Power button
The power button (1 in Figure 5.3
Camera back panel description.
, page 11) is located
behind the touch screen LCD. Open the touch screen LCD to its maximum extension to
access the button.
Note
Keep the LCD screen opened or detach it when the camera is being operated to
prevent the external cooling vent from being blocked.
A short press on the power button starts the camera.
To turn off the camera:
• A short press on the power button starts the camera shutdown procedure. The cam-
era is switched off a few seconds later.
• A long press on the power button forces the camera to turn off immediately, bypassing
the shutdown procedure.

Camera boot-up and cooling down
When the camera is turned on, its Stirling cooler starts first. Stirling coolers produce
noise. A high volume of noise is normal for advanced cooled thermal cameras.
The camera requires up to 7 minutes to reach the detector temperature of 80 K. In paral-
lel, the camera performs a built-in test of its components and initializes the internal soft-
ware and interfaces.
The camera is ready to use when all the status LEDs on the back panel are green (2 in
Figure 5.3
Camera back panel description.
, page 11).

Adjusting the field of view
Once the camera is installed and operating, its field of view is adjusted to suit the thermal
scene being imaged. This adjustment is done by selecting a suitable lens for the desired
field of view, and then fine tuning the camera position to the scene.
Use of the LCD screen is helpful during this procedure.
6.3.1
LCD screen
The FLIR X6520sc includes a detachable touch screen LCD that provides instant ther-
mal image feedback. The LCD screen also provides camera information, adjustment
controls, and ResearchIR Max acquisition control.
In the LCD screen examples below, the camera measurement configuration and temper-
ature range have been adapted to the thermal scene. If the camera is not correctly set up
for the scene, the image can become saturated.
The temperature range of the camera can be automatically adjusted using the auto-ex-
posure button on the touch screen. For more information, see section 8.2.2
If the thermal scene does not match the configuration measurement (i.e., the spectral fil-
ter on the filter wheel), it is necessary to select the correct configuration measurement in
ResearchIR Max. For more information, see section 6.4.4
