DISCRIMINATION
The
AT Pro has 12 pixels or "notches" of discrimination (in
addition to the 40 points of High-Res Iron Discrimination).
Any combination of these pixels can be switched on or off
based upon your preference. There are two primary methods
for modifying the Notch Discrimination Pattern to reject a
specific type of trash or unwanted item.
The first method uses the NOTCH DISC and ELIM
pushbuttons (seen above) to manually modify the Lower
Scale's Notch Discrimination pattern.
