5  Quick start guide

Follow this procedure:

5.1  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 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 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 surroundings 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.
