万用表电阻档的基本误差是以标尺长度的百分数来表示的。在检定时是按水电部 SD 110—83《电测量指示仪表检验规程》规定的两种方法计算误差。然而,用这两种方法进行计算时方法繁琐,而且带来很大的误差。
The basic error of the multimeter resistance scale is expressed as a percentage of the length of the scale. In the test is calculated according to the Ministry of hydropower SD 110-83 “electrical measurement instrumentation inspection procedures” provides two methods to calculate the error. However, the methods used in these two methods are cumbersome and cause a lot of errors.
