A. Do not swim with smart bracelet. We also don’t recommend showing with it , though the water won’t hurt the device ,wearing it 24/7 does nog give your skin a chance to breathe.Whenever you get your bracelet wet , dry it thoroughly before puting it back on
B. When test the heart rate monitor, let hands keep the ground parallel,and to prevent light leakage too
C.If you charge the bracelet for the first time, if there is no response after more than half an hour after charging, you’d better charge it for more than 4 hours to try.
D. blood pressure and heart rate working principle:
The principle is the photoelectric transmission measurement method. In principle, the sensor that the wristband contacts the skin emits a beam of light on the skin and measures the reflected/transmitted light. Because the blood absorbs light at a specific wavelength, each time the heart pumps blood, the wavelength is absorbed in large amounts, the blood is red, the red light is reflected, and the green light is absorbed, so that the heartbeat can be determined. . Our wristband combines green LED light with a photosensitive photodiode to measure the amount of blood circulating at the wrist at a specific time to obtain heart rate information.
so in this case , maybe even you test on some materail that can can reflective the light , maybe you also can read the data of blood pressure and heart rate.
If you want to test more accurately, you’d better test it several times and then average it.
This is not a medical device. The test data is not necessarily 100% accurate. if buyer care about it ,please don’t buy it
charging port:charing clip
