Suunto 9 Baro - Elevation profile issue

[Cédric Dodrimont]

Hi All,

Since a couple of weeks, the elevation profile is totally wrong with on my suunto 9.
Each time I start an activity, it starts with a big elevation.
I run with a friend who have also a S9B, and the altitude profile is totally different.

Example:
My elevation profile:

Same activity on S9Bof my friend:

Other example:
My S9B:

My Friend:

I have a lot of other examples.

I’ve tried to reset the watch, nothing changed.
I’ve tried soaking in hot water… same results.

Do you have other ideas?

Many thanks!

Cédric

Many thanks!

Your elevation profiles have rather small elevation changes.
First guess: Temparature has an influence on this - are you and your friend wearing your watches in the same way? Like under or on top of clothes etc?

[Cédric Dodrimont]

@egika Thanks for your reply. We are wearing the watch in the same way, in top of clothes.

My last run this morning: I run 7km on a road then return by the same road.

My watch:

Friend’s watch:

Maybe the barometer is broken

@cédric-dodrimont if the watch is still under warranty, contact support, they can take your watch and check.

Also, search the forum for the “fridge test”.

@cédric-dodrimont I’d say the problem with the barometer is more likely your friend.

[Cédric Dodrimont]

@isazi Thanks, unfortunately the watch is no longer under warranty.

I’ve done a fridge test, but I don’t know what to conclude (The fridge has been opened after 3 hours):

@cédric-dodrimont
just to be sure: did you manually adjust altitude before your activity?

[Brad_Olwin]

@cédric-dodrimont yours is a Suunto9 non-baro model? The altitude will depend on GPS so try the best satellite system. However, you will not get the accuracy of a model with a barometer.

@brad_olwin He’s got an S9 Baro. According to the temperature graph

Afair the temp sensor is not the barometer.

[Pavlas]

@sartoric Does the S9 non-baro has a temperature sensor?

[sartoric]

@pavlas
Well, that’s a good question

So now I’m am at as much a loss as all of you.

OP says 9 Baro in the title

Hidden in plain sight

So the 9 has no temp sensor ? I didn’t expect it

[Egika]

@sartoric yeah, temp sensor is technically needed to compensate temperature drift of the baro sensor. So it is kind of integrated into the baro sensor.

[Cédric Dodrimont]

@freeheeler For this one maybe I adjusted the altitude manually. I will try to do a new activity end of the day without adjusting it.

It’s a baro watch, when I look at my activities, it seems issues started the 4th of January. Before this date everything was fine.

[DMytro]

@sartoric it’s proximity to the skin makes sensor useless for any other purpose.

@dmytro Except when swimming
