XM-INDIA AC 230 Voltmeter Round Red Yellow Green Combo Voltmeter  (Digital)

A digital voltmeter is an electronic measuring instrument used to measure voltage levels. Unlike analogue voltmeters that use a pointer or needle on a scale to indicate voltage, digital voltmeters display the measured voltage as numeric values on a digital display, such as LED screen. Digital voltmeters typically operate based on the principle of analog-to-digital conversion. They convert the incoming analog voltage signal into a digital format, allowing for accurate and precise voltage measurements. Digital voltmeters can measure AC (alternating current) and provide readings in volts (V) or millivolts (mV). Digital voltmeters offer several advantages over their analogue counterparts. They provide better accuracy, higher resolution, and often have additional features like autoranging (automatically selecting the appropriate measurement range), hold function (freezing the displayed value), and peak voltage measurement. They are also more immune to noise and interference. They are widely used in various industries, including electronics, electrical engineering, telecommunications, automotive, and scientific research, for measuring and troubleshooting voltage levels in circuits and systems.
