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.

※If 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.
