Description: 数字电压表是以数字化测量技术将被测电压转换成对应的数字量，然后对此数字量进行计数和显示的仪表。数字电压表由两部分组成：模数转换部分和计数显示部分。因为计数部分能获得很高的分辨力，所以，被测电压的准确度主要由使用的模数转换技术决定．-Digital voltage meter digital measurement technology is based on the measured voltage will be converted into the corresponding figures for the volume, and then this figure to count and display the volume of the instrument. Digital voltage meter composed of two parts: analog-digital conversion part and part count display. Count in part because access to high-resolution, so the accuracy of the measured voltage by the use of the analog-to-digital conversion technology decisions.
