Plug load cell cable CBLO13 into plug J13 on control van plug box.3Remove transport chains retaining the calibration tank so that it is supported by the load cell andclear of the support structure.4Install 2 inch asphalt line (stored in the basket on the drum mixer) between calibration tankconnection and the quick coupler at the metering pump.5To calibrate tank, open manual square head plug valve to calibration. Close square head plugvalve to drum mixer.6Feeder panel select DIVERTon Divert valve. Select MANUAL on AsphaltMeteringPump.Select FORWARD on AsphaltMeteringPump. Adjust speed to 50% on AsphaltMeter. Confirmapproximate asphalt flow rate of 5.5 tons per hour.7Open feeder panel lower door to expose calibration scale panel mounted on inside of door.(See figure 2-37).8Press on/off button. Scale should read identification DF2000 and display a numerical value.9Press zero and scale will automatically zero. (See Maintenance manual for more information).10Suspend known weight to the calibration tank (one on each side of calibration tank frame).11Verify scale digital display reads accurately the known weight (within + or one pound). If scaledoes not read accurately proceed to set new span.12Calculate and compare sample weight with computer test weight. If in error, on keyboard, selecterror calculator (8), enter requested values as prompted. Record results on calibration sheet.Select correct totals (9), enter calibrated weight from calibration sheet. Press ESCAPE.13Press 13, press select, display flashes 1 and returns to original weight reading, enter the correct(known) weight and press enter.14Remove calibration known weight.15Check zero. Re-zero if necessary.16Re-apply weight. Repeat steps 11 through 14. Repeat as often as necessary.page 2-92
