Place the bare diamond to be tested into the appropriate receed hole on the support tray, with the table face up. Those already inlaid do not need to put holes in the tray, you can grab it by hand. 3. Move a few bright LEDs according to the weight of the diamond to be measured and the temperature. 4. Lower the needle , hold the instrument, and the index finger of your right hand touches the conductive plate on the back cover of the instrument. Make the probe vertical and lightly touch the table of the diamond to be measured. 5. Carefully observe the instrument. If the rest of the light-emitting diodes reflect yellow, then when the light-emitting position moves to 9 diodes with a buzzing sound, this indicates that the test is a real diamond. Conversely, if there are nine diodes in a place with insufficient light, and there is no beep, then it means diamonds.
