Abstract: This invention relates to a system for and method of determining the accuracy of mail piece weights. The weight of individual mail pieces during a mail run is displayed in real time. A high speed weighing scale is located downstream from the mail processing unit to receive the mail pieces after the mail processing unit has inserted selected materials into envelopes. As each mail piece is weighed, its weight is stored in memory and a display can be made showing all the weights of the individual mail pieces in real time. This display can be temporary, such as on a monitor, or permanent, such as a print out. With such display, an operator has a fast method of determining if the weights are in an expected range.
