Spot Sizes:
Ensure the ISR 320 is using a proper focused distance and takes into account
the spot size in relation to measuring distance.
In the 1-color (mono) mode, the pyrometer can measure objects at any distance.
However, the object has to be bigger than or at least as big as the spot size of the
pyrometer in the measuring distance.
In the 2-color (ratio) mode, the object can be somewhat smaller than the spot
diameter.
Additional information on this topic can be found in Section 3.3 Optics.
Obscured Window:
Clean the window. Refer to Section 6.1.
