Title:
WEIGHING PERFORMANCE CONFIRMATION METHOD FOR SCALE AND SCALE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2022/138124
Kind Code:
A1
Abstract:
The present invention addresses the problem of confirming the weighing performance of an electronic scale under conditions close to those of actual use by a user. In order to solve this problem, an electronic scale (1) comprises a weighing pan (2), a windscreen (3), a gate opening/closing mechanism (12) that automatically opens and closes gates (33, 34) of the windscreen, a weight sensor (11), a built-in counterweight (13), a counterweight loading/unloading mechanism (14) for the built-in counterweight, and a control unit (15). The control unit measures the standard deviation of the built-in counterweight as a standard deviation for actual use (SDreal) in the course of a series of opening and closing actions in which the gates are opened by the gate opening/closing mechanism, the built-in counterweight is loaded by the counterweight loading/unloading mechanism, the gates are closed using the gate opening/closing mechanism, weighing data for the built-in counterweight is acquired, the gates are opened by the gate opening/closing mechanism, the built-in counterweight is unloaded by the counterweight loading/unloading mechanism, and the gates are closed by the gate opening/closing mechanism,
