Switch the divert valve to the DIVERT position.
The test interval will decrement every second. When this time interval reaches zero the divert valve will automatically
switch to the DIVERT position.
8)
After the sample is taken, verify that the computer totalizer has stopped accumulating.
9)
Weigh the asphalt in the truck. Compare this actual weight with the metered weight shown on the display. If the
metered weight is within tolerance and recalibration is not required the user can ESCape from this procedure or
return to Step 4 and run a subsequent test.
10)
Select Option 8 to recalibrate the meter to the actual weight. See Figure 8656.4If the user enters an actual total
different from the displayed metered total, the A/C meter span calibration value will automatically be recomputed
so that, if the test could be repeated exactly, the metered total would now equal the actual total entered.
11)
As necessary, verify the new span calibration by repeating this procedure starting at Step 2.
12)
Upon satisfactory calibration, verify that no other span numbers have changed from the original data printed in
Step 2.
