Ambit3 Peak elevation gain

[Gábor Tóth]

@mff73 said in Ambit3 Peak elevation gain:

ALLY like a baro sensor HS Search for “fridge” test , and try it, if altitude change from inside to outside …

Hi! thanks for the responses. I will give it a try, to use the automatic or the altimeter way of altitude measurement not just the barometric. if it continue to fail, i will search for an authorized service… : /

me again…did a 3 days skitour, and this time the elevation difference was huge, something like additional 600 meters per day. The peaks altitude was recorded properly, but the starting point never got fixed by fused. Also this time I was starting from a hut, so there should have been no variance (only inside/outside temperature was different). I think I will switch back to my ssswhr, cannot get such big discrepancies

PS: I did the fridge test and the variance was ok

@zzmike76
the total of 3 days is 600m off? 200m per day? Or was it 600m each day of the total ascent that was wrong? And by how much is the start altitude wrong?
Because I can see on my S9B frequently that the start alti is about 10m too low… it looks weird on the graph for roundtrips but is well within tolerance for me

[zzmike76]

@freeheeler second day : 600 meters more, third day : 500 more. Starting altitude was always 150-200 meters less

@zzmike76
do you like to share once more your recordings with us after the upload to QS?
I know it might not help, but I would still like to understand it a bit more.
Maybe you should get in touch with support and check what their opinion is about that.

[zzmike76]

@freeheeler sure, am attaching the 2 tours.

PS: the watch already did a trip to Finland and returned back, Suunto said there was no issue

Starting point was in both tours at 2694 meters

@zzmike76
do you have a link, too?
is the descent at the beginning correct?
strange that the watch obviously does not have an issue in the laboratory but in reality…

[zzmike76]

@freeheeler yes initial descent are correct, but altitude is wrong

here the links

thanks!

If the absolute altitude is correct (determined by satellite), but the altitude sum and the temperature are incorrect, the pressure sensor is defective.

[freeheeler]

@zzmike76
the peak alti is correct, the end alti is correct but the start alti is wrong, also the graph is wrong and the summary is wrong, too…
have you been charged for the watches trip to Vantaa?
Or is it still under warranty?
a few meters off is within tolerance in my opinion (start, absolute and total…). But what you present here is not acceptable and I would have my watch checked again from the customer service. Try to attach this information and describe your observation.

PLUS, halfway between Cabane Bertol and the Glacier next to Arolla there’s an unrealistic track with 2 straight lines…
By the way: great tour. I was at the Cabane Bertol in summer… many summers ago

[zzmike76]

@freeheeler thanks ! indeed it was a great tour

yes am still under warranty, I will try to send it again

[zzmike76]

@zzmike76 small update: sent the watch back home to Vantaa , this time they replaced the pressure sensor! I did not test it yet, but have a skitouring week ahead

@zzmike76

conditions are great at the moment! enjoy it!
