Digital Multi Meter is a measuring instrument that can measure quantities such as voltage, current, and resistance. These are shown on a digital display that allows them to be read easily and directly even by first-time users. It is an electronic measuring device that combines several measurement functions in one unit. Digital Multi Meter is much easier to read and provides more accurate readings. It is resistance by injecting a small current into the circuit and then measuring the voltage drop across those points in the circuit.
