In life, if you encounter a body fat scale and can't weigh your body fat, you don't have to worry about whether this thing is broken or not. Although this body fat scale is an electronic product, it won't break down so easily. It may be that the battery at the bottom is loose because I often run into the body fat scale, so I can't detect this number. So if you restart the computer or reinstall the battery, this problem may be solved.
There is also a body fat scale that can be called body fat, but you will find such a problem. This number has been flashing, up and down. If you weigh it again, the number displayed is different from the last time, so you can tell you without a doubt that the battery needs to be replaced, which does not mean that the body fat scale is broken.
The last thing you encounter is to combine the two methods mentioned above. If your body fat scale can't weigh body fat, you should first choose to reinstall the battery. If it still doesn't work, you should choose to replace the new battery. If the result is still not good, this result can only tell you, maybe there is something wrong with your body fat scale, and you need to call the after-sales service at this time. I hope these skills will help you.
