电压表（Digital Voltmeter）简称DVM，它是采用数字化

电压表（Digital Voltmeter）简称DVM，它是采用数字化测量技术，把连续的模拟量（直流输入电压）转换成不连续、离散的数字形式并加以显示的仪表。传统的指针式电压表功能单一、精度低，不能满足数字化时代的需求，采用单片机的数字电压表，由精度高、抗干扰能力强，可扩展性强、集成方便。目前由各种单片A/D 转换器构成的数字电压表，已被广泛用于电子及电工测量、工业自动化仪表、自动测试系统等智能化测量领域，示出强大的生命力。与此同时，由DVM扩展而成的各种通用及专用数字仪器仪表，也把电量及非电量测量技术提高到崭新水平。
该系统的数字电压表电路简单，所用的元件较少，成本低，且测量精度和可靠性较高。此数字电压表可以测量0-5V的1路模拟直流输入电压值，并通过LED显示出来。
