The primary reasons for receiving a 'Insufficient signal quality' result usually involve the camera not receiving a proper signal from your fingertip or movement during the measurement. To address this, try the following steps: - Remove your smartphone's protective cover to ensure better contact between your finger and the camera lens. - Apply gentle pressure on the camera with your finger. Too much force can distort the signal. - If one finger doesn't work well, switch to another or adjust its position slightly on the camera lens. - Ensure you are seated and relaxed during the measurement, avoiding any movement or talking, to minimize signal interference. If these adjustments don't help, consider whether: - Calluses or physical conditions of your fingers might be affecting the measurement. Try using a different finger or the base of your thumb, which might provide a clearer signal. - Cold hands could be reducing blood circulation to your fingertips, making it harder for the app to detect the necessary volume changes in your finger tips. Warm up your hands before taking another measurement. - Hand tremors are present; stabilizing your hands on a table or placing the smartphone on your finger instead of pressing your finger onto the camera might help. If you continue to experience issues despite these troubleshooting steps, restart the Frontier Pulse app and attempt a new measurement, ensuring your finger is correctly positioned and you remain as still as possible.
