9. Testing Loose Stones: Place the
loose stone in the supplied aluminum
loose stone testing plate positioned
with the “culet” facing down into
the recessed hole part of the testing
plate. Then hold the testing plate
steady with one hand, as this will
also allow the electrical current to
pass through your body, permitting
the tester to function as designed
and test properly. While holding the
PRO-D 3 in your other hand, firmly
touch the probe tip to the loose
stone’s “table” (see image) until the
test result it indicated. YOU MUST
FOLLOW THIS PROCEDURE
WHEN TESTING LOOSE STONES
OR THE TESTER MAY NOT TEST
CORRECTLY. DO NOT ATTEMPT
TO TEST LOOSE STONES
WHILE HOLDING THEM IN YOUR
FINGERS OR THE TESTER MAY
NOT TEST CORRECTLY.
10. The probe tip must be cleaned
routinely to ensure proper contact
with the stone being tested. To
clean the probe tip, take a piece
of uncoated white copy or printing
paper and lay it on a table or counter
or other flat surface. Place the tester
in a 90-degree angle to the paper
with the probe tip lightly touching
the paper. Apply enough pressure
