The weight values that are shown on the indicator of an industrial scale are of critical importance to the scale operator. A bench scale may be weighing small packages. Or a parts counting scale may be determining the number of parts in a container. Larger drum scales and platform scales may be determining the amount of liquid in a tank or dewar or drum. And large floor scales will be weighing totes, pallets and large tanks. Besides reading the weight information, the operator of the electronic scale can also perform certain control functions, such as applying a tare weight, zeroing the weight on the scale, and choosing the units of measurement, such as pounds or kilos. While it is required and expected that all digital scales provide all of this functionality [+]

Counting parts by hand is inefficient, inaccurate and impractical. Whereas it may be suitable to count ten pieces into a package, it becomes cumbersome and unwieldy to count twenty five, fifty or one hundred pieces by hand. It becomes downright impossible to accurately count one thousand pieces or even more by hand. Parts counting scales are an ideal tool to use for counting parts that are identical in weight. Items such as bolts, screws, nuts, rivets, washers and other fasteners would fit this criteria. Similarly, electrical contacts, connectors, resistors, diodes, and integrated circuits would also be suitable. The scale operator places a small sample of parts on the digital scale platform, and through the keyboard, enters the number of parts in the sample. The industrial scale then calculates the weight of a single part. At this point, as parts are added [+]
