众所周知,使用数字电压表具有测量自动化、操作简便、测量速度快、数据直观等优点。随着数字电压表的迅速发展,特别是准确度,灵敏度和可靠性的提高,使得数字电压表用于高精度的测量成为现实。本文以实践为基础总结介绍用数字电压表检定标准电阻的方法和结果比对及误差分析等。一、检定方法根据标准电阻检定规程中规定,在具备Ⅱ等标准电阻的前提下,可以开展对0.01级标准
As we all know, the use of digital voltmeter with measurement automation, easy to operate, fast measurement, data intuitive advantages. With the rapid development of digital voltmeter, especially the improvement of the accuracy, the sensitivity and the reliability, making the digital voltmeter used for high-precision measurement becomes a reality. This paper summarizes the practice based on the use of digital voltmeter standard method of verification and comparison of results and error analysis. First, the test method According to the provisions of the standard resistance test procedures, with the standard resistance such as Ⅱ premise, you can carry out on the 0.01 level standard
