3. Rotate the lens 30° counter-
clockwise (looking at the camera
from the rear).
To keep in mind
• Adjust the focus first. When the
camera is out of focus, the
measurement is 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
detector, 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 or live electrical
components.
• Be careful when holding the camera
perpendicular to the target—you can
become a source of infrared radiation
through reflection.
• Select a zone of high emissivity, i.e.,
an area with a matte surface, to
perform a measurement.
• Blank objects, i.e. with low
emissivities, may appear warm or cold
in the camera, as they can cause
reflections.
• Avoid direct sunlight on the details that
you are inspecting.

• Various types of faults, such as 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.
