There will be occasions when you want to display values below or above the temperature range, especially when the image is in a high range: for example, the range is 200–1500°C and you want to see the surroundings, which are sometimes below 200°C.

In these circumstances, FLIR Tools changes the minimum and maximum in the temperature scale to the temperature range set.

If you want to see values outside this range, go to Options > View, and select Use entire-scale setting on auto adjust image.
