Analyzing and Enhancing Images
Setting Emissivity and Background
Temperature
Setting your camera with correct emissivity and background temperature
values is critical to making accurate temperature measurements.
Emissivity values on your camera and saved images are adjustable between
0.01 and 1.00 with increments of 0.01. This value, along with the background
temperature and target radiation measured by the camera, is used to calculate
target temperatures. Use the table in Appendix C, which lists the emissivity
values of some common materials, as a guide to setting correct emissivity
values.
To set the emissivity value for an image in the camera:
1. Use the MOUSE controller to position the pointer over the emissivity
value on the task bar and tap E. (See Chapter 2 for emissivity value
location on the task bar.)
2. Use the up/down MOUSE action to raise or lower the value.
3. Tap the TRIGGER button to accept setting change and return to the open
image.
4. Tap the TRIGGER button again to return to scan target mode.
