Patent ID: 8063320

Claim:
An electronic balance, comprising: a load detecting section, for continuously detecting a total load value (W) of a plurality of to-be-measured objects placed on a weighing pan; a moving average processing section, for calculating a moving average (Wa) of the detected load value (W); a load change calculating section, for calculating a load change (Wb) of the detected load value (W); a unit weight storage section, for storing a unit weight (Wu), which is a mass of each of the to-be-measured objects; a moving average start threshold calculating section, for calculating a moving average start threshold (Wt) from the unit weight (Wu), wherein the moving average start threshold (Wt) is used as a criterion to determine whether or not a moving average process is executed; a determination section, for determining from the moving average start threshold (Wt) and the load change (Wb) on whether or not the moving average process is executed; a number-of-objects calculating section, for counting a number (Nwa) of the to-be-measured objects from the moving average (Wa) and the unit weight (Wu) when the moving average process is being executed, and counting a number (Nw) of the to-be-measured objects from the load value (W) and the unit weight (Wu) when the moving average process stops; and a display section, for displaying the calculated numbers (N w , Nwa) of the to-be-measured objects.
