• [Beeping Upon Startup]:Ensure correct installation and adequate power in the test pen battery. Also, clean the test pen probe as maintaining its cleanliness can enhance testing efficacy.A beeping sound upon powering on signifies the need for initialization settings. Consult the table on the rear of the machine for the specific initialization settings considering the diamond's temperature and size. Adjust the initial number of illuminated lights by rotating the knob (the default setting is to have 4 lights illuminated at room temperature).
• [High-Frequency Sound when Testing Metal]:The high-frequency sound during metal testing is due to the test pen's operational principle, which relies on thermal conductivity to distinguish between diamonds and fake gemstones. Since metal possesses thermal conductivity similar to diamonds, it generates a high-frequency sound during testing.
• [Simple to Use]:Diamond Tester Pen is simple to operate to get results, professional(s) are not required. Simply turn on our Diamond Tester Pen detector; place the tip of the Diamond Tester on the gem stone (lightly pressed is sufficient) and If the stone is fake, crystal or cubic zirconia, the tester will not beep.
