How to Use Diamond Tester Pen
how to use diamond tester
- Remove protective cap and connect the USB Power Cable, then POWER light on.
- Choose the correct diamond size by adjust the wheel, test when the READY light on
- When testing an S diamond continuously, the S diamond needs to cool down for a while before testing.
Choose the right size. if don't know, choose M.

S-Mode is extreme sensitivity
- Built for Micro-Diamonds & Tiny Gemstones.
- Detects even the smallest stones that normal testers miss.

- If you don't know the specific size, you can use M first.

L-Mode is large diamond specialist
- Optimized for 1+ Carat Stones & Heavy Jewelry.
- Filters out minor environmental interference for rock-solid accuracy on large gems.
- the device will display incorrect results when testing small objects
- If you don't know the specific size, you can use M first.
Usage steps

Testing S size Diamond
- Comfirm: the size of the diamond is " S"
- Adjust the wheel to the CORRECT SIZE
- Level Meter =9 lights and emits sound

Testing L size Diamond
- Comfirm: the size of the diamond is " L"
- Adjust the wheel to the CORRECT SIZE
- Level Meter =9 lights and emits sound
Why do I get diamonds in almost everything I test?
The device is set to the wrong setting. The S setting is the ultra-sensitive setting and can only be used to test Micro-Diamonds. This setting will cause false readings if it is used to test objects weighing more than 0.2 grams.
Why does my device barely respond when I test diamonds?Why not work?
The L setting is specifically designed for large diamonds. If you use this setting to test small diamonds, the device will barely react.
What should I do if I don't know the exact size of the diamond?
You can start by testing with the M setting. The M setting is for testing diamonds between 0.5 and 1 carat.
Precautions

Working environment requirements
- The working environment temperature is preferably between 5-35?
- Need to be in a windless environment

- 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

Unable to tester too 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

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.
