The emissivity is adjustable in 0.01 steps from 0.10 to 01.00. The default value 
is set at 0.95. 

The correct emissivity values are important for you to make the most accurate 
temperature measurements. Emissivity of a surface can have a large effect on 
the apparent temperatures that the Product observes. Understanding the 
emissivity of the inspection surface can, but not always, allow you to obtain 
more accurate temperature measurements.
