What is the span?

• A. Differences between Temperatures
• B. Range of time
• C. Color palette range
• D. Differences between Temperatures

Answer: (B)

Span means the duration or time interval covered. In thermography work, the span refers to how long a recording or observation lasts—from the start time to the end time. It’s about the range of time, not how much the temperature changes or what colors are shown on the image. Differences between temperatures describes delta T, while the color palette range describes the display scale. So the range of time best matches what span denotes.
