DIGITAL VOLTMETER Meaning and
Definition
-
A digital voltmeter (DVM) is an electronic measuring instrument used to measure electrical potential difference, commonly known as voltage, in a digital format. It is a type of voltmeter that can display voltage values in numerical form on a digital screen.
The DVM works by converting the analog voltage signal into a digital format using an analog-to-digital converter (ADC). The voltage to be measured is applied to the input terminals of the DVM, and the ADC continuously samples and digitizes the voltage signal at regular intervals. The resulting digital data is then processed and displayed on the screen.
Digital voltmeters provide accurate and precise readings due to the high resolution of the digital display. They often have various measurement ranges, allowing users to select the appropriate range depending on the magnitude of the voltage being measured. Some DVMs also offer additional features, such as auto-ranging, which automatically selects the best measurement range for the applied voltage.
Digital voltmeters are commonly used in electronics, electrical engineering, and other fields where voltage measurements are required. Their digital display and high accuracy make them more convenient and reliable than traditional analog voltmeters. They are also frequently used in laboratories, manufacturing industries, and in troubleshooting electrical systems to measure voltage levels accurately.

Etymology of DIGITAL VOLTMETER
The term "digital voltmeter" is derived from the combination of the words "digital" and "voltmeter".
- "Digital" is derived from the Latin word "digitus", meaning "finger" or "toe". It originally referred to the numerical system based on the use of fingers for counting. Over time, "digital" came to be associated with numerical values and representation using digits or numbers.
- "Voltmeter" is a compound word consisting of "volt" and "meter". "Volt" is named after the Italian physicist Alessandro Volta, who invented the first electric battery. "Meter" comes from the Greek word "metron", meaning "measure". Therefore, "voltmeter" is a device used for measuring voltage.
