Hi,
my HRM Pro Plus seems to be acting weird. During activities, especially strength activities (push ups, ..), the heart rate plateaus for up 15 seconds sometimes. In another thread, I've read that if the hr can't be measured it keeps the previous value, but it's weird since isn't it supposed to measure every second? How is it for you? Is this normal? (Software 8.8, battery is fine and I'm wearing it tightly, paired with a FR955 Solar)
Zoom into the pictures to see it more clearly.
Thanks!
