Continued Incorrect Ascent Readings

Nick Vlahandreas

Thanks for looking at it so quickly.

To answer your questions:

On my left wrist.
Beauttiful sunny stable day.
Always happens. Has been happening since Nov 19, otherwise the watch worked perfectly.

Dimitrios Kanellopoulos

@Nick-Vlahandreas we didn’t push anything that affects the altitude. Typically people here complain for undercounting ascent.

I assume it’s the baro model correct?

Nick Vlahandreas

Yes, its the baro model and its brand new from warranty.

Dimitrios Kanellopoulos

@Nick-Vlahandreas Roger that.

3 solutions.

One is my suspicion : Dirty / blocked sensor
Two is the way you wear the watch, with biking eg when you stand, the sensor holes get blocked and pressure increases , thus those dips happen.
Three ask for a replacement and I ll put a note to replace the unit

For 1.

Let the watch soak for 10minutes on lukewarm water. Take it out, and flush under the tap the pressure sensor holes. Make sure you see water coming in and out. Repeat this 3 times. Test afterwards. You can test this via a normal walking activity.

For 2

On your next bike ride:

USe a buff behind the watch (where the pressure holes are) so skin wont go there in case you push up on the bike. Or change position. You can mount it for example on the bike. A. quick mount can be done via the foam of the box (no need to buy) like the screenshot I ll attach on the end of this comment.

For 3

If all the above fail , I can help asking for a replacement for you.

TIPS how to create a 0 cost mount from the Suunto box:

Cut this hole on the foam part of the box

Nick Vlahandreas

Thanks Dimitrios.

I can rule out 1 and 2 as I’ve alwways worn my watch on this hand and had no issues for a year. Secondly, the watch is brand new and the sensors are no dirty.

So, I’d be more than grateful if you can help me out with another new unit.

Regards,

Nick

@Nick-Vlahandreas I do see those dips there so please first give a chance to rule those out please. Even if the watch is new , this can happen typically when eg shower foam / soap condenses.

That said, if you insist, open a case normally though support (support@suunto.com) and pm me the case number.

This is not normal. And your second watch!!?? It is got to be something with your setting. Do you use altimeter, barometer or automatic mode for altitude?

Dimitrios Kanellopoulos

@zvonejan those are not used anymore

nseslija

@Dimitrios-Kanellopoulos enlighten me about this please, even if a MC is used?

ups :). yes only in movescount and ambit 3. sorry

Dimitrios Kanellopoulos

@nseslija he uses Suunto app

Dimitrios Kanellopoulos

@zvonejan also S+Spartans but it’s no longer needed. (Altitude is the best option atm)

nseslija

@Dimitrios-Kanellopoulos ok, thanks, I was wondering if this is still around for SA use only…

Watch measure air presure and shows that like altitude. We all know that air preasure changes can came from 2 sides ( altitude, barometric changes). So if you run around stadium, suunto 9 can show you altitude changes, which is ridiculous. On ambit you just set to barometer and all changes are consider as weather changes and that is 100% correct. Am I wrong, Dimitri?

sartoric

@zvonejan said in Continued Incorrect Ascent Readings:

2 sides ( altitude, barometric changes)

actually, barometric changes (the sensor is a barometer) will be interpreted as altitude or weather changes.

For Ambit (and in the past for Spartans+S in MC) you can set in which way sensor data must be used.
Readings are 100% correct if you set this option correctly
Now on Spartans+S this option is “always” set to automatic and switches based on the other data

Only on stadium with barometer mode. If you set watch to altitude or automatic mode and run trail running, there is no guarantee, that all ascent difference is from altitude (some percentage is definitelly from weather changes). Only for old suunto watches of course

sartoric

@zvonejan
Well, yes, if you do trail running in “alti” mode and the weather is rapidly changing too the result could be distorted

freeheeler

@Nick-Vlahandreas
try Dimitrios’ suggestion with the buff…
I can write books about wrong readings when the strap is too tight or when the wrist position pushes the watch against the arm e.g. during gym workouts etc

Dimitrios Kanellopoulos

@zvonejan no you are absolutely right. Not only for that sport of course. If I recall correct (will check that for you) the track and field mode has that set for you. Of course to have some customization (ability to select) is welcome. I wont argue.

That said, have you used the track and field mode and got asc/desc values ?

mario_b

@Nick-Vlahandreas what does the ascent/descent values look like in the watch? when you review the activity? do you see the same?
