The heat map report first looks at the temperature scale to know the temperature range of the image, and then looks at the emissivity value to know whether the data is credible.

Then look at the image content, the highest temperature? , the temperature of key components? What is the temperature distribution trend? ,

Analysis method:

Absolute temperature difference-how many degrees higher than the ambient temperature?

Relative temperature difference-compare the same position of the same kind and find out the abnormal position.
