Digital multimeters are an electrician's best friend. They are gadgets used to measure voltage, current and resistance of a circuit of an electronic device or an in-home circuit. A digital multimeter, or DMM, produces highly accurate numerical readings and displays them on a LED screen. An analogue multimeter, on the other hand, display readings using a pointer that deflects on the printed dial screen. This may produce inaccurate readings resulting from human error. There are different types of DMMs and they function differently.
