2.3 Important Notes
about Performing a test
• Ensure your tested gemstone does not exceed 6mm in height and
its width covers the Photo-detector completely. The carat equivalent
of this is approximately 0.1 to 6 carats.
• Conduct prior supporting tests to ascertain the type of red stone for
testing.
• Only open-back mounted jewelry can be tested.
• Rough, unpolished stones may not be able to test with accurate
results.
• Opaque or translucent stones, and stones of dark red shades may
not be able to test with accurate results.
• The tested gemstone or jewelry will need to be secured against the
Photo-detector by adjusting the light source directly onto the tested
stone or jewelry.
• To enhance accuracy, it is recommended to place the ruby
gemstone in at least 4 different positions on the Photo-detector and
checking if the readings are consistent.
• 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 pressed
and is lit in blue.
• A test is completed when the "Start Test" button stops blinking and
remains stable and lit in white.
• To reset and start a new test, press the "Start Test" button to return
it to be lit in blue.
