ABSTRACT OF THE DISCLOSURE LIGHT LOAD ADJUST APPARATUS FOR ELECTRIC METER A light load adjustment for an electric meter includes a frame attachable to a core of a voltage coil and a pole-shading element slideable with respect to the frame. The pole-shading element includes a windowed plate or a pair of tabs interposeable between the core of the voltage coil and the rotatable disk and effective to change the direction and magnitude of the torque applied to rotatable disk of the electric meter at light load. A single adjusting screw for the light load adjustment is placed in one of its two alternative positions. In either of its two alternative positions, rotation of the head of the adjusting screw by a worker facing the head produces a displacement of the windowed plate or tabs which tends to change the disk speed in a sense which is consistent with the convention for the relationship between the direction of rotation of an adjustment and the change in disk speed.
