ACAI Counting Mode (pcs) Found on the A&D Line of Counting Scales

One of the most powerful and useful features of FC-i Counting Scale Series is ACAI, Automatic Counting Accuracy Improvement. It is not a new feature but a feature AND had incorporated to the first generation of FC counting scales in order to maximize the accuracy of counting without sacrificing ease of use. However, once in a while the factory is asked why it is there or even if it can be removed. The reason is simply that some operators do not understand how it works. Since the theory behind the ACAI involves some knowledge of statistical mathematics about errors, it sometimes discourages people to even try to understand what it is. In actuality it is a result of the careful observation of how a counting scale is being used at workplaces.

While accurate and stable weighing or well-designed solid hardware is a must for a scale to do accurate counting, one basic norm for a counting scale is that the bigger internal resolution it has, the more accurate counting it gives. For instance, let’s take the example of a scale with internal resolution of one part by 3,000; in other words, a scale of 3kg capacity by 1 gram resolution. When one counts materials lighter than 1 gram per piece with this scale, for instance 0.1 gram apiece, it means 10 pieces make one gram. Thus when counting, the scale can detect a change in weight only when 5 or more pieces that are equal to the half of the scale’s increment are added. When you want to count up to 300 pieces, it can be 295 through 304 since the last digit stays zero because of the limitation of its internal resolution. The weighing result always has an error of +/- 5 pieces. Take a look at the FCi for more on the ACAI feature.
