Abstract
In order to investigate the reliability of verification results of DC resistance tester, the uncertainty of verification results was evaluated. According to JJF 1059.1-2012 “evaluation and expression of uncertainty in measurement”, a mathematical model is established to analyze the sources of uncertainty of measurement results and calculate the components of uncertainty. Taking 500m$\Omega$ point of DC resistance tester as a verification point, the standard uncertainty expressed by absolute value and relative value is 321$\mu\Omega$ and 0.064% respectively. Finally, based on the calculation of uncertainty, the conformity evaluation method and process of the tested instrument are given.
为了研究直流电阻测试仪检定结果的可靠性,对检定结果的不确定度进行了评定。根据JJF 1059.1-2012《测量不确定度的评定与表达》,建立数学模型,分析测量结果的不确定度来源,计算不确定度分量。以直流电阻测试仪500m $\Omega$点为验证点,用绝对值和相对值表示的标准不确定度分别为321 $\mu\Omega$和0.064% respectively. Finally, based on the calculation of uncertainty, the conformity evaluation method and process of the tested instrument are given.
