Additive Sample weighing.

Weighing samples of additive provides for more precise control of feed rate. Up to 5 samples can be weighed. All weights entered are averaged to arrive at a value to be used during operation. The weighing process may be skipped altogether, in which case the calibration weight is used for calculations of feed rate.

Weight Calibration.

The final step of recipe setup is weight calibration. This procedure is common to all types of presses supported. After entering the calibration weight, pressing the “Next” button displays the following screen:
