Altimeter recordings while running
-
@Dimitrios-Kanellopoulos but 120 meters off is ok? I wouldnt be happy with that…
-
@Iceman1 yes
-
@Dimitrios-Kanellopoulos yes, but watch did not corrected deviation of in altitude of 120m. Today already delivered watch to support for check

Hello, today i have tried this trick. instead of 45m i have manually entered 160meters, but watch did not corrected anything:
If I remember correctly fusedalti doesn’t correct your altitude when you manually changed it before the activity. Read it somewhere on this forum.

I tested it several times on the Vertical. 15 minutes before the activity I changed the altitude to a complete false value and the Vertical calibrated within the first minute to the correct altitude.
May be a manual calibration immediately before the start of an activity is a problem.
-
@surfboomerang I think that has changed now and it will work.
-
@pilleus correction to false altitude was done maybe 10 hours or more before the activity…

Automatic alti-baro profile,
Interesting observation on my Suunto Race. I live by the coast which is affected by high winds. I also live in an apartment on the 8th floor and unfortunately happen to be in a direction that when it is windy my apartment becomes a wind tunnel. I noticed quite a big change in altitude of 25m from 109m down to 84m, which is close to accurate altitude, all just from the change in air pressure.
In the manual it states, " If you are at a constant altitude (less than 5 meters of vertical movement within 12 minutes), your watch interprets air pressure changes as weather changes and adjusts the barometer graph accordingly."
However in the linked video below the watch thinks I’m changing altitude.

@Brad_Olwin Hello,
so while my Vertical being checked, they gave me Race as a replacement. i never thought i might like it so much. it is very fun device, because i always run in the dark and that screen is just pleasing. i have done two runs so far. first one had extraordinary altimeter performance (day before run i have adjusted altitude manually to correct one), but for today’s run i have set altitude off again by +115m and watch did not correct it either (last two runs in the table):
-
@Tadas-Linge hard for me to interpret your table, but from the trace on the initial post on your Vertical there are a lot of small spikes in the trace. It would be helpful to see the trace for the Race as well. I do not know what the actual altitude is for your run. Below is an example from me for yesterday, a SkiMo with my 9PeakPro underneath all clothing on my wrist and my Vertical outside my jacket exposed to snow, wind etc. They both show identical profiles. 9PP/Vertical Ascent 878/890; Descent 879/877.

@Brad_Olwin Hello,
yes sure,this is the first run with manually correctly adjusted altitude:
and this is second run with manually not correctly adjusted altitude (+115m):
-
@Tadas-Linge So, I assume 48m is correct and starting at 115 is way off. What does the barometric trace look like on your watch for the time you are not exercising?
-
@Brad_Olwin Hello,
but just to be on the same page, i have entered manually wrong altitude (+115m) to see if watch will correct it.
during the whole exercise watch was showing the same altitude which is in the graph and i was waiting and waiting when will it be readjusted, but it did not happen. -

Otherwise the watch assumes you know your current altitude and accepts your manual altitude setting.
-
@Tadas-Linge looking at the graphs they are almost overlapping (execept for the offset) so it’s a mistery why FA does not (always) trigger in your case

It was true long ago, but seems no more (I read it somewhere here).
I tried this few days ago, but I didn’t offset “only” 115m but 1000m (for the same price
), and my watch was fixed during the first 10/15min of my run. -
@Tadas-Linge To me the 45m trace is not bad, but my outdoor exercises typically involve gains or losses of ~300m or more. What does the barometric trace on the watch look like for you or on a website for your area?
I see a lot of small spikes in your original and posted traces. Where do you wear the watch? Is it on top of clothing or underneath? Is it possible that the clothing or skin is pressing up against the sensor?

-
Offsetting the altitude by 60 m half an hour before training: altitude is correct in SA.
-
Offsetting the altitude by 60 m directly before training: altitude is off by 60 m in SA.
So I guess the behavior depends on the watch generation?

yep!

@Mauerwegler
Oh, i didn’t see you have a spartan
(it is what i called : “long time ago” )
