Limit teaching
This teaching method is recommended, if small objects or objects in the
background exist.

1-point teaching (window comparator mode)
This mode is used for setting the threshold range for the distance from the
reference value of the sensing object by performing a 1-point teaching. This
mode is used for sensing within the threshold range.
When performing the 1-point teaching (window comparator mode), preset
"Window comparator mode 1" in the sensing output setting of the PRO
mode. For the setting method, refer to section 13, "PRO mode setting."

2-point teaching (window comparator mode)
This method is used to set the threshold range by conduction the 2-point
teaching.
When performing the 2-point teaching (window comparator mode), preset
"Window comparator mode 2" in the sensing output setting of the PRO
mode. For the setting refer to section 13, "PRO mode setting."
When conducting the teaching, use sensing objects (P-1 and P-2) whose
distance are different from each other.
