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.
•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.
