@Stefan-Kersting may I ask at which location you are?
-
@johann-fuehrer as mentioned earlier I am living 67 degrees north. After everything I tested now I think there is something wrong with the barometer sensor…
-
@Stefan-Kersting Looks like something is wrong.
I wonder. If you calibrate it it then changes by it self ? eg when normally being at the office ?
-
@Stefan-Kersting just to double check: your office building - is it probably pressurized by some air con?
othewise I am with Dimitrios: Something is wrong
-
Thats what I think was so weird. I auto calibrated and could after that see and follow on the display how the altitude dropped by over 20 meters when sitting in the office @Dimitrios-Kanellopoulos. As mentioned the barometer says 1004 hPa when sitting in my office 15-20 meter above sea level when the official sea level pressure here is 1029 hPa. So the math does not work…
@Egika we have no air condition here. I observed several times that the altitude changes very fast without moving and the change in air pressure isn´t that fast changing. -
@Stefan-Kersting Ok then think the pressure sensor is bad.
I suppose cleaning etc is performed right ?
-
@Dimitrios-Kanellopoulos I had the watch about 40 minutes in warm water in order to clean the sensor. Before I checked the holes, but it didn not look like their where dirty

@Stefan-Kersting said in Issues altitude diagram:
@johann-fuehrer this is the wrong forum to shine with theoretical knowledge. I have a problem with my watch and would like to get some advice or explanation what´s wrong and what I can do with that.
What I wanted to point out is, that it’s not necessary a watch problem. As your baro and altitude readings depend on your actual position on earth, the GPS altitude reading error based on that your location location (https://eos-gnss.com/elevation-for-beginners) and negligible the temperature, your reading might be unsatisfying but correct (on a GPS point of view but not on a map point of view). Sorry for the confusion and the “shine”, but when using a GPS device the flaws should be known as well, especially when you put your life in the hands of the data you read. But I’ll shut up now.

@Stefan-Kersting can you flush with pressure under the tap after soaking it?
Also use a baby toothbrush to clean the component gently.Try this 3 times :
10mins soak -> Flush under the tap -> clean with baby toothbrush
After that let it dry, blow some air for the water to get out the pressure sensor holes.
Then please test. Static the altitude should not change

@Dimitrios-Kanellopoulos thanks! gonna try this.
