polished metal object will emit less thermal radiation than
an object with a flat black finish at the same temperature,
and thus appear colder. The temperature displayed by the
camera for the polished metal object would therefore be
inaccurate, unless the camera’s emissivity setting is adjusted
to match the emissivity of the object.
Emissivity of a material surface is difficult to estimate since
it depends on its texture, color, and temperature. A good
default setting is
ε
=0.95. The emissivity of this camera can be
adjusted from 0.01 to 1.00. In addition, there are 4 preset
emissivity settings provided to make it easy to use the
camera in common measurement situations: Matte (0.95),
Semi-matte (0.85), Semi-glossy (0.60), and Glossy (0.30).
Setting the Emissivity
Press the “ / MENU” button to enter the main menu and
select “ ε Emissivity” and press the “ ” button to enter the
emissivity list.
