FIG. 6-8 DERIVED LOSS OF WEIGHT SLOPE (INTERPRETED AS NO
CHANGE-IN-WEIGHT)
• By INCREASING the AVERAGES in the Tuning/Control
Menu, you effectively reduce the “Window of Weight
Variations” which effects the Derived Slope of the weight
readings taken at the beginning and end of the TIME-
BASE period. This may improve the performance of the
controller, but in some cases may not be enough to obtain
adequate control at very low feed rates.
