3.11 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—you may be-
come 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, as 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.
