ABSTRACT:
An electronic weighing scale includes a body for use on a horizontal surface for a weighing operation, a display on the body for displaying a measured weight, and an electronic weighing circuit in the body for measuring the weight of a person standing on the body. The weighing circuit includes a zero-reset circuit for resetting the measurement to zero prior to a weighing operation. The body includes a zero-reset member incorporating an electrical switch operable by the zero-reset member to trigger the zero-reset circuit. The zero-reset member engages the surface, when the body is placed on the surface, for operating the switch to trigger the zero-reset circuit.
