Troubleshooting Tips
If help is needed during the installation process, contact the local FLIR representative, send an email
to [email protected], or call 888-747-3547 inside the US. The FLIR Sensors Manager software can
be downloaded from
http://support.flir.com/
. and is a good tool to have installed for troubleshooting
purposes. FLIR Systems, Inc. offers a comprehensive selection of training courses to help get the
best performance and value from the thermal imaging camera. Find out more at the FLIR training web

Image freezes momentarily
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). Every few minutes, 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.
Using FSM, it is possible to adjust the frequency of how often the FFC operation occurs. Using the
Advanced Sensor Control, it is possible to change the FFC interval or to disable the automatic FFC
entirely by setting it to Manual mode. For the best possible image, it is recommended the factory
settings are used.
No video
If the camera will not produce an image, check the video connection at the camera and at the 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 RCA 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 it is 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 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).
Performance varies with time of day
There may be differences in the way the camera performs at different times of the day, due to the
diurnal cycle of the sun. Recall that the camera produces an image based on temperature differences.
At certain times of the day, such as just before dawn, the objects in the image scene may all be
roughly the same temperature, compared to other times of the day. Compare this to imagery right
after sunset, when objects in the image may be radiating heat energy that has been absorbed during
the day due to solar loading. Greater temperature differences in the scene generally will allow the
camera to produce high-contrast imagery.
Performance may also be affected when objects in the scene are wet rather than dry, such as on a
foggy day or in the early morning when everything may be coated with dew. Under these conditions, it
