8-15-4-4 Atmospheric Transmission
The imager has atmospheric transmission compensation to correct environmental
sources of energy. Temperature readings are especially sensitive when the
emissivity of the object is low or the difference between the object temperature
and the ambient temperature is large.
Set the atmospheric transmission as follows:
1.
Press the Review button to open the image gallery.
2. Press-and-hold on the screen; then, drag up or down to scroll through the
image gallery. Locate a video by tapping the Videos icon at the bottom of
the screen.
3. Tap on media to open it in the Review Area.
4. Tap Edit to open the Analysis Area.
5. Tap Parameter (abbreviated Param) tab.
6. Tap Atmospheric Transmittance (abbreviated Atmos Transm). A rotary
menu appears.
7. Press up or down on the Thumbstick to select a transmission percentage.
8. Press the Back button to save and exit the rotary menu.
9. Press the Back button repeatedly to exit processing.
8-15-4-5 Optical Transmission
The accuracy of temperature readings is dependent on the physics of the scene.
Errors in temperature measurements are mainly caused by two things: (1) the
variation of the emissivity value, (2) the temperature range.
Ensure all physics values are entered into the camera’s settings; then, compensate
for transmission as follows:
1.
Press the Review button to open the image gallery.
2. Press-and-hold on the screen; then, drag up or down to scroll through the
image gallery. Locate a video by tapping the Videos icon at the bottom of
the screen.
3. Tap on media to open it in the Review Area.
4. Tap Edit to open the Analysis Area.
5. Tap Parameter (abbreviated Param) tab.
6. Tap Optical Transmission (abbreviated Optical Transm). A rotary menu
appears.
7. Press up or down on the Thumbstick to select a transmission percentage.
8. Press the Back button to save and exit the rotary menu.
9. Press the Back button repeatedly to exit processing.
