What is a multimeter?
Also known as a multitester, or a VOM (Volt-Ohm meter), a multimeter is an electronic measuring instrument used to measure voltage, current, and resistance. Includes handheld and tabletop testing devices.
What is a digital multimeter?
Digital multimeters (also called DMM or DVOM) either use a graphical bar representing the measured value or have a numerical display. Multimeters can be hand-held devices for field and basic work or bench instruments that can measure voltage, current, and resistance.
When was the first multimeter invented?
Multimeters were invented in the early 1920s by Donald Macadie, who designed an instrument that could measure amperes (amps), volts, and ohms. This first multimeter was hence called the Avometer. Multimeters generally include a display (either analog or digital), a selection nob, and ports.
When was the first current detecting device invented?
The first current-detecting device was a moving-pointer galvanometer used in 1820 to measure resistance and voltage by using a Wheatstone bridge and comparing the desired, unknown quantity to a reference resistance or voltage.
