Setting Emissivity (Spectral mode)

A pyrometer measures temperature by detecting the radiant energy emit-
ted from an object's surface in the form of electromagnetic waves. The
temperature reading not only depends on the intensity of the object's
thermal radiation (how hot the object is), but also on the material's par-
ticular surface characteristics and thus its specific ability to emit thermal
energy. This is called emissivity. To obtain an accurate temperature
