Abstract
A register pointer for an electric utility meter is described as having a weakened section at which fracture can occur to break away the pointer when an attempt is made to tamper with the pointer, such as by manually resetting the pointer's position on the register to show a lower reading of energy consumption. Various forms of breakaway means are described which will permit separation of the pointer portion of the device from its shaft portion when a torque is applied to the pointer end.
