Emissivity Adjustment

The correct emissivity values are important for you to make the most accurate
temperature measurements. Emissivity of a surface can have a large effect on
the apparent temperatures that the Imager observes. Understanding the
emissivity of the surface being inspected can, but may not always, allow you to
obtain more accurate temperature measurements.

If you set a value that is

0.60,  shows on the Imager display with this

caution:



Caution:
Emissivity <0.6
(see Manual)

Note

Surfaces with an emissivity of

0.60 make reliable and consistent

determination of actual temperatures problematic. The lower the
emissivity, the more potential error is associated with the Imager's
temperature measurement calculations. This is also true even when
adjustments to the emissivity and reflected background adjustments
are performed properly.

Emissivity is set directly as a value or from a list of emissivity values for some
common materials.

Note

If the Display is set to Display All, you see the information about
current emissivity as

= x.xx.
