How to Put on the Chest Strap

Before putting on the chest strap, moisten the electrodes (the rubberized part) with water or ECG gel.

1. Prepare the chest strap and snap on the sensor Check that the chest strap is in good condition and that there is no visible damage. Carefully snap the sensor onto the chest strap.

2. Moisten the electrodes Before putting on the chest strap, moisten the electrodes on the back of the strap with a small amount of water or ECG gel.

3. Fasten the chest strap Fasten the chest strap just below your chest (around the level of the lower ribs). The strap should be tight enough to stay in place but not uncomfortable. Make sure that the electrodes are placed directly on your skin and are not covered by clothing.

4. Check the connection and sensor orientation Ensure that the sensor and chest strap are not reversed. The sensor’s numbering should face upwards, and the sensor’s logo should not be upside down. Also, in the Kardi Ai app , make sure that the chest strap is correctly connected to your phone via Bluetooth - when properly connected, the text Ready for recording will appear in the app.

5. Start measuring Once the strap is properly fastened and connected, you can start measuring in the Kardi Ai app .

6. Monitor strap fastening Regularly check during use to ensure the strap fits comfortably and does not become loose.

After correctly fastening the chest strap, ensure that the measurement data is displayed in the Kardi Ai app and keep your phone close to the chest strap.
