What is the primary function of a Digital Volt Meter (DVM)?

The primary function of a Digital Volt Meter (DVM) is to measure voltage. A DVM is specifically designed to assess the electrical potential difference between two points in an electric circuit, which is expressed in volts. This measurement is crucial in a variety of applications, from simple electronic device testing to complex electrical circuit analysis.

By displaying voltage readings digitally, a DVM provides a more accurate and easier-to-read result compared to analog voltmeters. This accuracy is particularly important while diagnosing circuits, ensuring that the voltage levels are within appropriate ranges for safe and efficient operation.

While a DVM can often have additional functionalities, such as measuring current and resistance, its primary role centers on voltage measurement. Other instruments are typically used to focus more specifically on measuring current or analyzing circuit efficiency, highlighting the DVM's unique specialization.
