Ammeternoun
A device that measures the magnitude of an electric current, especially one calibrated in amperes.
Ammeternoun
A contraction of amperometer or ampèremeter.
Ammeternoun
a meter that measures the flow of electrical current in amperes
Ammeter
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.
Multimeternoun
An electronic measuring instrument that combines multiple functions; a combined voltmeter, ammeter and ohmmeter.
Multimeter
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.
