Description
The ammeter is an instrument for measuring either direct (DC) or alternating (AC) electric current, in ampères. An ammeter can measure a wide range of current values because at high values only a small portion of current is directed through the meter. For DC a shunt in parallel with the meter carries the major portion of the current. For AC an appropriate current transformer (CT) is used. This 0-600 ampère DC flush type ammeter was made by the Weston Electrical Instrument Company, in Newark, New Jersey, United States of America at the beginning of the 20th century (Patent dates: Nov 6 1888 - July 16 1901). 0-600 amp DC. Cast iron with a card face.
