Ascent/descent completly wrong

[Oliver_Z]

@surfboomerang Sure, I know what you mean… Every ascent and descent will be summed up. But like in my case it’s really too much

[Dimitrios Kanellopoulos]

@oliver-zamberger looks like the barometer had water in

[Oliver_Z]

@dimitrios-kanellopoulos that wasn’t a Problem since the läßt Update. This is an expensive multisport watch and some sweat shouldn’t influence the Barometer.

[sartoric]

@oliver-zamberger
Well … that’s hard due to physical limitation

It’s not easy to fill it with water, but it can happen

[Oliver_Z]

@sartoric and today it happened again. The Barometer Was always free from sweat and not covered with anything. Descending but then suddenly the watch added about 20 m to ascend. So after the hike more than 100 m altitude (ascent/descent) are wrong. And Not any answer from the Support. That’s really annoying!

@oliver-zamberger did you try cleaning the baro hole? Warm water, a soft brush.

@oliver-zamberger
and a link to the activity to check the graph, please… otherwise it’s just wild guessing for us

[Oliver_Z]

@freeheeler I’m thankful for any solutions/help

So here is the link

@oliver-zamberger Was the wach protected by a sleeve? In other words, could wind be a factor in this situation?

[Brad_Olwin]

@oliver-zamberger Here is an example from this weekend. I was wearing an S9P on my left wrist and an S9baroTi model on my right wrist. I was carrying a handheld water bottle. On my right wrist by carrying the bottle my skin was blocking the baro hole on the S9bTi. Not the jagged altitude profile AND note the altitude is 2-fold off. There are two readings for the baro as I stopped the watch a few minutes into the run as it did not connect to the smartsensor.

@surfboomerang the watch wasn’t covered by anything. So the baro sensor was always free. Also there wasn’t really any Wind… But if Wind influences the Barometer this much to deliver wrong data, why it ever integrated into the watch

Is there any possibility to deactivate the Barometer?

[Oliver_Z]

@brad_olwin i can See. It’s totally clear, that the the altitude can’t be 100% correct. But it isn’t ok, when it’s several 100 m incorrect.

And this appears to Happen most when ascending

[surfboomerang]

@oliver-zamberger Wind does have an effect on pressure and altitude, but I don’t know to what extent.

This is data from a random windsurf session on flat water:

In the old Movescount days there was an option to select how pressure changes should be interpreted by the watch, but that option has been removed in SA unfortunately.

[Brad_Olwin]

@oliver-zamberger This is the primary reason that incorrect altitude gain happens, I have had this happen due to skin (as in the example I posted) and because of wind. It is something you can learn to avoid. If you look at the profile in my post, it did not happen on the descent. I noticed the wrong ascent, knew what was causing this and kept the water bottle in my left hand on the descent.

I would argue that your incorrect data are likely due to similar issues, once you know what they are you can typically prevent it from happening.

[Oliver_Z]

@brad_olwin I ask myself: if the watch reacts this much sensitive on sweat, Wind, water etc… IT shouldn’t be used for outdoor Sports what it was made for

@oliver-zamberger said in Ascent/descent completly wrong:

I think that your self question is a little bit biased. @Brad_Olwin and others are posting the possible causes of your issue, and it is not brand dependant, it is technology dependant. That you have had a problem, doesn’t mean that the problem is general. I never had had this issue, nor my friends using the same watch, in general S9B tend to underestimate the ascent.

BTW this watch is definitively an outdoors watch, you only need to check all the professional athletes using it.

As you have said in your previous post you didn’t have these issues before, so something have triggered it, a new way of wearing the watch, some holes of the sensor covered or blocked, using poles…If I were you I would start cleaning the baro sensor (warm water and a very soft toothbrush), then a softreset, if this doesn’t work then a reinstallation of the firmware and if eventually still doesn’t works I would contact support, the sensor can be broken too.

[Brad_Olwin]

@oliver-zamberger I will add to @cosmecosta, who said it perfectly. My issue happened only because I was wearing the watch on my right wrist and had a water bottle in that hand. This has not happened when wearing on the left wrist for me. In total, I run 5-6 days per week all year. I have had this issue maybe 3-4 times since I owned the watch in 3 years.

[isazi]

@brad_olwin it happened to me twice in 2 years, and it was in days with gale strong winds. I could have avoided the issue by just wearing the watch under the jacket, but I didn’t

[Pavlas]

I had the same problem on the bike today. I used GPS+Glonass after a long time. But it’s true that I was wearing the watch on my right hand (to tan my left hand )

@brad_olwin
uh, this info needs to be censored
regarding sensor hole coverage I fully agree, I happen to see that frequently during workouts. My luck, very very rarely when MTB, skiing or skitouring
but I have never seen a wind effect on the sensor and I went right into a hail storm with my MTB the other day. Maybe the sensor holes orientation in relation to the wind direction is crucial.
