What are the Characteristics of the Digital Multi-function Meter? Principle of Multi-function Meter
A digital multi-function meter is a meter that displays the measured value digitally. An instrument that converts measurements into digital quantities and displays them in digital form. In industrial measurement, the measured variables or analog quantities such as displacement, current, voltage, and air pressure are converted into digital quantities through an analog-to-digital converter (referred to as analog-to-digital conversion).
