Emissivity

The amount of infrared
energy radiated by an
object depends on its
emissivity and its
temperature.
The emissivity depends
on the material and its
surface characteristics.
For more accurate
readings, adjust the
emissivity value for the
type of material being
measured.
ADJUST EMISSIVITY
The "Setup" DIP switch
(located inside the unit's
handle) must be in the
"ON" position to adjust the
emissivity.
When the trigger is pulled,
the display will show an
emissivity value (4). To
set it to another value,
use the up and down keys
(C).
See the Emissivity
