I have my second hrm run red version now. I bought it 2 months ago because my first reported way too high heartrate while running. Usually my heartrate at an easy run is about 110-120 bpm. The last few runs i get a heart 150 plus. Sometimes 170. My labtest max is 152. So clearly it is way off. I rinse it off every time after use and wash it after a few use. I wet it intensive bedore use. I disabled ohr on my forerunner 945 so signal is coming from the belt. Fw is the latest on watch eand hrm. It worked fine in the beginning but after a few months it has the same false readings in my perspective. Any thoughts what to do, besides returning the belt?
