S9B Strange HR and HR-Zones behavior

Thanks for the suggestions. I made some new observations.

@freeheeler The battery is not old, I’ve changed it recently. But I’ll swap it again (just need to get one) to rule that out. Problem #2 seem not be related to the strap. I’ve started a workout WITHOUT the strap today and the HR was immediately “locked” into Zone 4 and even though I was standing and doing nothing, the HR was quite high (above 100 - but definitely NOT in Z4). It slowly decreased to 60. Strange behavior.

@Brad_Olwin Yes yes, I soak it under running water, or when I’m moving to a location with a car, I even have a bottle with water for this purpose

@Egika Indeed, it doesn’t mach anything it just “locks” into that specific zone on the watch and that’s it. As described above, it doesn’t seem to be related to the HR strap, because I’ve started a weight training today without the strap and it immediately locked into the Z4 (orange horizontal line) on the watch itself.

@Dimitrios-Kanellopoulos iOS 15.5, but it’s happening on the watch itself. I assume it’s not related to the OS. The watch has the latest available update. Maybe a soft reset?

EDIT: Happened just 2 minutes ago. Locked in Z4, no HR strap.

@tomasbartko for the picture I see with the lock, is it belt or ohr. It won’t move if it doesn’t have HR data

@Dimitrios-Kanellopoulos Nope, no HR belt, just OHR.

But I went for a run just now - with the HR belt:

Also the GPS was a bit weird today, because I’ve definitely started where I ended. Not as shown in the picture.

And one more:

@tomasbartko So, have you tried the soft reset already?

@tomasbartko
I’ve only had an incomplete track once. I’ve started running with an almost empty battery.
let’s collect more info. I don’t think your watch is broken. A soft reset would be the first thing to try. If this doesn’t help, maybe installing the latest firmware again could be a solution?

@inkognito Yes sir, did that before I went out and, as you can see, it didn’t help. I’ll try a hard reset.

@freeheeler Very interesting. I have 65% of battery left now, so that might not be the issue, I hope. I think the latest firmware “broke” the software on the watch in the first place. I’ll try a hard reset, reinstall the firmware and report back.

Less than 15 minutes before starting the activity? Then you started without AGPS, may explain the missing part, there was no GPS lock.

Well, if this affects only you it’s more probably a watch issue, and not a software one, as there’s thousands of people with this version.

sorry… I missed recognizing that the start was missing, not the end.

@tomasbartko
you might want to do some tests with watch integrated OHR and even a HR strap from a friend, before you do a hard reset and investigate further

I forgot to mention that I have used a custom Trail running sports mode. Tried also the default ones and a different HR strap, tried OHR. This is from this morning, for example:

I think it’s pointless. I’m going to try factory reset now, although I have mixed feelings about that.

@tomasbartko
I have in memory that it takes some time before the zones are adjusted correctly. what do you see when you look into your older activities that were faulty back then? do they still look the same?

@freeheeler Yes, unfortunately they all look the same. No change at all.

Brad_Olwin

@tomasbartko Before you do the reset, do you have both default zones and sport-specific zones set up in the watch? And, are they different?

@brad_olwin Well, I did the reset and have good news - the problem with the stuck zone is gone. Did a few tests and it behaves normally now

Hello everyone. I have the same problems when I train with the chest HRM. The firmware is up to date, the heart rate monitor battery is new, I wet the HR belt several times during training, but the heart rate was inadequate. I had set up HRZ4, I had turned on training peaks - cycling power, which all the time showed rtss 0.00, NP 0 (That I also don’t know why, but I understand it’s another topic). The next workout I will try at the same settings, but with OpticHRS. I haven’t reset the watch yet. It would be grateful if anyone would comment on these issues. I wish everyone health!

@ingiliz as you see the problem that @tomasbartko had was that HR was stuck in Z4 on the watch, even without HR being measured. So you need to test with OHR and with no HR at all before we can say if it’s the same issue, or just a broken HR strap.

@isazi Thank you for the rapid response. Until ten days ago I used the same chest belt with traverse alpha and I believe it. Today I just checked the battery.

@ingiliz as @isazi mentioned, try the same activity without the HR chest strap, just OHR on your wrist. But overall it seems to be a bit different issue than I’ve had. If it works with OHR, then most probably you just need a new strap and don’t have to reset the watch. Just my two cents.
