11.4.7 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.
11.4.7.1 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.
Every 30 min approximately every 30 minutes.
Every 60 min approximately every 60 minutes.
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.
11.4.7.2 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-
ress ... is temporarily displayed under the image on the screen
11.4.8 Using the camera lamp
The camera is equipped with a lamp. To turn the lamp on or off, follow this procedure:
1. On the toolbar and in the Calibration tools section, click Light.
2. Click ON or OFF.
11.4.9 Adjusting the temperature scale
The camera continuously auto-adjusts the image for the best image brightness and con-
trast. In some situations, manual adjustments can make it easier to analyze details in the
image. For example, by manually changing the maximum and/or minimum temperature
levels to levels near a certain object in the image, you can study temperature variations
in the object.
