Recommended Normal Operating Conditions
The recommended testing temperature is 23°C – 27°C
or 73°F – 80°F. 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 results and performance of
the tester.

as the batteries may corrode, leak or damage the tester.
Batteries should be removed when the tester is expected
to be stored for an extended period of time.

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.
