摘要： A clamp type galvanometer comprising a current transformer constituted from a coil-wounded split iron core pivotally secured so that it can be opened or closed, a lever for opening or closing said split iron core, a meter assembly consisting of a pointer and graduations for indicating the output of said current transformer through a cut-over circuit in the measuring range, and a grip for actuating said cut-over circuit in the measuring range. The device is compactly housed in a case of a size portable with one hand.
