Field of View
!
The object under test should be larger than the spot size
calculated by the field of view diagram.
!
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.
⑶
Distance& Spot Size
As distance (D) from the object increases, the spot size (S) of
the area measured by the unit becomes larger.
⑷
Locating a hot Spot
To find a hot spot, first aim the thermometer to the outside of
target area, then scan across in an up and down motion until
the hot spot is located.
⑸
Notice
!
Not recommend for measuring shiny or polished metal
surfaces like stainless steel, aluminum, etc.
! Do not make measurement through transparent surface
such as glass
! If the surface of the object under test is covered with frost,
oil, grease, etc., clean it before taking measurement.
