Note that the switch also controls a row of lights. When the switch is pushed slowly, the row of lights will rise one by one. For diamonds, a row of lights is on for 1-2 grid measurement, the right hand is holding the instrument, the hand should touch the stainless steel behind, and the left hand is holding the diamond (it needs to conduct electricity by the hand, and the result is wrong if it does not conduct electricity). Press in the middle of the diamond. If the diamond is measured, a row of lights will rise to the red light, and there will be a "drip" sound. The voice of the fake diamond is fast, but the light will not rise. Any metal will make a sound when it touches the probe. The sound is different from that of the real diamond. The sound of "Didi" is faster.
