What are the factors that affect the heart rate detection of Huawei WATCH FIT 3?

Heart rate detection is influenced by many factors such as environment and wearing. If you find that the heart rate measurement fails or the heart rate measurement data is inaccurate during use, please check as follows:

When you don't wear the watch or wear it loosely, the watch and wrist can't fit well and can't identify the pulse signal of the wrist. Please make sure to wear it correctly, and the watch fits comfortably with the wrist skin (wear it slightly tightly). Don't wear it on your wrist. It is recommended to wear it at one finger above the wrist.

If the watch slips during exercise, please pay attention to push it back and try to keep it stable.

Make sure that the back of the watch is clean, dry and free of foreign objects. Excessive sweating during exercise may cause the watch to slip and sweat to block, which may lead to inaccurate heart rate measurement. Please dry your sweat before putting it on.

Please ensure that the measured arm position is free of scars, tattoos and excessive hair coverage, which may lead to poor contact between the heart rate unit and the skin.

In cold weather, the blood flow of wrist capillaries changes, which leads to the failure of heart rate sensor to obtain relatively effective signals and affects the accuracy of heart rate measurement results. At low temperature, it is recommended that you wear gloves/long sleeves to keep warm and warm up before measuring your heart rate.

Exercise regularly (such as running, walking, cycling, etc.). ) It is easier to accurately measure heart rate, while irregular exercise (such as playing ball and free activities) may not be able to accurately measure heart rate, and wrist strength exercise (such as weightlifting) may not be able to accurately measure heart rate. Please turn on the corresponding movement type according to the movement menu of the watch.

During exercise, if the heart rate detection data of the watch is abnormal, please keep the watch face up and stand still 10- 15 seconds. If you can't detect the results for many times in a row, I suggest you restart your watch and try again.
