Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : HMKIS BulletPoint1 : 【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. BulletPoint2 : 【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. BulletPoint3 : 【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). BulletPoint4 : 【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) BulletPoint5 : 【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. BulletPoint6 : 【METAL ALERT】When Testing metal, it will emits beeping-beeping-beeping in a high frequency,5times/second. The thermal conductivity of the metal is very high and can give the same indication as a diamond with most thermal probes.) This Diamond Selector II has a metal Alert Buzzer to warn you when touches metal. If you hear the Metal Alert buzzing sound,re-touch the probe tip so as to touch only the tested stone. BulletPoint7 : 【DON'T WAER GLOVES】When testing, please don't weart gloves. BulletPoint8 : 【CUSTOMER SERVICE】For any questions, feel free to contact us. BulletPoint9 : [WARM NOTICE 4]: We will be always on hand when you have problems.Also you can check the manul.

When testing diamond, it will sound Bee-Bee-Bee in a normal frequency and lights >=9 ,while for other items such as metal,coin,or thers, it will Emits rapid high-frequency beeping.(plz check the vedio) [Intuitive Design]: Fake crystal, such as cubic zirconium ( CZ ), crystal, glass will be no sounds and lights <9. [fast and safe ]: This diamond selector tester designed for quick, precise, and safe diamond testing. No harm to diamonds. [For Diamond] When testing diamond(both real Mosanite and diamonds), it will emits in a low frequency beeping and 1-4 pieces of the RED LAMP box of the level meter light on(the begger the size of the stone is, the more pieces of the red lamp box of the level meter light up) ProductDescription1 : The diamond testing pen is a handy tool used to quickly and easily test the authenticity of diamonds.This diamond testing pen can only help you distinguish between diamonds and imitation gemstones, but it cannot distinguish between natural diamonds and laboratory-grown diamonds. Its working principle is based on thermal conductivity, using the different thermal conductivity speeds to identify whether the sample is a diamond or an imitation gemstone. Diamonds have extremely high thermal conductivity, while other imitation stones do not have such high thermal conductivity. It is important to note that metals also have very high thermal conductivity, so this testing pen cannot be used to test metals. ProductDescription2 : [INITIALIZATION SETUP] After powering on, turn the wheel to keep 4 green lights on to finish the Initialization. Otherwise you will get inaccurate results. All test must be done by two hands, one for hold the diamond and one for the diamond tester. As for the hand which hold diamond tester, you have to TOUCH the electricity conductive panel on the back of the unit. ProductDescription3 : [FOR FAKE STONE]: For fake crystal, such as cubic zirconium ( CZ ), crystal, glass will be no sounds and lights <9.
