6. Temperature measurement
Point the product to target objects, hold the trigger to read the temperature. The distance and target area: the value of D
(distance): S (spot) must be considered (as showed), the ratio should be no more than the value of D:S. The field of view
must be full of objects. As the distance from the object increases, the spot size of measuring area becomes larger.
Field of view: Be sure the target area is larger than the unit’s spot size. The smaller the target get, the closer the measured
distance. For precise measuring, make sure the target is at least twice as large as the spot size. The light-emitting device
