HR sensor on watch and external at the same time
I have an external HR sensor and everything is ok, gives measurements etc.
In the watch itself, in the options for a particular exercise I have an option such as disable HR monitoring from the watch.
What is the relationship during exercise - measurement from the external sensor and leaving this option enabled in the watch?
HR is measured from both sensors?
@matt-r nope, if the watch connects to the sensor, it uses just that automatically. No need to toggle watch HR off every time.
@DMytro Ok, that’s generally what I thought
By the way - is the possible lack of VO2max measurement affected by turning off the heart rate on the watch?
I bet not, but… After disabling this option - with today’s 8km run, 45 min normal pace. I got no such measurement - hence my interest in this duplicate option.
@matt-r if HR was measured my HR strap, VO2Max shouldn’t disappear.
@DMytro Ok - another thing I reasonably expected
Then I am now curious why there was no measurement of VO2max
@matt-r did you have vO2 before? Or did you reset your watch recently?
@DMytro Yes, I was doing a hard reset - I had a problem with the update.
However, I thought that the VO2max measurement should be read - as it is written in the instructions - even after the first exercise, but lasting a minimum of 15 min
@matt-r sometimes 1 exercises is not enough. Do a couple more and everything will be ok
@DMytro Sure, that’s probably how it will be.
But strange, because I remember exactly that after an identical first run I immediately got a VO2max sample and now I don’t
@matt-r the firstbeat vo2max algo has some filtering process, which throws away portions of data if it thinks they are faulty/not accurate enough. Since it’s colder now, maybe it impacted the quality of the data and algorithm decided the data wasn’t enough to give you a reliable value.
@DMytro oooo! that’s an interesting observation, I hadn’t thought of that
Cool tip - such for general understanding of Suunto ecosystem
