Surfaces with an emissivity of
consistent actual temperatures. The lower the emissivity is the greater the
potential of error is when the Imager calculates the temperature measurement
because more of the energy reaching the camera is specified as background
temperature. This is also true even when adjustments to the emissivity and
reflected background adjustments are performed properly.

Spot Box

Use the Spot Box feature to adjust a temperature measurement zone (box) to center on the

measurement in that area.
When using the Spot Box, the level and span of the Imager adjusts to the thermal
