Abstract: Systems, methods and non-transitory storage medium are disclosed herein for adjusting an output of a particle inspection system representative of a particle characteristic for a particle flowing in a flow-path of a particle processing system. More particularly, the output may be processed and a calibrated output of the particle characteristic generated. In other embodiments, one or more calibration particles are used. Thus, an output of a particle inspection system representative of a particle characteristic for one or more calibration particles flowing in a flow-path of a particle processing system may be compared relative to a standard and an action may be taken based on a result of the comparing the output to the standard.
