incorrect heart rate measurement
I have the following problem with my Tomtom Runner3. For example, while cycling my heart rate is continuously between 150 and 160. But suddenly it shows 87. Then the watch jumps back to that 150. I almost never have a cycling session where the heart rate measurement never gives those crazy low values. So my average is never correct! What could be the cause of this? How to solve?
