4.2 Attach the Sensor to the Chest Belt (for ECG Recording)

If you plan to record ECG data, a chest belt (e.g., from Polar or similar) is required.

  1. Moisten the chest belt (on the side that touches the skin) slightly with water. This improves conductivity and reduces noise.
    āš ļø Do not moisten the BI-Vital sensor itself. It is not waterproof.
  2. Attach the BI-Vital Sensor to the chest belt so that the printed text on the sensor is upright and readable.
  3. Ensure that the electrodes of the belt have good skin contact.

For a visual demonstration, you can watch this short video (showing the process with a Polar H10, same principle applies for BI-Vital):
