Abstract

A scale includes a load detection unit detecting a load to a placing unit, a storage unit storing a zero point in advance, a calculation/control unit calculating a load calculation value using a load signal corresponding to the load to the placing unit, based on an output of the load detection unit, and a display unit displaying the load calculation value. When a load is applied to the placing unit, the calculation/control unit calculates a loading state load calculation value based on the load signal in a loading state and the zero point of the storage unit. Subsequently, when the load is removed from the placing unit in a non-loading state, the calculation/control unit calculates a non-loading state load calculation value based on load signals in the loading and non-loading states, and displays the non-loading state load calculation value on the display unit.
