IV. IMPORTANT NOTICE

•    Due to the testing methodology, this tester is not 

     intended to test for any colored diamonds, such as      

      blue and black diamonds, as the electrical conductivity 

     of these colored diamonds differs from colorless 

     diamonds.

•    Keep the tester dry. Precipitation and all types of 

     liquids or moisture can contain minerals that will 

     corrode electronic circuits. If your tester gets wet, 

     remove the battery, and allow the tester to dry 

     completely before replacing it. 

•    Do not use, store or expose the tester in dusty and   

     dirty areas. Its moving parts and electronic 

     components can be damaged. 

•    Do not use, store or expose the tester in hot areas. 

     High temperatures can damage or shorten the life of 

     the tester , damage batteries, and warp or melt certain 

     plastics. 

•    Do not use, store or expose the tester in cold areas. 

     When the tester returns to its normal temperature, 

     moisture can form inside the tester and damage 

     electronic circuit boards. 

•    Do not attempt to open the tester other than as 

     instructed in this handbook. 

•    Do not drop, knock, or shake the tester. Rough 

     handling might break internal circuit boards and fine 

     mechanics.

•    Do not use harsh chemicals, cleaning solvents, or 

     strong detergents to clean the tester. 

•    Do not paint the tester. Paint can clog the moving parts 

     and prevent proper operation. 

If the tester is not working properly, kindly contact
