I've been observing some weird behaviour when running on a threadmill. It goes like this:
- Day 1: correct pace
- Day 2: pace too low - I did Calibrate & Save
- Day 3: pace too high...
What is more, on Day 2 I noticed the pace changing when I raised my arm, to me it seems that the pace was being taken from the watch. On Day 3 raising my arm did not change the pace, like the pace was being taken from HRM 600.
How do I tell the source of pace during an activity?
And wondering if the issue affects heart rate data too...
When I go to the sensor settings while HRM 600 is disconnected, I cannot see "HRM Pace & Distance" at all, no way to select between automatic and manual calibration. When HRM 600 is connected, I can see that menu but it is greyed out and a subtitle says "Only ANT+". But the user manual states in one place: "You can view your running pace and distance on your compatible fēnix watch when connected using ANT+ technology or secure Bluetooth technology.", and a little later: "If you are using an HRM-Fit or HRM-Pro series accessory, pair it with your watch using ANT+ technology, rather than Bluetooth technology."
So does HRM 600 also require ANT+? And if I switch to ANT+, will I loose some statistics?
Any help greatly appreciated.
