I haven't played with it, but it's my understanding that when the thermal image is overlayed on top of the visual image they can come out of alignment. That setting fixes it.
@@74357175 This is a common problem for thermal cameras that have also a visible camera (and a software to overlap the two images togheter)..... The two cameras are placed closer as possible to each other, but of course, cannot be aligned perfectly (so the point of view of is slightly different between each other). At long distances, this effect is negligible, but at short distance this effect starts to become annoying: the alignment set is used to make sure that the two images are aligned together. BTW... at very short range (i.e. if you need to pin point a failed component in a PC board) the alignment became almost impossible (so, at very short range is better to avoid the use of the fusion feature). Concerning the emissivity.... each material have a specific value of emissivity (tables are plenty available on internet) and you must adjust the settings properly in order to have the correct temperature measurement. If the emissivity is too low, some other factors came into play to reduce the accuracy of the camera, in these cases, a special sticker (called emissivity sticker) may help.... just stick one of these on the surface you need to measure and you instantly have a calibrated spot. (another trick is apply some candle sooth to the surface.... 0,95 emissivity sample for free)
Has anyone figured out what the image "Alignment" settings (0.5 -- 3.0) mean?

@@3rdpig ooh, like calibration?
It's just that I've varied that setting and don't see the effect...
