HRM Pro connected but not measuring hr from start

1471947

I think my HRM Pro is not measuring my hr from the start of my run, but kicks in after 10-15 minutes. I assume it's just because it doesn't have a good enough skin contact, but but it would be nice if my FR 955 would tell me that it isn't receiving a hr from thew belt...

    One way to see whether the watch gets HR and HRV from the HRM strap, is adding the Respiration Rate data field to one of the activity screens. During an activity, it only shows a value when HRM is connected and broadcasting HR & HRV.

    Please note: if you do not start the activity, just looking at the activity screen, the field may show a value even without the HRM strap, because the watch can measure HRV (and hence the respiration rate) with the wrist sensor when you stay still, and did not start any activity (except of breathwork, yoga, or meditation). In the moment you do start the activity, and have no HRM connected, the value disappears even if you stay perfectly still - only HRM is used to measure HRV / Respiration Rate during an activity.
