Acceptable simulated test. Chains do not provide a traceable conveyor scale calibration standard. Heavy chains are difficult to handle. Conveyor belt must be stopped to apply and remove test chains. Linearity test requires several chains.
Chains are costly.
Test weights Static Test Weights Advantages 1. Simulates some conveyor belt effects. Easy to apply. Conveyor belt does not have to be stopped to apply weights. Linearity test easy to perform.
