Emissivity - Explanation and Adjust

Reflected energy

Emitted energy

Transmitted energy

EMISSIVITY

Target

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.

To adjust the emissivity

value, press EMISS (P).

Use the Up and Down

keys to select “Free“

(“Free

(“Free” will have a

flashing underline) (7).

Press EMISS again.

“Free” is not underlined,

and the emissivity icon (5)

flashes. Use the Up and

Down keys (C) to adjust.

Press ENTER (D) to

activate this setting.
