Problema altimeter
-
Hello good I have problems with my watch that every three times I have to adjust the altimeter and has not yet done 1 year will have warranty

@marcos Did you use it starting an exercise or just as a display on the watch?
If you start an exercise the altimeter will calibrate itself during the first 10 minutes or so.
Without starting an exercise you have to calibrate it manually - that would be normal behaviour -
hello.
I am also experiencing “big” altimeter changes (values changes from 490m - after calibration with the GPS . and then drops at 390m if I stay at the same altitude over 30 mins, without pressure changes - still 1021 hPa).
I also noticed that the leevation gain during my workout has doubled for the same route, I believe since abou a month or two. Usually it would be 100m elevation gain and now it’s to 200m.
As shown on the screenshot, there is a drop in the middle (from 551m to 417m, gray shaded curve) ; I took a break (auto pause on) and did not go high or down.
I guess it’s the auto calibraiton with FusefdAlti that does its job after a few minutes ?
But why the fluctuation when I stay at home jus after re-calibrating ?any idea about the reason for this stranfge beahvior ?
I am using the S9PP with FW 2.37.48
I checked the forum about this issue but could not find similar cases.
thanks
Florian -
some pictures to illustrate the issue i am having (the pressure is correct, I checked the local weather app)
the trend of pressure is overnight, so I slept in my bed, whs is the altitude doing these spikes ?
Issues I am observing with workout are:
Elevation gain is too high.
Ascent and descent do not match anymore, 20% difference instead of a few percent before the issue started.
For example, a trail run with 650 m ascend and 540 descent (it should match since it’s a loop) is corrected by Strava at 380m !
