1. Install the battery, turn on the power indicator; After a while, the preheating indicator will light up!

2. When testing, set the tri-color indicator to the fourth grid, then press down on the triangular iron plate at the back with your hand and align the probe vertically with the object being tested. If it is a diamond, the light will move to the ninth grid or above, i.e., the red light zone, and a dripping sound will be emitted.

3. If you are testing jade, the light will illuminate on the fifth or sixth grid, indicating that the jade has reached its hardness, and no sound will be emitted.
