Field of View
Make sure that the target is larger than the unit’s spot size. The
smaller the target, the closer you should be to it. When accuracy
is critical, make sure the target is at least twice as large as the
spot size.
Distance and Spot Size
As the distance (D) from the object increases, the spot size (S) of
the area measured by the unit becomes larger.
Reminders
Not recommended for use in measuring shiny or polished metal
surfaces (stainless steel, aluminum, etc.). See Emissivity.
The unit cannot measure through transparent surfaces such as
glass. It will measure the surface temperature of the glass
instead.
Steam, dust, smoke, etc., can prevent accurate measurement by
obstructing the unit’s optics.
Emissivity
Most organic materials and painted or oxidized surfaces have an
emissivity of 0.95 (pre-set in the unit). Inaccurate readings will
result from measuring shiny or polished metal surfaces. To
compensate, cover the surface to be measured with masking
tape or flat black paint. Allow time for the tape to reach the same
temperature as the the material underneath it. Measure the
temperature of the tape or painted surface.
Maintenance
Lens Cleaning: Blow off loose particles using clean compressed
air. Gently brush remaining debris away with a camel's hair
brush. Carefully wipe the surface with a moist cotton swab. The
swab may be moistened with water.
Note
DO NOT use solvents to clean the plastic lens.
Case Cleaning: Use soap and water on a damp sponge or soft
cloth.
Note
DO NOT submerge the unit in water.
