Figure 2: Step-by-step guide on how to use the COOSPO H9Z heart rate monitor.
- Attach the Sensor: Take the H9Z sensor and firmly snap it onto the two studs on the elastic chest strap.
- Moisten Electrodes: Fully wet both sides of the electrode area on the back of the chest strap with water or electrode gel. This improves conductivity and ensures accurate readings.
- Position the Strap: Place the chest strap directly against your skin, just below your pectoral muscles. The sensor should be centered on your chest.
- Adjust for Comfort: Adjust the length of the strap to ensure a snug yet comfortable fit. It should be tight enough not to slip during activity but not so tight as to restrict breathing.
