Fixing the Scale
The colour distribution in the thermal image is adjusted automatically but can be fixed by pressing the right-hand function button (7). This enables a comparison to be made between thermal images taken under different temperature conditions (e.g. when checking several rooms for thermal bridges). It also allows an extremely cold or hot object to be hidden in the thermal image. This object would otherwise distort the image (e.g. a radiator as a hot object when searching for thermal bridges).
To switch the scale back to automatic, press the right-hand function button (7) again. The temperatures are now dynamic again and adapt to the measured minimum and maximum values.
