Belt Speed Compensation

To achieve optimum accuracy in the rate computation, the belt speed displayed must
equal that of the actual belt speed. As the speeds are likely to differ, a belt speed
compensation should be performed.
Run the conveyor with the belt empty.
View the belt speed.

Stop the conveyor and measure a length of the belt; marking the forward end (start time)
and the back end (stop time). Use the belt scale as the stationary reference.
Run the belt and measure the time for the belt length to pass over the scale.
