Normal walking can be recorded.) For the accuracy of the estimated data, you can set the correct athlete information on the profile page first. Estimated Distance Turn on the 'Steps' switch on the X2 PRO connection details page and record your workout directly with the X2 PRO.

BBP Blood Oxygen Measurement

How To Measure Blood Oxygen？ 1. ​Make sure your BBP fits snugly and comfortably on your upper arm. 2. Open the XOSS App and connect to BBP, enter the connection details page > measure blood oxygen. 3. Stay still. 4. Wait a moment. The measurement takes 15 seconds. How To Get Accurate Results? 1. During the measurement, relax your arms and place them flat on your lap or on a table, and try to stay as still as possible. 2. Make sure the armband heart rate monitor is not worn too loosely. Other Factors Even under ideal circumstances, the armband heart rate monitor may not get reliable blood oxygen measurements every time. A small percentage of users may be unable to obtain any oxygen measurements due to various factors. - Cutaneous blood flow (the amount of blood flowing through the skin) may affect the measurement results. Skin blood flow varies from person to person and can also be affected by the environment. For example, if you are outdoors in the cold, the blood flow to the skin at the wrist may be too low for the sensor to obtain a measurement. - Permanent or temporary skin changes (such as some tattoos) may also affect measurements. Some tattoos' ink, pattern, and saturation can block light from the sensor, making it difficult to obtain measurements. - Various activities you perform may also prevent measurements from being completed successfully in the background or when needed. Certain postures can also cause measurement failure, such as arms hanging by the side or hands clenched into fists. - If your resting heart rate is too high (more than 150 beats/minute), you will not be able to measure blood oxygen successfully. Unstable Blood Oxygen Saturation If the blood oxygen saturation data is unstable or does not appear, you can try: - Stay still while the device reads your blood oxygen saturation. - Wear the heart rate armband tightly on your forearm or upper arm. - Keep your arm at heart level while the device reads your oxygen saturation. - Avoid applying sunscreen oil, lotion, or mosquito repellent where you wear the device. - Please avoid scratching the optical heart rate monitor on the back of the device.
