7. Notes
1）Field of View
The smaller the target object is, the closer the meter should be to it for accurate measuring.
When accuracy is critical, make sure the target is at least twice as large as the spot size.
As distance (D) from the object increases, the spot size (S) of the area measured by the unit should become
larger.
