digital voltmeter

A digital voltmeter is an instrument used to measure electrical voltages, displaying readings numerically. These instruments generally offer higher accuracy than analog voltmeters, which use a moving pointer on a scale. Digital voltmeters are a type of voltmeter, a device that measures voltages in volts, millivolts, or kilovolts. Other types of voltmeters include electrostatic voltmeters, which measure voltage directly, and electronic voltmeters that use amplification or rectification. A multimeter, also known as a volt-ohm-milliammeter (VOM), can measure voltage, current, and resistance. A voltameter, however, is a different apparatus used to measure the quantity of electricity through electrolysis.12
