.................................................................................................................................................. Aggregate Scale Calibration
10)
After the truck is filled, verify that the displayed rate returns to very nearly zero and the totalizer has stopped
accumulating. If this is not the case, there may be scale problems that will affect the validity of the calibration. The
most common problem is a buildup of material on the conveyor belt during the test.
11)
Weigh the aggregate in the truck. Compare this actual weight with the measured scale weight shown on the
display. If the measured scale weight is within tolerance and recalibration is not required the user can ESCape
from this procedure or return to Step 3 and run a subsequent test.
12)
Select Option 8 to recalibrate the scale to the actual weight. See Figure 8654.4If the user enters an actual total
different from the displayed measured total, the belt scale span calibration value will automatically be recomputed
so that, if the test could be repeated exactly, the measured total would now equal the actual total entered.
13)
As necessary, verify the new span calibration by repeating this procedure starting at Step 3.
14)
Upon satisfactory calibration, verify that no other span numbers have changed from the original data printed in
Step 3.
