Spot Size to Distance

F
The measured surface area can represent a cone emanating out from the
sensor. The further the distance to the surface, the larger the area that will
influence temperature measurements. It is important that when it safe to
do so, get as close as possible to the target, using the dual lasers to define
the perimeter of an imaginary circle. This will increase the accuracy of the
displayed temperature. Also, make measurements at 90 degrees to the surface
as angular measurements are less accurate. (Reference diagram below)
