NO GOOD DATA ASCENT (AND DESCENT)
-
@matteo-zambenedetti yes, during the first 15 minutes.

Good morning everyone,
I return to the subject to post some files to better explain my problem.
First of all, I don’t understand why SUUNTO does not provide software for pc but only apps for android (or mac) …
So, this is the screenshot of my hike according to the data of my 9 Baro and the app Suunto
in my phoneASCENT 3168MT!!! UNREALISTIC!!!
and this is the screenshot of the same track but downloaded on Openrunner software
ASCENT 1368MT!!! REALISTIC!!!
and this is the track.gpssuuntoapp-Hiking-2022-06-19T00-32-03Z-track.gpx
can anyone help me to understand and solve the problem?
what is the exact procedure to follow before starting a hike or a bike ride?I apologize if I can’t answer right away but I’m working and I don’t have much time
-
@matteo-zambenedetti what is the problem?
If you start higher than 1800m, and climb till 3200…at least roughly: 3200-1800=1400.
You have some other climbs on the graph, but also, you start higher than1800, so I can’t understand where is the issue. -
@matteo-zambenedetti Can you also share the ascent graph in the Suunto phone app?
-
the problem that openrunnere says I climbed 1368 meters (correct) while summarized says that I climbed 3168 meters (wrong)
-
the .gps track that posted before cannot be opened?
-
@matteo-zambenedetti I understand that the watch says the same than the Suunto app, am I right?
I want to see if the ascent graph from the watch has spikes, so it means that for some reason the baro sensor has been blocked (skin, jacket, wind,…) and for that reason you have higher ascent than expected.
-
@cosme-costa I understand what you mean. I therefore report the profile of my excursion: you will notice that there are no peaks.
However, if there were, Openrunner would have had to show me the same rise as Suunto. My problem is why was my 9 baro wrong?
-
@matteo-zambenedetti
because of several small spikes that I can already see without zooming in… maybe the other platform filters it by default? Strava filters by request -
@freeheeler Does your 9b the same?
-
@matteo-zambenedetti
yes, when the wrist strap is too tight and baro holes seal on wet skin, it catches wind gusts or wet garment is covering the baro holes…
check with your next activity and a bit looser wrist strap
-
@freeheeler Ok thanks, I will try this week-end.
-
@matteo-zambenedetti As @freeheeler says, you can see the small spikes that are adding ascent. The shape of the profile is quite correct as it is the min and max height, but during the activity it has been adding small ascent. And as it has been said probably because the baro sensor has been blocked.
I only have had this situation once and it was because it was raining and I was wearing the watch over my membrane jacket and the jacket blocked intermittently the baro sensor.
BTW, in which hand were you wearing the watch? Did you use poles? I ask this because this could increase the chances of blocking the sensor.
-
I’ve the same problem here (Suunto 9 baro). Most times when i start the descent, it adds more and more meters to ascent (real ascent was about 1100 m and real descent was 1900 m; at the end of the activity I had 3300 m (!)
Weather was stable; not much wind, barometer was free… but anyways… the watch is made for outdoor sports; or not?
The climbing activity is complete useless. After a few minutes there are unrealistic ascents and descents of several 100 meters.
-
@Oliver-Zamberger
please share your alti graph -
As you can see it the issues starts when descending (it was yesterday). At the end I it added about 200 m more in ascent (and descent too).
Ascent/Descent in reality: 635 m
Ascent/Descent from the watch: 850 mThe longer the activity is, the more the deviation goes up
And here the climbing graph (completly useless):
-
@Oliver-Zamberger From what I see in the graphs, for some reason you or something are blocking the baro holes, so you have a pumping effect. Maybe your skin, maybe wind, maybe some of your gear… It could be that the sensor is faulty as well but I would try to analyze how was your activity and detect what could have blocked the baro sensor (the very few times that I had this I could identify the causes to avoid it in the future).
-
@cosme-costa Actually there was nothing blocking the baro holes (no shirt or something else). It just could be the skin; but movements are natural in activity. It’s diffcult to not use the hand while climbing…So maybe the baro is placed on a wrong place on the watch; maybe it should be placed on top side of the watch?
on the first graph I didn’t use the hands much; just walked downwards and the hands were all free
-
@Oliver-Zamberger Position of the sensor is really important but I guess not all the positions are ideal. I mean for the S9B, if you wear it in the left hand sensor is less exposed but if you wear it on the right it is more exposed for wind and hand movement. All the position have its downsizes.
I do not know how your arm is or how tight you wear your watch, all this could affect, in my case I have tinny arms and it is impossible to me to block the sensor wearing the watch in the left arm. I am extremely happy with the accuracy and reliability of the ascent/descent values.
In your case, I don’t think the sensor is faulty because the shape of the profile is OK and the values in a fixed point seem also correct. When the sensor has issues the pressure values change all the time.
Could be that your sensor is partially blocked ? I mean, if some of the sensor holes have dirt it is more easy to block. In my case I always rinse the watch with tap water after my activities and I never shower with it to be sure that sweat/dirt/soap don’t block the tinny holes.
-
@cosme-costa I wear the watch on the left. not too tight (as recommended). So naturally if i use/move my left hand up (climbing for example), it may be, that the baro is covered shortly. So I ask myself, if there’s a climbing activity on the watch, it was made for this too and the hand movements shouldn’t be a problem at all… more less at hiking.
The problems started several months ago. After some time it was better again. But during the last weeks it’s really bad again.
