Reflected Background Temperature Compensation; Transmission/Transmittance Adjustment - Fluke TiR105 User Manual

Reflected Background Temperature Compensation

Compensation for reflected background temperature is set in the Background tab.
Very hot objects or very cold objects can affect the apparent temperature and
measurement accuracy of the target or object of interest, especially when surface
emissivity is low. Adjustment of the reflected background temperature can make
the temperature measurement better in many situations. For more information, see
Emissivity Adjustment.

Transmission/Transmittance Adjustment

When you do infrared inspections through infrared-transparent windows (IR
windows), not all of the infrared energy emitted from the objects of interest is
transmitted through the optical material in the window. If the transmission
percentage of the window is known, you can adjust this percentage in the Imager
or in the SmartView software. Adjustment of the transmission correction can
make the accuracy of the temperature measurement better in many situations.
