Heart rate is wrong in 2km first!
-
@hieus try staying on the ‘start’ screen (when you get the gps and heart locks) for a couple of minutes, i.e. from when you put your shoes on instead of when you’re out. I had the same issue than you (with a S9 though), and that solved it
-
I had the exact same behaviour with an Ambit3 and HR strap, I presumed that the strap is starting to fail, but this is interesting if you get the same with optical sensor too. Now I’m confused: maybe my strap isn’t failing (I need to measure the resistance then) and something strange is happening when data is interpreted by SA?!
-
If you don’t see something like this after you take your watch off, it’s too loose.
Also, as others mentioned, have ohr on (workout start screen) during your preparation, warmup, etc. 5 minutes before hitting “start” should be enough.
Shaving wrist also helps but for some people it’s too hardcore
-
@Łukasz-Szmigiel I guess then I need to shave my chest
-
@andrasveres yeah I’ve heard about some furry runners that have problems with chest straps but I was referring to the original poster
As with hr strap - I’d check the battery first or maybe the belt is worn out.
-
@Łukasz-Szmigiel Just kidding.
Regarding the strap: battery change was the first thing done, with no result. Planning to buy a Polar H10 as Suunto straps tend to start fail in no time.
Sorry for the off topic. -
@Egika said in Heart rate is wrong in 2km first!:
Where on the arm
I wear it on my left wrist and tight, the weather is so hot (Hanoi, Vietnam weather)
-
@jw-cou yep, i will try with your tip.
-
Had the same experience too. Have a Ssu and have to use hr belt. If you want a precise measurement use a hr belt. I had 2 suunto hr belts and - excuse me - they are rubbish. Suunto can’t that. So I bought a H10 and I’m pretty satisfied. No problems at all. It’s worth the money if you want reliable hr data
-
@Stefan-Kersting there are new belts and improved ones though. If you still have a warranty ask for a replacement. They are white on the sensor buckle.
-
@Dimitrios-Kanellopoulos ok then my comment applies just the older ones. Don’t have experience with the new ones. I don’t have warranty any more but happy with the polar
-
@Stefan-Kersting I know pal, just saying
-
New belts have a different problem, they evaporate quickly from suunto store.
-
@lexterm77 yes and manufacturing is slow due to Corona. Difficult times for EU factories etc
-
I bought two just in case this coronaverse shit hits the fan.
-
-
@jw-cou I tried as your idea but the first 2km heart rate was still wrong
-
@hieus I’ve no other option to suggest, sorry
-
@hieus
I have not read all advices you got, but eventually try to wear your watch on the other wrist. Maybe blood flows are better. -
@Mff73 This afternoon, I wore a watch on my right wrist and the problem was solved.
Thank you all!
