An apparatus for measuring the weight of items on a conveyor includes a scale that generates a first signal corresponding to the weight of the items. A movable platform transports the items to the scale and generates a second signal corresponding to position of the items in relation to the scale. A dimensioner examines the items and generates a third signal representative of whether the items are singulated or nonsingulated. A processor receives the second and third signals and determines whether to associate the first signal with information stored in memory about a particular item based upon whether the particular item is singulated or nonsingulated.
