring information comes from the grassroots. Accurate and reliable risk monitoring and analysis, on the one hand, help promote scientific decision-making and provide direct guidance for joint work in the management field; on the other hand, serve the grassroots. It requires the joint efforts of quantitative management and technical departments and institutions at all levels to be practical and ultimately establish a scientific and effective forward-looking and guiding metrology risk prevention and supervision system to make metrology supervision more scientific, targeted, timely and effective.
