Setting Temperature Level and Span

The color palette is available to help you visualize the relation between
temperature and color. Setting the span to the narrowest range possible
provides the highest quality images.
When using the manual or automatic level and span function, if the center box
function is enabled, the temperature updates are done based on the
temperatures in the box, not the entire image. Using this feature, you can
exclude an area in the image that is very hot or very cold but of little interest.

Manual Level and Span

When you press the LEVEL & SPAN button, your camera takes the current
coldest and hottest temperatures from the scene and sets the palette range
minimum and maximum limits so that everything in the scene is scaled
between the minimum and maximum temperature if the target temperatures are
within the camera's currently selected calibration temperature range. If the
target temperatures are outside the currently selected calibration temperature
range, the target is displayed in the saturation color for the current color palette
(see Using Palette Saturation Colors later in this chapter).
Be sure the temperature calibration range is set properly. See Setting
the Temperature Calibration Range in Chapter 6). If you have enabled
the center box marker (see Chapter 4), the color palette is adjusted
based on the minimum and maximum temperatures in the center box,
not those in the rest of the image.
To manually adjust the color palette temperature span, tap G as needed. Be
sure the "Manual" function is enabled (refer to the procedure under Automatic
Level and Span).
