10.4.6 Auto-adjust region
By using the Auto-adjust region feature it is possible to select an area of the image, and
then have the colorization of the image adjusted based on the temperatures within that
selected area.
To configure an auto-adjust region, follow this procedure:
1. On the toolbar and in the Data presentation modes section, click Auto-adjust region.
2. In the image, click and then draw a region of a desired size.
3. To move the region, click and hold the region label in the image, and then move it into

4. To resize the region, click and hold one of the corners of the region in the image, and
then move it to the desired size and shape.
5. To remove the region, click X in the region label.
10.4.7 Calibrating the camera
The calibration of the camera is performed as a non-uniformity correction (NUC). A NUC
is an image correction carried out by the camera software to compensate for different
sensitivities of detector elements and other optical and geometrical disturbances

.
Calibration is needed whenever the output image becomes spatially noisy. This may, for
example, happen when the ambient temperature changes. The calibration can be carried
out automatically with different selectable intervals. It is also possible to perform a cali-
bration manually.
10.4.7.1 Automatic calibration
To set the automatic calibration, follow this procedure:
1. On the toolbar and in the Calibration tools section, click Calibration. This displays a
list of calibration options.
2. Click one of the options:
Option Calibration is automatically carried out:
Auto when needed.
Every 10 min approximately every 10 minutes, or when needed.
Every 30 min approximately every 30 minutes, or when needed.
Every 60 min approximately every 60 minutes, or when needed.
Every [type your value] at any set interval.
OFF never (automatic calibration disabled).
3. While the automatic calibration is in progress, the Notification text Calibration in prog-
ress ... is temporarily displayed under the live image.
10.4.7.2 Manual calibration
To perform a manual calibration, follow this procedure:
1. On the toolbar and in the Calibration tools section, click Calibration. This displays a
list of calibration options.
2. Click Calibrate now.
3. While the manual calibration is in progress, the Notification text Calibration in prog-
