Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : HMJOY BulletPoint1 : [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. BulletPoint2 : [TWO HANDS OPERATION] 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.If you test the diamond just by one hand, you will get a wrong result BulletPoint3 : [CAN'T DISTINGUISH MOISSANITE]: This diamond testing pen is just a entry-level pen for amateur. So it can only help you distinguish between diamonds and imitation gemstones, but it cannot distinguish between natural diamonds and laboratory-grown diamonds (Also Called Moissanite). BulletPoint4 : [FOR DIAMOND]:For testing diamond(include real diamond and Moissanite), it will emits beeping-beeping-beeping in a low frequency, 1 time/second. Meanwhile lights ≥ 9 (Notice: the bigger the stone is, the more lights on) BulletPoint5 : [CAN'T TEST METAL]: Please never use this diamond testing pen test metal! BulletPoint6 : [WARM NOTICE 1]: Please make sure the ambient temperature is not lower than 10 degrees Celsius when in use, and shut down promptly when not in use. BulletPoint7 : [WARM NOTICE 3]:The contacts need to be pressed vertically against the surface of the diamond. BulletPoint8 : [WARM NOTICE 3]: Don't wear gloves when you have a test BulletPoint9 : [WARM NOTICE 4]: We will be always on hand when you have problems.Also you can check the manul.

But you are worried about how to identify the authenticity of jewelry. Hqdz-td diamond tester is an electronic instrument designed and manufactured according to the thermal conductivity of diamonds to identify the true and false diamonds. It can also be used for testing sapphire, ruby, crystal, agate and other stones. Our diamond tester solves your problem perfectly.
How To Test Diamond: Turn on the switch. Make sure only 1 light is lighting up on the scale.
Wait few seconds for the probe to heat up until Lamp on ready OK. Turn on the lights numbers corresponding to the indoor temperature and diamond weight. If don't know, Set 4 lights is lighting up on the scale. Start test diamond, no need to adjust the switch switch. Use the diamond discriminator probe to make 90-degree contact with the measured object, and observe the indicator light change. It needs a little bit of force to stop it on the diamond surface and make full contact. If unsuccessful, please repeat the second step.

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.
