Achieve Accurate Counting Results

A critical consideration in any counting process is accurately counting parts that vary greatly in weight. The deviation in piece weight for each part can be measured using the standard deviation, with high-precision parts having an average piece weight deviation of around 0.5%. 

The impact of average piece weight and deviation on counting accuracy is significant. The higher the standard deviation, the greater the resulting counting error. Additionally, smaller average piece weights require higher counting resolutions to achieve accurate results. 

Not only is it important to select the right equipment, but installing it correctly and getting operators trained is paramount to putting in place a maintenance and calibration plan. Even though industrial scales are designed to withstand harsh manufacturing environments, they must be periodically tested and maintained. Proper scale calibration is especially important when operating a two-scale system. If the sample and counting scale are not periodically calibrated, chances are the counting results are wrong.
