Abstract
A platform scale uses a method of detecting a center-of-gravity (COG) offset. A weight value of a load on a weighing platform is calculated. The weighing platform is allowed to reach a steady state. When the weight value exceeds a COG offset threshold, then a position of a load COG is calculated using a load COG position algorithm. Whether the calculated position is in a valid region of the weighing platform is determined. The weight value is displayed if the position is within the valid region; otherwise, the position of the COG is displayed. A display apparatus of the scale displays the weight value or the position of COG of the load. The platform scale alerts a user about a possible invalid weighing event by displaying an image indicative of the COG offset condition, ensuring effective and precise weighing.
