    Merchant Video

    1. Remove protective cap and connect the USB Power Cable, then POWER light on.
    2. Choose the correct diamond size by adjust the wheel, test when the READY light on
    3. After testing, you need to leave the diamond on the table to cool for a few minutes before the next test.

    How to test metals

    diamond tester

    One-handed operation ( Wrong )

    • One-handed operation of equipment cannot determine whether an object is metal by its electrical conductivity
    • As long as it absorbs heat fast enough, it will be misjudged as a diamond

    diamond tester

    Two-handed operation ( Correct )

    • Operate with both hands, and the device removes metal through conductivity. The light strip flashes double.
    • The left hand needs to touch the object and the right hand needs to touch the metal plate on the back of the device

    Testing S size Diamond

    1. Comfirm: the size of the diamond is " S"
    2. Adjust the wheel to the CORRECT SIZE
    3. Level Meter =9 lights and emits sound

    Working environment requirements

    • The working environment temperature is preferably between 5-35?
    • Need to be in a windless environment
    • Do not get close to hot or cold objects

    Pre-test preparation

    • Both the diamond tester and the diamond need to wait for more than 1 minute. Do not hold the diamond in your hands (your hands are hot)
    • There should be no water, grease, etc. on the diamond surface

    Functional limitations

    diamond tester

    Unable to tester small diamonds

    • When the diamond size is less than 0.025ct, the diamond tester light bar cannot reach the red area
    • When the diamond size is less than 0.015ct, the diamond tester light bar will not respond

    diamond tester

    Unable to distinguish moissanite & diamond

    • This diamond tester cannot distinguish between moissanite and diamond
    • The device can only judge thermal conductivity through heat transfer, and the thermal conductivity of the two is close.

    60X Jewelry Loupe Magnifier

    • Material: ABS pocket microscope.
    • Size: 3.5 x 4 x 2 cm coin magnifier.
    • Illuminated by LED. Bright LED light of the Magnifying Glass provides enough light at any dim conditions currency detecting microscope.
    • Compact design provides 60X magnification magnifier for currency.

    Troubleshooting Methods

    1. After turning on the machine, the light strip is full of lights, or there are too many lights, or the number of lights changes back and forth

    • It might be that the battery power supply voltage is low or fluctuates. Please switch to USB power supply and try again.
    • It might be due to the low ambient temperature that the temperature at the head of the equipment has not been heated to the theoretical required temperature. Please let it stand for a while. It will gradually return to normal.

    2. Test the metal full lamp and determine if it is diamond

    • This device can distinguish metals from diamonds by the conductivity of the objects. However, users need to operate with both hands to determine whether an object conducts electricity, whether it is metal or diamond

    3. The device did not respond when testing the diamond

    • Perhaps the diamond size is too small. When the diamond size is less than 0.015ct, the diamond tester light bar will not respond
