Automatic Level and Span

When you enable the automatic level and span function, the color palette
temperatures are regularly updated to the current maximum and minimum
temperatures in the image at a time interval you set (from 1/4 second to 10
seconds).
To enable automatic adjustments of the color palette temperature span:
1. Tap F.
2. Use the mouse controller to position the pointer over Image Settings on
the popup menu and tap E.
3. Position the pointer over the Palette tab and tap E.
4. Position the pointer over the Adjustment Interval down arrow, tap E.
5. Use the mouse controller to scroll to the interval you want, and tap E.
Select Manual, rather than an interval, to enable the Manual function.
6. Tap to accept setting change and return to scan target mode.

Arbitrary Fixed Temperature Level and Span

This feature allows you to adjust the level and span "on the fly," while
scanning targets of special interest and creating high contrast in the
temperature ranges of those targets.
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 set the level and span to an arbitrary fixed temperature span:
1. With the color palette showing on the display screen, highlight any one of
the three palette temperature values (minimum, maximum, center point).
If you highlight the minimum or maximum temperature, use the
up/down mouse action to change palette range (span). The center
point (level) temperature also changes accordingly.
