* Smallest component weight for part counting - under lab conditions:
➢There are ideal ambient conditions for high-resolution counting
➢The parts to be counted are not scattered
** Smallest component part for part counting –under normal conditions:
➢There are unsteady ambient conditions (draft, vibrations)
➢The parts to be counted are being scattered
