How to wear a heart rate sensor with fabric strap?
Polar heart rate sensor measures the ECG signal from the chest. This is where the signal is the strongest. The type of the ECG signal slightly varies from person to person. The ECG signal strength can depend on chest form, the anatomical location and position of the heart, position of the electrodes, and the amount of body fat. If the ECG signal is weak, the signal can get disturbed more easily. To ensure accurate detection (needed before measuring is possible) the contact between skin and electrodes needs to be constant. To ensure good contact:

  • Moisten the electrode areas of the heart rate sensor. At the beginning of the exercise session your skin may be dry and the moisture will help ensure better contact. When you start to sweat the contact will improve because the salt in sweat conducts electrical signals very well. If your elastic strap has plastic electrodes, saliva is a good conductor as well. If the strap has fabric electrodes, it is essential that you moisten them thoroughly with water before exercise.
  • Tighten the elastic strap. If the strap is loose, the movement of the electrodes will disturb ECG signal detection. If the standard-size strap does not fit comfortably, larger and smaller straps are available as accessories.
  • Try different sensor positions to find the best for you. If the signal is weak when the sensor is placed right under pectorals (recommended position), move the sensor left or right, lower or higher to find the best signal. There are known cases where heart rate is detected better when the sensor is turned with the Polar logo upside down and facing out, or even when attached on the back.
  • Try shaving a small area on your chest. Chest hair may weaken contact. If you cannot find your heart rate signal by positioning the sensor differently or using conductive gel (only for plastic electrodes), shaving a small area for better conductivity may help.
