Suunto 7 Altitude Issues

@aleksander-h said in Suunto 7 Altitude Issues:
Shouldn’t a blocked baro hole be detected when in for service?
fully agree! if you report weird alti observations, service should look into that, too!
the general advice is to soak the watch in a glass of water over night and use a very soft (baby)toothbrush.
my S9B also went nuts some time ago and I did the soaking and sensorbrushing. after that it was fine again

@aleksander-h Sounds very much like my issue. The altimeter was fine the first six months then getting gradually worse to the point where it would record an ascent when I was in fact moving downhill. It went from recording a detailed altitude profile with small ups and downs to a all smoothened out profile with a max altitude that could be a doubling of the real altitude. Service in Finland did a lab test to check the sensor and said there was no problem with the sensor so I did more tests/runs/walks to confirm the issue and sent it back to Suunto, this time HSH Sport in CZ. I’m looking forward to their conclusion.

@freeheeler I gave it a quick brush this morning. Did another a fridge test now. The baro app I found shows within 1 m of when I put it into the fridge. Wondering if maybe this helped. Of course, no idea if the app is only using the barometer, but I assume so as the altitude reading seems to be in real-time. It’s jumping up and down constantly on the decimal digits, so it seems to be using pressure. Stays within 1 m on the reading which is promising.
I’ll try and find time for a walk later today.

like @freeheeler said, i would do the best sensor cleaning you can (in warm water long time, rince under tap, and do it a couple of time to be really sure). Make sure water comes into the holes, and go out after rincing (an old advice from masters of rincing
: gently tap the watch on a towel, facing holes to the towel : it may help water going out).
And if nothing change, Suunto support again. -

Can the S7 handle being submerged in water 9vernight without risk?
-
@aleksander-h
yes, it should survive it… just don’t press any buttons when submerged
-
@freeheeler cleaned with unused toothbrush. Here is a new 1 hour balcony test.
Not sure why it went up, but at least the suunto app says 0 m up and down.
-
@aleksander-h Why are you doing a stationary test?

@bulkan because I can’t leave the office

10 m in 1 hour seems not to unreasonable to me. I’ll have to go for a few walks and runs, but I’m guessing things are actually good now! Which is an immense relief
-
@aleksander-h
looks better, indeed -
@mff73 thinking about it. 10 m increase in altitude is more or less equal to the offsett I see on my SSU (I often get roughly 10 more ascent then descent despite starting and stopping at the same place). So it seems fixed!
Now all I have to do is spend the rest of the day tapping the update screen…
-
Well. After the update I did a 15 min short lunch walk to get out of the house/office. I’m happy to say the elevation graph looked beautiful! No wonky lines, ascent where I expect it to be, descent where I expect it to be!
Thanks for all the help forum posters!

@aleksander-h If the exercises have the exact same time the app may filter one out. Just make sure you start one 20-30sec before or after they other, then they will sync fine. I have had this happen as well.

I started them both at exactly the same time, and ended both at exactly the same time. So it is definitely no surprise if the Suunto App thought “nope, don’t need that one”.
Thanks for the tip. Hopefully though, my SSU can go back to being a reserve watch now

Welcome (on behalf of other helpers also
) You are now officially knowledge repository of ascent/altitude issues and official next helper

@mff73 I look forward to telling people they need to stick a soft toothbrush carefully into the baro hole
.I’ve picked up a few cool tricks along the way. Extracting the zip file from the android app and uploading the samples.json file to qs gave me all sorts of cool stats I didn’t know I could view!

Suunto takes care that we grow with our challenges

@brad_olwin is this new?
so far I have often recorded activities with both S7 and S9 and always have had duplicates in the app.
Now on Sunday it was the first time that I ended up with only 1 activity in SA after syncing the two watches.t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Granite Blue Titanium, S9PP Titanium Sand, Vertical All Black, Race Titanium Charcoal, Race S All Black, Race S Titanium Canary

Hi all,
I have the same issue with altimeter measurement jumping high and low of about 12 meters. I tested the watch with Altimeter wear os app and the readings confirm the continuous wrong measurement.
Moreover I noticed that gently squeezing the bezel or the back of the watch I systematically can change the altitude up and down.
I think that there is a hardware problem…
Someone can confirm?
