Quick Start Guide
Follow this procedure to get started right away:
1. Charge the battery for 4 hours.
2. Insert the battery into the camera.
3. Insert an SD memory card into the card slot (C3) at the bottom of the camera.
4. Push the On/Off button (A10) to turn on the camera. Allow 45 seconds for the
start-up sequence.
5. Aim the camera toward your target of interest.
6. Push the Preview/Save button (B2) halfway down to autofocus the camera.
7. Push the Preview/Save button (B2) fully down to save an image.
8. To move the image to a computer, do one of the following:
Remove the SD memory card (C3) and insert it into a card reader connected
to a computer.
Connect a computer to the camera using a USB Mini-B cable (C2).
9. Move the image from the card or camera using a drag-and-drop operation.
To keep in mind
Adjust the focus first. When the camera is out of focus, the measurement is wrong.
By default, the camera adapts 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.
