In a dynamic scale, and a method for controlling a dynamic scale, an item to be weighed is transported by a transport device to a weighing cell. The apparatus further includes a fiber clamp connected to mounting base for securing a first portion of the fiber optic cable. The first recess and the protrusion are arranged at the predetermined angle to position the notch of the disk and the shaft pin of the scrubber for proper assembly at the predetermined angle with respect to the longitudinal axis of the shaft. A material code mapping agent compares the material code with at least one material code mapping table to identify corresponding computational component information associated with the material code. The shelf further has a pivotable tab formed in the peripheral frame portion, which pivots to engage the plate upon mounting of the bracket to the frame.
