Wearing the Polar H1 and H7 Heart Rate Sensors
The electrode areas on the reverse side of the strap detect heart rate. The connector sends the heart rate signal to the Performance Monitor.
Note: The Polar H1 Heart Rate Sensor was previously called the Polar Wearlink chest belt.
To wear the chest belt:
- Wet the electrode areas of the strap under running water and make sure that they are well moistened.
- Attach the connector to the strap. Adjust the strap length to fit snugly and comfortably.
- Tie the strap around your chest, just below the chest muscles, and attach the hook to the other end of the strap.
- Check that the wet electrode areas are firmly against your skin and that the Polar logo of the connector is in a central, upright position.
Additional Tips
Review the following tips to ensure successful heart rate transmission.
- If the chest belt is having trouble picking up your heart rate, try rotating the chest belt to the left side of your torso (closer to the heart). You can also try moving the chest belt higher or lower on your torso.
- Warm up, so that you are sweating a bit, before putting the chest belt on; this can help establish a connection between the skin and the contacts.
- Try using electrode gel on the contacts.
- Excessive body hair can degrade performance; shaving or moving the transmitter to a smoother area can help.
- Excessive body fat can block the signal from the chest belt. Position the transmitter in the leanest area possible, and avoid body parts, like the breasts, that are composed primarily of fatty tissue.
