2.4 Important Notes
about Performing a test
• Ensure your tested gemstone does not exceed 5 mm in height and
its width covers the Photo-detector completely. The carat equivalent
of this is approximately 0.02 to 10 carats.
• Conduct prior supporting tests to ascertain the stone for testing is
a diamond.
• Only open-back mounted jewelry can be tested.
• To ensure accuracy, it is recommended to place the gemstone in at
least four different positions on the testing area and to check if the
readings are consistent.
• Ensure the testing platform and photo-detector are free of dirts and
dust for a reliable testing result.
• To prevent inaccurate results, no test can be conducted when the
Power button turns red, indicating low battery.
• You can only conduct a test when the "Start Test" button is lit in
blue.
• A test is completed when the "Start Test" button stops blinking and
is lift in white.
• To reset and start a new test, press the "Start Test" button so that
the button light reverts to blue light.
