多用电表又称万用表,是一种多功能、多量程的仪表,其原理简单,用途广泛,使用方便,是一种常用的测量仪表和重要的电学工具。一、为什么多用电表可以进行多功能、多量程电学量的测量多用电表由表头、测量电路、转换开关三部分组成。表头指示部分有多条标度尺的刻度盘;测量电路是多用电表的重要部分,主要由表头、定值电阻、变阻器、二极管等部件组成。将表头G串联不同的电阻实现多量程直流电压的测量,将表头G并联不同的电阻实现多量程直流电流的测量,
Multimeter, also known as multimeter, is a multi-function, multi-range instrument, the principle is simple, versatile, easy to use, is a commonly used measuring instruments and important electrical tools. First, why multi-meter can be multi-function, multi-range electrical measurement Multimeter from the meter, measurement circuit, the switch is composed of three parts. Meter indicates the first part of the scale of the dial scale; measuring circuit is an important part of multimeter, mainly by the meter, resistors, varistors, diodes and other components. The header G series of different resistance to achieve multi-range DC voltage measurement, the header G parallel different resistance to achieve multi-range DC current measurement,
