产品是不是正常是根据产品的spec定的。但是根据血氧的测量原理，血氧是可以独立测试。

As the smartwatch measures the blood oxygen level, red light reflected off the subcutaneous tissue or bone is projected onto the body surface. The light is reflected from the subcutaneous tissue or bone and presented to the smartwatch's sensor, which determines the difference between the reflected and emitted light

• 如果测出一个血氧20脉搏4我会觉得是误读，这个以假乱真。。。遥遥领先啊 -cowpi- ♂ (0 bytes) () 09/12/2023 postreply 18:25:27

• 没错，软件里面的逻辑出了问题，一个更新就解决的问题。 -dakinglaile- ♂ (0 bytes) () 09/12/2023 postreply 18:39:42
