UNI-T UTi120S repeating recalibration issue

[Peter78]

Hello all!

I have a problem with UNI-T thermal camera. Immediately after turning on or calibration readings are correct, then temperature slowly dropping to wrong values, then we have automatic calibration and this loop repeats endlessly. To illustrate the problem I've created video:

First of all, according to the thumbnail of the video, I see that the battery level is quite low, so maybe charging that up might do the trick. If not, try turning it off then on again or else reset it to factory settings.

Unfortunately all of those steps already failed. Factory reset is not changing anything, same for battery level.
