as indicated by the BW500. The following data was tabulated. (This example is exaggerated for
emphasis).
The material tests should be run at same belt speed, representative of normal operation; in this
case 1.2 m/s. For each rate, record the corresponding load value by scrolling to the BW500 load
display during running conditions or by calculation.
load = (rate/speed)
calculation example: % compensation = [(2.5 – 2.8) x 100]/2.8
