数字电压表的基本工作原理是利用A/D转换电路将待测的模拟信号转换成数字信号，通过相应换算后将测试结果以数字形式显示出来的一种电压表。较之于一般的模拟电压表，数字电压表具有精度高、测量准确、读数直观、使用方便等优点。-Digital voltmeter the basic working principle is to use A/D converter circuit to test the analog signals into digital

Signal converted by the corresponding test results will be displayed in digital form as a voltmeter. Than

In the normal analog voltage meter, digital voltmeter with a high accuracy, measurement accuracy, intuitive readings, using

Advantages of convenience.
