Remove the battery cover and insert 3pcs of AAA batteries
into the battery compartment correctly with the direction of
positive and negative pole. Turn the power ON/OFF switch
to "ON", the READY lamp will blink. Then wait for about 25
seconds for the testing probe to be heated. The tester is
ready for testing when the green lamp lights up.
• Use a gem cloth to clean the stones to be tested. When
the testing is conducted in a room with high humidity, it is
better to scratch the tester's probe tip on a dry cloth for
several times.

hand; For loose stone, you are required to place the stone
on the Testing Base, and hold testing base with one hand.
