Set the threshold to be applied when the machine recognizes an
outline-recognized component.
- 0” is set as the initial value. If the machine cannot recognize such a
component, adjust the initial value between – 127 and + 127. When a
component looks darker, set the smaller number. When you can see even
the background of a component, increase the value.

Notes:
The machine cannot recognize images of an extended-lead connector with
dividing it.
Note that only one point, the rightmost lead position is set on this screen, so
the recognition precision is insufficient.
