(histogram color distribution). The temperature scale to the right of the screen shows the
upper and lower temperatures of the current span.
In manual mode, you can adjust the temperature scale to values close to the temperature
of a specific object in the image. This will make it possible to detect anomalies and small-
er temperature differences in the part of the image of interest. In manual mode, the col-
ors are distributed evenly from the lowest to the highest temperature (linear color
distribution). This is indicated by lines on the temperature scale.
There are two different settings for the manual adjustment mode:
Level, Span: With this setting, you can manually adjust the level and span.
Level, Max, Min: With this setting, you can manually adjust the level. You can also
change the upper and lower temperatures individually.
Select the type of manual image adjustment mode under
(Settings) > Device set-
tings > User interface options > Manual adjustment mode.
When manual image adjustment mode is active, the status icon
is displayed.
In live mode, select

In preview/edit mode, manual image adjustment mode is active.
Note You can also assign image adjustment functions to the programmable button. For
more information, see section 10.12 Assigning functions to the programmable button,
page 34.
Switch between auto and manual: Allows you to switch between the automatic and
manual image adjustment modes.
Auto adjust the manual temperature scale: Allows you to perform an automatic adjust-
ment of the image while remaining in manual image adjustment mode.
13.3.2 Example 1
Here are two infrared images of a building. In the left image, which is auto-adjusted, the
large temperature span between the clear sky and the heated building makes a correct
analysis difficult. You can analyze the building in more detail if you change the tempera-
ture scale to values close to the temperature of the building.

13.3.3 Example 2
Here are two infrared images of an isolator in a power line. To make it easier to analyze
the temperature variations in the isolator, the temperature scale in the right image has
been changed to values close to the temperature of the isolator.
