How do you perform a material test on a conveyor belt scale?

To correctly material test a conveyor belt scale you should run three weighed material samples. The first two tests are used to determine a repeatable error, if any. Each material sample should be run across the conveyor belt scale continuously at a rate over 50% of the scale's rated capacity. You may find after the first two tests that the ...
