or the touch screen to increase or widen the
temperature span.
2. Push
or the touch screen to decrease or narrow the

Emissivity Adjustment
The correct emissivity values are important for the Imager
to make the most accurate temperature measurement
calculations. Emissivity of a surface can have a large
effect on the apparent temperatures that the Imager
observes. Understanding the emissivity of the surface
being inspected can, but not always, allow you to obtain
more accurate temperature measurements.
If you set a value that is <0.60, shows on the Imager
display with this caution:
Caution:
Emissivity <0.6
