欧姆表(指磁电系,如万用表的欧姆档)与中学中使用的其它电表相比有一个不同之处是;欧姆表的刻度标尺是非线性的,因而它的误差特性也不同。在实际使用,特别是质量检测中,需要确切计算出各测量点的误差,判断测量值是否超差。本文将讨论欧姆表的一些误差问题。 One difference between an ohmmeter (an ohm file of a magnetoelectric system, such as a multimeter) and one of the other meters used in middle school is that the scale of the ohmmeter is non-linear, and therefore its error characteristics are also different. In actual use, especially in quality inspection, it is necessary to accurately calculate the error of each measurement point and determine whether the measurement value is over-difference. This article will discuss some of the error problems in ohmmeters.
