Patent ID: 8670951

Claim:
An electronic scale having an air pressure change compensation function, comprising: a measuring plate on which an object to be weighed is placed; a load detection unit for detecting a weight of the object to be weighed; an air pressure measurement unit for measuring air pressure when the load detection unit detects the weight of the object to be weighed; a signal conversion unit for converting each detected signal into a digital signal using Analog/Digital (A/D) conversion; an air pressure compensation calculation unit for calculating a difference between air pressure obtained upon zero point adjustment and air pressure obtained upon measuring the weight of the object to be weighed, based on the signal output from the signal conversion unit; a measured weight calculation unit for correcting a measured weight by taking into consideration the air pressure difference calculated by the air pressure compensation calculation unit; and a display control unit for displaying a resulting measured weight finally calculated by the measured weight calculation unit and controlling an overall operation of the electronic scale, the display control unit having a display hold button for holding displaying the measured weight, or a display delay button for delaying display time of the measured weight.
