10.3 Counting The "Counting" application enables several parts to be counted on the weighing plate. The scale requires the average piece weight to determine the number of pieces. For this purpose, a defined number of parts is placed on the scale as a reference quantity. This number is used to calculate the average piece weight, which serves as the basis for the count.
