Counting scales and other scales with counting function

General explanation
By means of the total weight of a pre-weighed sample the scale calculates the weight of one piece. This weight of reference is saved in the scale's memory in advance. Next the number of any quantity of the same item can be calculated, such as screws, parts, in short all articles of which one wants to determine the number in a fast and reliable way. The number can be read in the display.

The larger the number of items used for the sample from which the weight of one piece is determined, the more exact the result of counting will be. After all the articles can differ relatively slightly. Thus put a quantity as large as possible on the scale for determining the weight of one piece.

A counting scale does not calculate prices and the counting function is not ment for comercial use. A counting scale is sometimes confused with a price computing scale. As a matter of facts a price computing scale is scale and cashregister at the same time and indeed this can calculate prices by multiplying unit price and weight or number.

Counting scales
A counting scale has 3 display windows (for quantity, piece weight and total weight) and any number for determining the weight of one piece can be inserted by means of the numeric keys.

Ordinary scales (e.g. bench scales) with counting function
An ordinary scale with counting function has one (larger) display, on which either number or total weight is displayed, depending form the selected mode. With an ordinary scale with counting function one has to choose between fixed preset values when determining the weight of one piece, for instance 10, 20, 50 or 100 pieces, because numerical keys are not present.

With all versions one can determine the number of a certain quantity of the same articles, provided that the maximum capacity will not be exceeded. One can repeat the procedure unrestrictedly, because the piece weight stays in memory until it is deleted.
