A digital voltmeter is designed to provide readings in a numerical format, displayed on an electronic screen. This clear numerical representation allows for easier reading and interpretation compared to an analog voltmeter, which utilizes a moving needle to indicate the voltage level on a dial. This difference in display method contributes to the popularity of digital voltmeters in various applications, especially in scenarios requiring precise measurements.

In addition to the clarity of reading, digital voltmeters often include features such as auto-ranging and data hold functions, which enhance their usability. The lack of moving parts in digital models also typically makes them more durable and less prone to mechanical failure than their analog counterparts, which rely on physical components that can wear out over time.
