How to use diamond tester: 1.Don't wear gloves,Don't detect metal,Best to measure in no wind conditions.The operating temperature is within the range of 10-35 degrees Celsius, and the humidity is below 80%,When testing diamond, your right index finger must keep touching the metal panel on the back of the tester. 2.Diamond Tester Install Battery,Put the 9V battery in(incloud).Table Initial Value.Turn on the switch.Wait few seconds for the probe to heat up until Lamp on ready OK. 3.Set Initial Value,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. 4.Vertical Contact,Use probe to make 90-degree contact with the measured object.It needs little force to stop it on the diamond surface and make full contact. 5.After use, turn off the power.If unsuccessful, please repeat the second step. Popular among professionals, hobbyists, jeweller enthusiasts, and business owners alike. Excellent tools. Excellent Value. Great gift idea.

♦[Intuitive Design]Our diamond tester features an LCD display and LED indicator make it easy to read your precise testing results.No need for a professional - the Hqdz-td Diamond Tester Pen is easy to operate. Just turn it on, lightly press the tip to the gemstone, and wait for the beep to know if it's real or fake.

♦[If it's Real Diamond]The professional Diamond Tester will lighted up over 9 and emits audible sounds. No reaction means the stone is a fake crystal or simulant like cubic zirconium (CZ).

♦[Bare Hands Operation]All the tests must be done by your bare hands. If you put on your gloves, the metal alert will not function since a normal moisture levelof your hands is necessary for 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.

♦[Beeping Upon Startup]Ensure correct installation and adequate power in the test pen battery. Also, clean the test pen probe as maintaining its cleanliness can enhance testing efficacy.A beeping sound upon powering on signifies the need for initialization settings. Consult the table on the rear of the machine for the specific initialization settings considering the diamond's temperature and size. Adjust the initial number of illuminated lights by rotating the knob (the default setting is to have 4 lights illuminated at room temperature).

♦[High-Frequency Sound when Testing Metal]The high-frequency sound during metal testing is due to the test pen's operational principle, which relies on thermal conductivity to distinguish between diamonds and fake gemstones. Since metal possesses thermal conductivity similar to diamonds, it generates a high-frequency sound during testing.

♦[Professional Diamond Selector]After powering on, turn the wheel to keep 4 green lights on to finish the Initialization. Otherwise you will get inaccurate results.For Diamond Simulants：No Sound and No Red lamps light on.[Note] This diamond tester cannot distinguish Mosanite and diamonds. Because the product works by measuring the thermal conductivity of an object. The thermal conductivity of Mosanite is almost the same as diamond.
