ammeter[am´mE´´tur] Pronunciation Key, instrument used to measure the magnitude of an electric current of several amperes or more. An ammeter is usually combined with a voltmeter and an ohmmeter in a multipurpose instrument. Most ammeters are based on the d'Arsonval galvanometer and are of the analog type, i.e., they give current values that can vary over a continuous range as indicated by a scale and pointer or digital readout.
