If batteries are used (3 x AAA batteries), take note of the positive (+) and negative (-) directions of
the batteries when inserting the batteries into the tester (Fig. 1.2). The use of alkaline batteries is
preferred, as it should generally give approximately two and a half hours of continuous operation,
while the use of ordinary batteries will give a shorter working life.

The recommended testing temperature is 18oC - 27oC or 65oF - 80oF Please allow the gemstone or
jewelry piece to adjust to room temperature prior to testing. Exposure and/or operation of the tester
outside the room temperature would affect the result and performance of tester.
The probe tip must be placed at the right angle or perpendicular to the facet of gemstone for an
accurate reading.
Tests should be conducted on the table of the gemstone. In the event of any doubt, kindly test on
the girdle of the gemstones instead.
To achieve optimum accuracy for tests involving very small, it is important to allow the gemstone
to cool down before subsequent tests.
Prepare clean tissue / jewelry cloth. Carefully retrieve the gemstone with tweezers and place the
gemstone face down the table (Fig.1.8).
