14 Working with images
temperature levels have been changed to temperature levels near the isolator. This
makes it easier to analyze the temperature variations in the isolator.

14.5.4 Procedure

Follow this procedure:
1. In live mode, push the button
2. To change the temperature scale minimum and maximum limits simultaneously,
move the joystick up/down.
3. To change the temperature scale minimum or maximum limit, do the following:
• Move the joystick left/right to select (highlight) the maximum or minimum
temperature.
• Move the joystick up/down to change the value of the highlighted temperature.
4. (Optional step). In preview/edit mode, push the button
adjust sequence.

14.6 Performing a non-uniformity correction (NUC)

14.6.1 What is a non-uniformity correction?

A non-uniformity correction is an image correction carried out by the camera software to
compensate for different sensitivities of detector elements and other optical and geomet-
rical disturbances 1 .

14.6.2 When to perform a non-uniformity correction?

The non-uniformity correction process should be carried out whenever the output image
becomes spatially noisy. The output can become spatially noisy when the ambient tem-
perature changes (such as from day to night operation, and vice versa).
14.6.3 Procedure
To perform a non-uniformity correction, push and hold the Image archive button
more than 2 seconds.

14.7 Changing the temperature range

14.7.1 General

You must change the temperature range according to the expected temperature of the
object you are inspecting.
14.7.2 Procedure
Follow this procedure:
1. Push the joystick to display the menu system.
