Gently rub the table of gemstone against the
tissue/jewellery cloth and place the gemstone on the
centre of the Test Pad (Fig. 1.8).
To prevent inaccurate readings, replace with new batteries
as soon as the low battery indicator lights up or starts to
blink. A test should not be performed when the battery
power is low or weak.
Batteries do not have to be removed when the AC adaptor
is in use.
Cleaning your gemstone prior to testing
Prepare a clean tissue. Carefully retrieve the gemstone
with tweezers and place the gemstone face down on the
table (Fig. 1.7).
