A digital voltmeter (DVM) is an electronic device used to measure electrical voltage. It is a digital version of the traditional analog voltmeter and provides a numerical readout of the voltage value being measured. Instead of a moving pointer on a scale, a digital voltmeter displays the voltage measurement directly on a digital screen. Digital voltmeters typically use an analog-to-digital converter (ADC) to convert the analog voltage signal into a digital format. The ADC samples the voltage signal at regular intervals and assigns a binary value to represent the voltage level. This digital value is then displayed on the screen. Digital voltmeters offer several advantages over analog voltmeters. They provide greater accuracy and resolution, making it easier to read and interpret voltage measurements. They also offer faster response times and can handle a wider range of voltages. Digital voltmeters are commonly used in various fields such as electronics, electrical engineering, telecommunications, and automotive industries. They are portable, easy to use, and provide precise voltage measurements, making them a valuable tool for both professionals and hobbyists. Digital voltmeters usually have a set of input terminals where the test leads or probes are connected to the circuit under measurement. Overall, digital voltmeters provide convenient and accurate voltage measurements, making them widely used in various fields, including electronics, electrical engineering, automotive diagnostics, and general troubleshooting.
