6. Counting Pieces
To implement piece-counting, the specified samples are loaded on the balance, and their average unit
weight (hereinafter, simply the "unit weight") is entered and saved. The procedure for saving unit
weights is called sampling.
The counting procedure consists of loading articles that have already been sampled on to the balance.
The number of pieces is then calculated by dividing the total weight of the loaded articles by the unit
weight saved in memory. Piece counting cannot be implemented unless sampling has already taken
place.

JKIf samples to be counted deviate widely in weight, or a higher measure of accuracy is desired, it is
recommended that users use the "Raising the Counting Accuracy" method. This procedure results
in greater precision by increasing the number of samples used in the sampling operation.
