Diamond Tester, Jewelry Diamond Tester Pen ＋ 40X Mini LED Magnifying, Diamond Selector for Novice, Thermal Conductivity Meter

【TWO-HANDS TEST】 It is essential to perform all tests using two hands - one to hold the diamond and the other to operate the diamond tester. The hand that holds the diamond tester must make contact with the electricity conductive panel on the back of the unit. Testing the diamond with just one hand will result in inaccurate readings.
【INITIALIZATION SETUP】 We have to finish the initialization setup by the following 2 steps: 1st we have to check the detailed room temperature and diamond size,find the Initial value of our test.you can find the detailed table on the back of the diamond tester pen. 2nd we have to turn the wheel to set the Initial value.eg if the size of diamond is small than 0.05ct, and the temperature is more than 30 degrees Celsius,then set the Initial value as 7, it means you have to turn the weel and keep 7 lights on. Otherwise you won't get a acuracy result.
【CAN'T DISTINGUISH MOISSANITE】Please note that this diamond testing pen is designed as an entry-level tool for beginners. It is capable of distinguishing between diamonds and imitation gemstones. However, it is not able to differentiate between natural diamonds and laboratory-grown diamonds (also known as Moissanite).
【FOR DIAMOND】For testing diamond, it will emits beeping-beeping-beeping in a low frequency, 1 time/second. Meanwhile 1-4 pieces of the RED LAMP box of the level meter light on(the bigger the size of the stone is, the more pieces of the red lamp box of the level meter light up)
【FOR IMITATION 】When Testing Imitation stone,such as cubic zirconium ( CZ ), crystal, glass, there will be no sound, and the red lamp won't light.
