A calibration system is a kind of technical document formulated for the purpose of measuring and transferring values. Its purpose is to ensure that the measurement point is measured accurately and the measurement state is not excessive, and the measurement value can be accurately transferred to the measurement instrument. The components of the calibration system include:
The relationship between the measurement instruments and the value transfer from the calibration instrument selected by the certifier to the calibration instrument: the methods and measuring instruments allowed (or recommended) to be used; the uncertainty requirements of the standard instrument to reproduce or preserve the value ; …The metrology-related standards and measurement bases shall be approved by the State Council Metrology Safety Administration and the market shall organize the comprehensive creation and promotion of the system table, and the system table shall meet the requirements of accuracy and capability. In the calibration work, the system table can be used as a reference to determine the appropriate system table. The system table shall be compiled in accordance with the provisions of laws and regulations, and the relationship between the domain and the transmission of information shall be clear. The domestic and foreign cards shall be signed and used, and the verification shall be carried out with sincerity to ensure that the system is suitable for the people and practical.

JJF 1104—2IL3
When the calibration system is used, it is necessary to determine the working principle of the calibration system according to the measured value, measurement range and working principle. The system calibration system is composed of the measuring system and working principle, and the appropriate value is determined. The accuracy of the calibration system is reduced from the standard to the standard. The accuracy ratio of two adjacent equal-valued instruments is different in the range of 2. Therefore, the accuracy of the calibration system is relatively large. The difference between the maximum allowable error and the measured value will be different. In actual use, the uncertainty ratio between two adjacent levels should be selected according to the above situation. It can be determined according to the specification and possibility. The larger value can be selected as much as possible. 6.8 The uncertainty of the measurement result cannot be compared with the maximum allowable error of the standard. The uncertainty of the measurement result cannot be compared with the maximum allowable error of the standard. The uncertainty of the measurement result cannot be compared with the maximum allowable error of the standard. tt||, note that the displayed value is not certain, the joint creation of the year 2 of the request for the actual forget degree 5,
