Setting Temperature Level and Span |
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.
Note
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.
•If you highlight the center point (level) temperature, use the up/down mouse action to move the center point temperature accordingly, while keeping the range (span) constant. Use the left/right mouse action to change the palette range (span), leaving the center point (level) unchanged.
2.Tap the TRIGGER button to select to accept setting change and return to scan target mode.
