FLUKE 5730A是当前电学实验室常用的等级最高的多功能源，用何种设备，采用什么方法对它进行传递校准是一个普遍的技术难题，选好了设备，实际校准过程中又该注意哪些细节，才能保证校准数据的可靠准确呢? 经过大量深入的研究，考察了不同标准器的技术性能和应用特点，对5730A的各项主要功能、每个量程下计量部门常用的校准关键点逐一进行了TUR（测量不确定度比率）的计算，从而确定了适当的校准标准和校准方法，也符合国内JJF 1638-2017多功能标准源校准规范的通用要求。广大计量人员可以参考和应用文章中介绍的方法，建立相应的标准装置，并开展校准工作。
FLUKE 5730A is the most commonly used multi-functional source in the current electrical laboratory. Which equipment and method are used to transfer traceability and calibrate FLUKE 5730A? It is a common technical issue to select the proper equipment and what details should be paid attention to in the actual calibration process in order to ensure the reliability and accuracy of calibration data. After a lot of in-depth research on the technology of different standard devices, calculating the TUR (measurement uncertainty ratio) of key test points commonly used by metrology departments in each range of main functions of 5730A one by one, then the appropriate calibration standards and methods are determined, which also meet the general requirements of JJF 1638-2017 multi-functional source calibration standard. Many metrology engineers can refer to and apply the methods described in the article, establishing corresponding standard devices, and carrying out their calibration work.
