So, according to this negative point it is much better:
The display contrast can be adjusted well, sadly lacking the already mentioned backlighting (as Zuschaltmöglichkeit). A direct comparison to outdoor sensor indoor sensor with temperature and humidity showed exactly the same values. Good thing.
I also like the possibility of correction of air pressure and humidity. However, to me the sense of the permanent reconstruction of the barometer graph is completely unclear annoys me the more. The "speed" of the symbol Forecast can fortunately be affected. In fact, I think almost the Barometer Forecast for better than this DCF - or other radio services in other weather stations offer it for my place.
The outdoor sensor is securely achieved over a distance of 8 meters. However, I trust this is not so pretty as to its moisture defense. Actually, the humidity sensor would have to be separated from the inner life. Here, however, must provide an opening for this sensor remain and are the moisture the way into the interior more than necessary free, well ...
The display of the moon phases is often accepted as a small gimmick.
Positive also the operating instructions should be mentioned that it adequately explained the exact functions. Pity you can see not even de Month / Year. This is only possible in the SET mode.
