5.1 Field of view

(FOV) ratio=distance to diameter (DS) ratio.
The field of view is the angle of vision at which the instrument operates,
and is determined by the optics of the unit. The FOV is the ratio of the
distance from the target to the target diameter. The smaller the target,
the closer you should be to it. When the target diameters is small, it is
important to bring the thermometer closer to the target to insure that
only the target is measured, excluding the surroundigs.
