    The invention discloses a moving iron (electromagnetic type) AC current/voltage meter, comprising: a meter casing, a meter dial, a pointer and an electromagnetic movement for driving the pointer, where the electromagnetic movement is a coil bracket wound with a coil, one end of the coil bracket is fixed with a rotating shaft bracket, the hollow inner wall of the coil bracket is provided with a stator bracket fixed with a stator, the rotating shaft extending into the hollow part of the coil bracket is provided with a rotor, and the stator and rotor match. The invention omits a transformer and a circuit connected with it, reducing bulk and improved into a flow of power input-induction coil-magnetic repulsion-point deflection. And the meter dials can be unitedly printed without manual regulation, thus raising accuracy and sensitivity and reducing product cost.
