When I use the Exercise mate function with HRM, the value of HRM displayed on S Health app is not exact. What is the problem?
First of all, check to wet both electrodes on the back of the heart rate monitor strap to create a strong connection between your chest and the Transmitter.
Thus confirm that you paint the water or ECG gel on Transmitter, besides check that wrap rightly and tightly the strap around your chest.
