Calibration and Verification of Belt Conveyor Scales Belt conveyor scales require periodic calibration and verification to assure that the accuracy and repeatability of the system are being maintained within acceptable tolerances. The four methods commonly used to calibrate and verify a belt scale are: 1. Static Test Weight Calibration 2.
