• Auto or Manual Range (default is Auto) – Gives you
control over the lowest and highest temperature.
• Span (default is the Imager’s Range, or widest
temperature range from lowest to highest temperature
that the Imager can detect). A custom span setting lets
you narrow the range of temperatures. This reveals
small temperature variations as different colors. The
Span setting is like reducing the scale in a graph,
magnifying small variations for easier viewing.
• Level (no default) – Level is always the center point of
the Span or Range.
• Palette (default is “IRON”) – The Palette is the color
scheme for the display and saved thermal images.

Optimizing Thermal Images
Once you become familiar with basic operation, you’re
ready to discover the image enhancement and refinement
you can achieve using custom settings. The custom setting
that has the most impact on temperature reading accuracy
is Emissivity. If you select only one custom setting, this is
the one to change. All the custom settings that affect the
accuracy of your data are:
•
Emissivity (default is 0.95 - rubber, asphalt, concrete,
black electrical tape) – Adjusts the Imager to
compensate for different target surface materials.
