Howto reset watch and "keep" data ?

Hello,

I would like to "reset the OHR" sensor of my watch if that's possible.

How should one do it (without loosing all it's settings/music) ?

I ask this because in "Strenght" I displayed the heart rate and while doing a serie of 10 "strict" muscle-up my heart rate stayed at 55 which would be really nice if that's were true.

Thank you very much.

    You can only reset the whole watch, not single components.
    Your only problem is, that it is not meassuring right when you do muscle ups?

    OHR has its limitations because it needs to see blood flowing. Strength workouts are hard to measure because the tension in the muscles reduces visible blood flow (the location on the wrist is a bad one if you recall anatomy). The movement on a muscle up and the muscle groups used will not make it easier. I would also suspect that you wear the watch to loose to get it a little bit further away from your hands back? I have to do it when I do burpees, push ups or similar things because my hands back pushes the start button when it is not supposed to be pushed.

    The same measured with my Vivosmart 4 is about the same on the 945 with HRM-Tri.

    Single arm pull-up on same or other arms as the pull-up is also not of any use, even pistol squat are a non go in respect to OHR on my 945.
    When I do slow running I got about 130 rpm with HRM-Tri and 190 with OHR on the 945 (Vivosmart 4 is also fine).

    Unfortunately it's not only in muscle-up but for anything that OHR seems completely off.

    OK, then, how to do a "full" reset and restore all settings ?

    Thank you for your answer.

    Wrist Optical HR isn't accurate when weightlifting.

    • Certain Types of Activities Can Affect Heart Rate Performance

      Activities that cause flexing of the wrist (ex. rowing, weight lifting, or gripping a tennis racket) may create an effect similar to wearing the watch too tightly and restrict blood flow.  When this occurs the watch may have a difficult time detecting an accurate heart rate. 

    • Additionally, HR is calculated differently for each activity.  Use the activity app that matches the activity being done.  For example, using the Elliptical app while running outdoors could result in incorrect HR being recorded.

    You need a chest strap HRM - or at least an upper-arm optical sensor like the Polar OH-1 - for weightlifting.
