Abstract
A vibrating tray scale capable of detecting small amounts of loose particulate matter contained within a mail piece is disclosed. The scale is provided with a clamping device having a plurality of clamping positions. Utilizing different clamping positions, the mass of a mail piece is determined two times, one not including the mass of any loose particulate matter within the mail piece and one including the mass of any loose particulate matter within the mail piece. A determination of whether or not the mail piece contains any loose particulate matter can be made based on a comparison of the results for the two mass determinations.
