摘　　要：不确定度是对模拟式绝缘电阻表的测量过程中的重要因素,在测量评定的过程中,人为引入的读数偏移的不确定度在检测结果中具有重要的作用。如果严重忽略引入的不确定度,引发不确定度偏小的检测结果,如同检测不确定度引发差距的因素是取分辨力引入的不确定度,在目前的大量资料中关于对读数引入的不确定度缺乏研究。另外,绝缘性能的强弱取决于绝缘电阻的质量,因此,对绝缘电阻的测量至关重要。在检测过程中绝缘电阻的质量问题也可以及时发现,避免事故的扩大。Uncertainty is an important factor in the measurement process of an analog insulation resistance meter.In the process of measurement evaluation,the uncertainty caused by the artificial reading offset has an important role in the test result.If the introduced uncertainty is seriously ignored,the detection result with small uncertainty will be caused,as the factor caused by the detection uncertainty is the uncertainty introduced by resolution.In the current large amount of data,Lack of research on certainty.In addition,the strength of the insulation performance depends on the quality of the insulation resistance,so it is important to measure the insulation resistance.Quality problems of insulation resistance can also be found in time during the detection process to avoid the expansion of accidents.
