Basic Operation
2.1
If you need help during the installation process, contact your local FLIR representative or, call 877-
773-3547 inside the US. FLIR Systems, Inc. offers a comprehensive selection of training courses to
help you to get the best performance and value from your thermal imaging camera. Find out more at
the FLIR training web page:

2.1.1
By design, the camera image will freeze momentarily on a periodic basis during the Flat Field
Correction (FFC) cycle (also known as Non-Uniformity Correction or NUC). Periodically the image will
momentarily freeze for a fraction of a second while the camera performs a flat field correction. A
shutter activates inside the camera and provides a target of uniform temperature, allowing the camera
to correct for ambient temperature changes and provide the best possible image. Just prior to the
FFC, a small green square will appear in the corner of the screen.
2.1.2
If the camera will not produce an image, check the video connection at the camera and at your
display. If the connectors appear to be properly connected but the camera still does not produce an
image, ensure that power has been properly applied to the camera and the circuit breaker is set
properly. If a fuse was used, be sure the fuse is not blown. If the video cabling is suspected as a
possible source of the problem, plug a monitor into the BNC connection inside the camera and
determine if it produces an image.
When the camera is powered on, it will do a NUC operation shortly after startup. If you are uncertain if
the camera is receiving power, it may be useful to listen to the camera to hear if the click-click of the
shutter mechanism can be heard. It may be only be possible to perform this test when the camera is
on a work bench rather than in its installed position.
If the camera still does not produce an image, contact the FLIR dealer or reseller who provided the
camera, or contact FLIR directly (contact information is provided on the rear cover of this manual).
2.1.3
A noisy image is usually attributed to a cable problem (too long or inferior quality) or the cable is
picking up electromagnetic interference (EMI) from another device. Although coax cable has built-in
losses, the longer the cable is (or the smaller the wire gauge/thickness), the more severe the losses
become; and the higher the signal frequency, the more pronounced the losses. Unfortunately this is
one of the most common and unnecessary problems that plagues video systems in general.
Cable characteristics are determined by a number of factors (core material, dielectric material and
shield construction, among others) and must be carefully matched to the specific application.
Moreover, the transmission characteristics of the cable will be influenced by the physical environment
through which the cable is run and the method of installation. Use only high quality cable and ensure
the cable is suitable to the marine environment.
