Question about heart rate monitor

isazi

@Miroslava ZS not measuring anything suggests a very unstable R-R stream. If you see a wide cloud of points for the R-R data (I use runalyze to check that) you can try to clean your strap. If it is an old strap, maybe it reached its end of file.

Sales in Suunto Smart HR in SP…

@suzzlo thank you, I saw that there are promotions, but in the future, if Polar is not repaired, I am considering buying a Coros HRM for my wrist, also for comfort

Miroslava

@isazi thanks for the observation but the polar h9 is new both the sensor and the belt, so that’s why I don’t understand it, but I gave it to a friend to take a look at because it’s very strange behavior. that’s why I wrote here that where could be the problem. so far my old h10 has worked beautifully for me and so has zonesense. I also want to ask does zonesense still only work with a chest belt? I read somewhere that it should also work with optical sensors

@Miroslava just keep in mind that Zonesense doesn’t work with Coros HRM.

Miroslava

@timecode Well, I just wanted to know if zonesense only works with a heart rate monitor, because I read somewhere that zonesense already works with optical measurement.

@Miroslava As far as I know, ZoneSense does not work with optical heart rate sensors.

@Miroslava you need an ECG basted HRM for ZoneSense to work. Optical won’t do it…

Miroslava

@2b2bff @maszop thank you guys, never mind i will see for me i am woman is better monitor on my biceps as chest strap.

I have noticed that using a chest strap, the average heart rate per lap is always lower than the real average that is displayed on Strava. This doesn’t happen using the watch’s optical heart rate sensor.
ZoneSense works fine for these activities…

I believe that this is a bug that has been present for several years. I reported it many months ago through Suunto App and am disappointed that it still has not been fixed.

Another member once mentioned that maybe the cause is that the lowest heart rate per lap is logged as zero in Suunto App.
