Adjusting Emissivity
The amount of infrared energy radiated by an object depends on emissivity and
temperature. The emissivity depends on the material and its surface characteristics. For
more accurate readings adjust the emissivity value for the type of material you are
measuring. See Appendix C for typical emissivity values of various metallic and
non-metallic sources.
As emissivity changes, the live thermal image will also change as the displayed
temperature changes. The default emissivity setting is 0.95 and the adjustmentment range
is from 0.01 to 1.00.
1. From the Home display, press G (
MENU
) three times to navigate to the Adjust
Emissivity and RTC display.
