Response speed selection function
Set DIP switch 3 to select whether to output every measured value or
the average of 8 measured values (moving average).
LOW:
Outputs the value of the average of 8 measured values. Offers more
stable detection when the luster of the target varies greatly.
HIGH:
Outputs every measured value. Offers high-speed response when the
target vibrates or moves quickly.

Example: To cancel the influence by surface roughness, LOW is
recommended.
Example: To detect abrupt changes such as height differences,
HIGH is recommended.
