1. Incorrect wearing position: heart rate monitoring usually requires the watch to be close to the skin for accurate measurement. If you don't wear it in the right position, such as wearing it too loosely or too tightly, or there are obstacles (such as clothes) between you and your skin, the green light may not light up normally, resulting in the failure of heart rate monitoring. It is recommended to readjust the wearing position to ensure that the watch is in close contact with the skin.
2. Ambient light interference: oppowatchse uses a green light source to measure the heart rate. If the ambient light is too strong or too weak, it may affect the brightness and stability of the green light, resulting in the failure of heart rate monitoring. It is suggested to measure the heart rate in a more suitable light environment to avoid too strong or too weak light interference.
3. Insufficient battery power: If the battery power of oppowatchse is too low, it may cause the green light to go out or the brightness to weaken, which will affect the accuracy of heart rate monitoring. It is recommended to charge in time to ensure that the watch is fully charged.
In addition, it should be noted that although the heart rate monitoring technology is quite mature, there may still be errors in some special cases, such as faster or slower heart rate and weak heart rate signal. Therefore, for users with special circumstances or high requirements for the accuracy of heart rate data, it is suggested that more accurate heart rate monitoring should be carried out under the guidance of medical professionals.
In addition, oppowatchse also has other functions, such as exercise monitoring and sleep monitoring, which can help users fully understand their health status. Therefore, even though there may be some limitations in heart rate monitoring, more health information can still be obtained through other functions.
