Weight measurement apparatus, biological measurement apparatus, storage medium encoded with weight measurement program and method

摘要

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.

1. A weight measurement apparatus comprising:
load detection circuitry configured to detect a load to a loading unit; storage circuitry configured to store a first zero point in advance; control circuitry configured to calculate a first load calculation value and a second load calculation value using a load signal corresponding to the load to the loading unit based on an output of the load detection circuitry; and display circuitry configured to display at least one of the first load calculation value and/or the second load calculation value, wherein the control circuitry is configured to calculate a loading state load calculation value as the first load calculation value which is calculated based on the load signal in a loading state and the first zero point of the storage circuitry, wherein the load is applied to the loading unit in the loading state, wherein the control circuitry is configured to calculate a non-loading state load calculation value as the second load calculation value which is calculated based on the load signal in the loading state and the load signal in a non-loading state wherein the load is removed from the loading unit in the non-loading state and after the loading state, wherein the control circuitry is configured to display the loading state load calculation value calculated in the loading state on the display circuitry, and is configured to redisplay the non-loading state load calculation value calculated in the non-loading state on the display circuitry, and wherein the control circuitry is configured to determine whether to redisplay the non-loading state load calculation value calculated in the non-loading state on the display circuitry in accordance with a determination result regarding a difference between the first zero point stored in advance in the storage circuitry and a second zero point in the non-loading state.
