Blood oxygen

If Suunto dive computers are as accurate as the Race 2, then good night.

@Tomas5 Hey, I’m going to try to describe how the oxygen measurement (which works very reliably on all Suunto watches, by the way) works. The most important thing to note is that any light shining on the sensor negatively affects the measurement. To ensure reliable readings during the day, I take the watch off and hold it on my wrist where it usually sits. I don’t fasten the strap, though. I hold the watch between two fingers, then gently press it against my skin and start the measurement without moving my hands. This gives you perfect control and shows you that no light is reaching the sensor. Just try it out. The important thing is not to press the watch down hard, just gently.

@GiPFELKiND Also ich trage meine ganz normal wie eine Uhr. Und sollte ich mal messen dann funktioniert es perfekt. Aber in Wirklichkeit ist es halt eine schöne Funktion die kein Mensch braucht. Aber schön wenn man sie hat.

@GiPFELKiND Ich meine nur dass die Messung auch beim normalen Tragen supi funktioniert.

@Cyclepunk good night to you too…

@GiPFELKiND short answer: sounds good, doesn’t work
long answer: i already tried multiple ways including what you describe, i tried measuring during evening when it was already dark outside and no light at room. It doesn’t work at all. Until recent few days. It worked just normal 99% time and manual measurements was successfull and night measurement measured around 96-98% every night, no problem at all. Only just few nights ago it started to measure values below 90% at night and manual measurements doesn’t work 100% of times. I really don’t believe that sudenly from day to day i somehow lost ability to do manual measurement from 99% successful to 100% unsuccessful. Now it behaves exactly like with earlier version of firmware where i had this anoying bug.

@GiPFELKiND not sure who or why give you dislike, but maybe people with this bug are just anoyed when someone blames it to be user error. When this is obviouse bug/issue in firmware or hardware.

And since this issue occured (around last 5 days) battery consumption went up too. From 5-6% a day to 8-9% a day.

@GiPFELKiND So since soft reset did nothing. I tried hard reset, manual blood oxygen works since than 100% of times i tried. Even during daylight, only requirement is to stay still and don’t move even with fingers. That means it is definetly not problem with how i do measurements usually since before hard reset 100% of time it failed, after hard reset 100% time success even when i am at daylight and don’t cover watch.

Only downside is to need to customize sports modes again.
@Dimitrios-Kanellopoulos does suunto acknowledge there is still bug in night bloodoxygen and manual bloodoxygen measurements even in latest firmware 2.48.16 ? It worked for around 2-3 weeks after update than suddenly stopped. I will se how long it will work after this hardreset.

@GiPFELKiND
I dared to say thank you recently and got dislikes. User base changed over the last years…

Sometimes it’s a problem when scrolling on mobile.
you can press the like/dislike button and you don’t even notice it

@ChrisA i think suunto forum people are one of the niciest comunity i ever saw. Compared to forums of different brands/products. But everybody sometimes have harder day and can be more sensitive to something. Sometimes maybe language barier when somebody means some as joke or sarcasm, but it is taken literaly etc.

I agree too that sometimes on phone i give like/dislike just by accident by scrolling, if i notice i undo it right away. But overal when somebody dislike some “help” response, it may just mean it didn’t work for him or as feedback that it didn’t helped. I think is not needed to take it personally or feel bad about it.
