What is your watch? This looks like a watch issue, not an iOS one so I’ll move the topic to the appropriate section.
For the S9, but probably this is true for Spartans too, calibrating before actually prevents Fusedalti to work properly. I stopped calibrating at all and have much better readings compared to last year.
Also, if you have never done that, a night soak in lukewarm water helps. -
Have a Spartan ultra, but without HR sensor. I wear the watch all the time even when taking a shower isn’t that enough? When you watch shows -36 masl altitude you reccomend not to calibrate before starting a run?
-
Since learning that calibration interferes with Fusedalti, I calibrate my S9 only if I travel far away (by airplane) and don’t plan to have any activity for few days. Otherwise, even if I know it’s wrong, I rely on the watch figuring out things by itself.

@Stefan-Kersting said in Issues altitude diagram:
I wear the watch all the time even when taking a shower isn’t that enough?
In fact it isn’t, as soaking it in warm water for a while let any dust or soap residue to be removed/washed away, while showering wearing the watch can lead to the opposite result
-
Also for me looks more of a baro sensor dirty thing. Soap can condense there
2 things here also for others to know:
Let the watch soak in water, flush under the tap making sure water goes in / out the pressure sensor holes.
However and important:
Do not leave the watch in the water for many hours. The watch is protected and is waterproof but leaving anything into water for a lot of time might affect components errosion etc. That is a personal tip.
-
@Stefan-Kersting i also recommend not calibrating. FusedAlti may not activate if you manually calibrate.
-
Hello, how are you? Sorry for this question. But I don’t understand, too well, what is the calibrate option for then?
-
@Iván-Martín-Mora FusedAlti only weorks well if GPS reception is possible and at a certain quality. In deep valleys it could be not enough for proper altitude calibration. In these cases (or indoors without GPS) it is still possible to calibrate altitude manually.
-
@Brad_Olwin without calibration it looks like this. The altitude displayed on the watch before I started it was -19 meters
-
@Stefan-Kersting did you already try to clean the baro sensor?
-
@Stefan-Kersting what is the altitude you would expect ?
0 ?
-
@Dimitrios-Kanellopoulos starting at 5 masl. That is 100 percent sure altitude at home
-
@Stefan-Kersting
Android app or iOS?
With Android, there are raw data files in phone that can be imported in QS : you could see GPS altitude, and some other data that may help understand if fusedalti worked properly or not, of if GPS signal was good enough.

@Mff73 no have iOS. But it could be nice to have information about the signal quality. Maybe a azimuth Display or something like that. But I don’t know if the problem lies there
-
Did everything you guys recommend. Used Auto calibrate, manual calibrating, had the watch for half an hour in warm water. But when your supposed to start at 4 masl and finish at masl this result is absolutely unacceptable
-
-
@Stefan-Kersting It could be the sensor is faulty too, hard to say.
-
@Brad_Olwin when Auto calibrating, do you get a confirmation? I just have this screen even when outside and trying to auto calibrate
-
@Stefan-Kersting I think no on Spartans. However you can set the altitude to 1000m and check if its changed
-
@Stefan-Kersting
Never, but it say “in background” so … I never expected it
but I noticed a blink in the watch face
