Dear DJI and other M2EA users.
This past weekend and the weekend before I was flying my M2EA in cold winter temperatures. First time it was twenty degrees C below freezing (-20C) ambient temperature and this weekend it was a more moderate 3 degrees C above freezing (3C) and windy.
At both occasions I noticed that the temperature readings from the thermal sensor was WAY off to the low end. Surfaces that should read around 0C is reported to be -10C or even lower. Pointing the camera at the sky (in nighttime) yields a reading down to minus 21.1C (-21.1C).

When trying the camera in room temperature it seems to report correct values like ~36 degrees C for a human face. Trying to use the FFC function seems to have no effect - but the problem is that I can't find any procedures to accomplish this in the manual. How do I calibrate my sensor for cold weather readings?
