How to test gems
-Turn on.
-Make sure only 1 light is on on the scale.
-Wait a few seconds for the probe to heat up until the light comes on normally.
-Turn on the light that corresponds to the room temperature and the weight of the diamond.
-If you don't know. Set 4 lights to light up on the scale.
Start the test diamond without adjusting the on/off switch.
-Use the diamond discriminator probe to make 90-degree contact with the object under test, and observe the change of the indicator light.
-It takes a little bit of force to make it rest on the surface of the diamond and make full contact.
-If it fails, repeat step two.
