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.
