574 Emissivity - Explanation and Adjust 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. Reflected energy Emitted energy Transmitted energy Target EMISSIVITY EMISSIVITY ADJUST EMISSIVITY To adjust the emissivity value, press EMISS (P). 5 Use the Up and Down keys to select "Free" ("Free" will have a C flashing underline) (7). Press EMISS again. "Free" is not underlined, P and the emissivity icon (5) flashes. Use the Up and 7 D Down keys (C) to adjust. Press ENTER (D) to activate this setting. 14

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

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.
