Example 1; Example 2; Manual Adjustment In Level / Span Mode - FLIR Exx series User Manual

14 Working with images
There are two different manual image adjust modes. Select the type of mode under Set-
tings > Device settings > Set up camera > Level span mode.
• Level / span: This mode allows you to manually adjust the level and span of the tem-
perature scale.
• Level / max / min: In this mode, you can manually adjust the temperature scale mini-
mum and maximum limits, simultaneously or individually.

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.
Automatic
