Ammeter vs. Multimeter — What's the Difference?

An ammeter (abbreviation of Ampere meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in Amperes (A), hence the name.

A multimeter is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case it is also known as a volt-ohm-milliammeter (VOM), as the unit is equipped with voltmeter, ammeter, and ohmmeter functionality.

An instrument for measuring electric currents in amperes.

An instrument that combines an ammeter, an ohmmeter, a voltmeter, and occasionally other measurement or testing devices into one unit.

A device that measures the magnitude of an electric current, especially one calibrated in amperes.

An electronic measuring instrument that combines multiple functions; a combined voltmeter, ammeter and ohmmeter.

A contraction of amperometer or ampèremeter.

A meter that measures the flow of electrical current in amperes
