Dispersion of the individual weights

The counting accuracy is mainly influenced by the scattering of the weight of the individual parts. Therefore, the weights of 10 different individual parts must first be determined. The smallest part weight should be at least 10 digits - for higher required accuracies 100 digits - of the scale display.
