Self-aligned light load adjustment assembly for induction meters

An induction meter including a voltage and a current magnetic section each producing magnetic flux and a rotatable disk driven at a rate responsive to said magnetic flux directed from said magnetic sections into said disk, wherein said voltage magnetic section comprises:

• a substantially E-shaped laminated magnetic core having a center leg terminating at a main pole face and two adjacent legs terminating at coplanar auxiliary pole faces on opposite sides of said main pole faces, said first and last laminae defining a first and a second side, respectively, of said core;
• a voltage coil wound about said center leg;
• a voltage shunting member located in magnetic proximity to said first side for providing a magnetic flux shunt path between said pole faces;
• a nonmagnetic spacer located between said first side and said voltage shunting member and lying in a plane substantially parallel to said first side, a portion of said spacer extending beyond one of said adjacent legs in a direction opposite from said center leg and including means for supporting a screw;
• a screw carried by said screw support means of said spacer extending portion;
• a movable tab having a threaded portion cooperating with said screw, said tab being oriented so as to extend over portions of one of said auxiliary pole faces and said main pole face thereby providing an adjustable magnetic flux shunt path.
