The correct way to wear the arm strap
Remember not to wear on the wrist, it is arm band, should be worn in less fat, more muscle parts (rich capillaries)
It should be tight, not loose, not feel swollen
If too loose, photoelectric head can not adhere to the skin, the data is not accurate.
If too tight, can interfere with blood flow, leading to inaccurate data
