Test chain calibration is used for testing mechanical belt scales, and to calibrate high capacity electronic belt scales and weighfeeders that cannot be calibrated using material tests. During the calibration, the test chain is applied to the conveyor belt and is secured at both ends so that the chain remains stationary over the weighing length.
Develop a safe system of work to allow calibration of the weightometer while the conveyor is running. Implement competency-based training for work done on conveyors where there is the risk of exposure to rotating and moving parts. Further information .
