Two Questions about HR Strap

[Sergei Ladeishchikov]

theoretically yes, but the discharge was present for several days in my previous H10, I had to attach and detach the sensor to the belt every training. I checked the detection of the Suunto belt when not in use, through the watch and SA, the belt was not found))

it is only detected when the skin closes the electrical circuit

[Tami999]

So far Iam happy. HR seems very stable now, without huge drops. With same activity I had 140-150. Before 130-150 with drops to 60 or 40. I thought Iam dying
. Does anyone know if its good to use CR2032 battery instead of 2050? I got a few brand new.

[Brad_Olwin]

@Sergei-Ladeishchikov You do not need to disconnect the sensor. I never do.

[Sergei Ladeishchikov]

@Brad_Olwin I thought so) but I have problems with the heart rate, sometimes there is no data from the belt for 20 seconds or 1 minute. My belt is new, about 1 or 2 weeks. Almost every long workout I notice the lack of data, usually I am already warmed up enough and the belt is wet. SA showed the pulse at this moment as a straight line, but in Humango and Intervals zero readings are visible. Before the Suunto belt I used Polar H10, I had this problem with it, but the belt was quite old and the pulse sometimes just hung, but did not disappear. Does anyone have such behavior of the belt or is my belt or sensor faulty?
I use SV.

[Brad_Olwin]

@Sergei-Ladeishchikov Maybe the battery is old, the belt should show HR immediately if wet. Mine does. I assume you have replaced the battery. What color is the material between the contacts on the belt, it should be grey not black. This is on the front side between the contacts that the sensor attaches to.

[Sergei Ladeishchikov]

@Brad_Olwin The battery is new, shows 100%. The contact pad is gray. The data is interrupted not at the beginning, but during the activity. Since this happened with the old H10, and now with the new Suunto, could the problem be in something else? For example, in the connection between the sensor and the watch?
A recent example is below, 45-46 minutes.


Today’s activity also had a couple of gaps 2 hours after the start of the activity.

This could be due to the strap getting dry and/or a tech shirt that may cause static. The first graph is HR, correct? I see where data are missing. I have had the same occur to me when on a SkiMo outing caused by either the belt not completely contacting the skin and dry, cold weather where the belt is not wet and I am not sweating enough. You might try a gel on the belt, it looks to me like the connection between you and the belt is an issue.

[Sergei Ladeishchikov]

@Brad_Olwin Yes, the first heart rate graph. Yes, I will try using the gel. Thank you!

@Tami999 I’ve used CR2032 batteries in my Suunto HR belt for years without any problems

[VoiGAS]

@Mattg576 Nice Hack! So the battery should have more capacity? Less effort to change and less trash

And still waterproof? 2032 are little thicker no?

[Mattg576]

@Mff73 I haven’t swam in the belt but have been wearing it in some torrid weather & I sweat quite heavily so it’s had many total soakings with no issues at all

[Ecki D.]

Sorry for re-using this thread, but maybe someone knows if it makes sense to turn off the wrist HR sensor when the HR belt is connected?
I did this on my last runs to maybe save battery life.
I once did a bike ride where the HR belt stopped recording, but the wrist sensor didn’t take over, so I think it’s not used anyway.
I haven’t been able to test it yet, so I thought maybe someone here knows.

[Mff73]

@Ecki-D.
Once a’ activity is started with one HR source, it doesn’t change.
I personnaly deactivated wrist HR for my running sportsmodes, to avoid having to check if the belt is well connected and activated and let the watch not show any HR at pre-start screen if my belt is “faulty”. Apart from this, if a belt is connected, it should use it by default over the OHR

[Ars Vitae]

@Ecki-D. To complement, maybe that would help too. When you use the activity you don’t need to have HR wist additionally turned on, OHR starts automatically. The rest was perfectly explained by @Mff73 .
