Color Palette

The Palette menu changes the false-color presentation of the infrared images
that are on the display or captured. A variety of palettes are available. Some
palettes are more suitable for specific applications and are set as required.
Grayscale Palettes offer an equal, linear presentation of colors that allow for
best presentation of detail.
The High Contrast palette offers a weighted presentation of colors. This palette
is best in situations with high thermal contrast for increased color contrast
between the high temperatures and low temperatures.
The Ironbow and Rainbow palettes offer a mixture of the High Contrast and
Grayscale palettes.

Reflected Background Temperature

The background temperature can be set between -10 °C and +100 °C.
Compensation for reflected background temperature is set in the Background
tab. Very hot objects or very cold objects can affect the apparent temperature
and measurement accuracy of the target or object of interest, especially when
surface emissivity is low. Adjustment of the reflected background temperature
can make the temperature measurement better in many situations. For more
information, see Emissivity on page 14.

Hot and Cold Markers

The hot and cold markers turn on and off. When turned on, the marker is an
indication of a hot or cold spot in the scene that may require additional
evaluation. When turned off, the user is able to concentrate on the single
measurement pixel.
