以MF500为例的一种模拟式万用表测量值不确定度评定方法

Take MF500 as an Example of the Measurement Uncertainty Assessment of the Analog Multimeter

模拟式万用表是部队日常装备保养、维修中不可缺少的一种检测工具,它具有造价低廉、便于携带、易用耐用等等优秀特点。正由于这些优点海军各级计量保障机构大多建立相应的测量标准以保证保障范围内模拟式万用表的受检率和完好率,因此提高模拟式万用表检定方法、研究模拟式万用表的测量不确定度评定方法对于提高各军事计量技术机构计量检定水平和计量管理水平具有重要意义。本文以部队日常使用频率较高的通用型模拟式万用表MF500为例提出了一种简单明了、易于操作的模拟式万用表测量不确定度评定方法。

The analog multimeter is an indispensable testing tool in the daily maintenance and maintenance of military equipment. Is because most of these advantages navy metrological guarantee agencies at all levels to establish the corresponding measures to ensure security within the scope of the analogue multimeter of rate and tested pipe,thus improve the analogue multimeter calibration methods,the research of analogue multimeter measurement uncertainty evaluation method to improve the level of military metrology technology institutions metrological verification and measurement management level is of great significance. Taking MF500 general analog multimeter with high frequency in daily use as an example,this paper proposes a simple and easy to operate method to evaluate the uncertainty of measurement of analog multimeter.
