Wear it on your finger for about 30 seconds.
Different colored numbers will appear in the black part of the ring.
1. Why doesn’t it show the temperature?
Answer: Because there is a process of heating up and cooling down, the temperature will also be sensed with the change of the environment (the environmental temperature is low in winter, and the hands are cold). The temperature sensing test paper inside the ring can only display the temperature when the hand temperature reaches a certain temperature. (When it is not displayed, you can cover it with your other hand for a while.)
2. Why do I wear it to display multiple temperatures?
A: Because the temperature is unstable, multiple temperatures will be displayed. It is recommended to wear it for a while, after a long time.
Only the number of your hand temperature will be displayed. (If there are multiple colors, the green display shall prevail. Is your hand temperature)
3. Why is the temperature not particularly accurate?
A: Jewelry is an ornament, and it can’t be compared with professional thermometers in terms of functionality.
It’s not like our mercury thermometer, which can only come down if the temperature goes up.
This temperature varies with the hand temperature)
