7.5 What are Isotherms and how do I select them?
Isotherms are regions within the scene having the same temperature range
which are shown in the same colour. This is best seen using either the White
Hot or Black Hot palettes. For example it can be useful to see all electrical
connections in a electrical cabinet that are within the same, user defined,
temperature range. This could very easily identify all components that may
be overheating.
