Temperature range
The camera is calibrated for different temperature ranges. For accurate temperature
measurements, you must select a temperature range that matches the expected temper-
ature of the object you are inspecting.
To change the temperature range, select
Settings
>
Camera temperature range
. This dis-
plays a menu where you can select the temperature range.

Thermal image adjustment
8.4.1
General
Thermal image adjustment, or thermal tuning, means adjusting the temperature scale of
a thermal image, in order to maximize the brightness and contrast in the image.
In automatic mode, the camera continuously adjusts the image for the best presentation.
The camera selects the coldest and warmest temperatures in the image as the lower
and upper limits of the temperature scale. The colors are then distributed over that tem-
perature interval (histogram color distribution).
In manual mode, you can adjust the temperature scale to values close to the temperature
of a specific object in the image. The colors are distributed evenly from the lowest to the
highest temperature (linear color distribution).
8.4.1.1
When to use manual mode
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.
