测量审核中数字繁用表直流电阻测量结果不确定度评定

The Uncertainty Evaluation in the Resistance Calibtation of the Multimeter in Measurement Audits

测量审核是实验室能力验证活动和认可活动的重要组成部分,该文以测量数字繁用表34401A为例对其直流电阻进行测量,进行不确定度的分析与评定,并对测量审核活动中应该注意的问题及意义加以说明。

Measurement audits is an important part of the laboratory proficiency testing and the laboratory accreditation.Taking the digital multimeter tape of 34401A for an example,measure the function of resistance and give out the evaluation and analyzation of uncertainty in measurement.At last accounting for what we should pay attention to the problem and the significance in measurement audits.
