3.13 To keep in mind

Adjust the focus first. When the camera is out of focus, the measurement will
be wrong.
By default, most cameras adapt the scale automatically. Use this mode first,
but do not hesitate to set the scale manually.
A thermal camera has a resolution limit. This depends on the size of the de-
tector, the lens, and the distance to the target. Use the center of the spot tool
as a guide to the minimum possible object size, and get closer if necessary.
Make sure to stay away from dangerous areas and live electrical components.
Be careful when holding the camera perpendicular to the target. Be observant
of reflections, especially at low emissivities—you, the camera, or the sur-
roundings may become the main source of reflection.
Select a zone of high emissivity, e.g., an area with a matte surface, to perform
a measurement.
Blank objects, i.e., those with low emissivities, may appear warm or cold in
the camera, because they mainly reflect the environment.
Avoid direct sunlight on the details that you are inspecting.
Various types of faults, e.g., those in a building's construction, may result in
the same type of thermal pattern.
Correctly analyzing an infrared image requires professional knowledge about
the application.
