Recipe Setup for Extrusion:
1.Turn power switch to ON position.
2.Press 
Input to display # 1, “Additive %”. Using arrow keys, set additive ratio.
3.Press 
Input to display # 2, “Throughput of extruder”. Using arrow keys, set the total extruder throughput in g/min or lb/min.
4.Press 
Input to display # 3, “Extruder screw speed”. Using arrow keys, set the extruder screw speed RPM expected during production.
NOTE: For Extrusion - Constant operation, the above step will be skipped.
5.Press Input to display # 4, “Calibration weight for additive”. Enter the appropriate value from the range table on page 9 and proceed to calibration mode below for calibration of additive material.

1. Press | “Calibration” button to start this procedure. Display will show - - - - |
2.Place the plastic calibration cup on the scale and tare so that the weight of the cup (approx. 24 grams) is not calculated in the calibration procedure.
3.Remove cover of the calibration box, secured by two 5 mm Allen screws, under the dosing disc assembly and insert plastic cup provided in top of dosing hopper.
4.Press 
“Run” and the dosing disc turns 1/4 turn. This fills all pockets of dosing disc. Dump the dosed material back into the dosing hopper without weighing and replace plastic cup in calibration box.
5.Press 
“Run” and the dosing disc turns 1 complete revolution. Remove the calibration cup with the material and place on the gram scale. Enter the weight on the
scale into the controller 
using the arrow keys. Empty and replace calibration cup.
6.Repeat step # 5 four more times, each time entering the new weight from the scale into the controller using the arrow keys. Sometimes the values won’t change, or sometimes they may only change by a few tenths of a gram. The controller keeps a running average of all calibration weights entered.
