Start Your Fix Here. Quick Fix: Top 4 Issues & Solutions Question 1 : When testing a metal ring or finger, the tester keeps beeping—Is it broken? Answer 1 : No defect! This diamond tester is only for gemstone diamond testing. Non-diamond items like metals and fingers have thermal conductivity similar to diamonds, so beeping during testing is a normal phenomenon—just test gemstone diamonds. Question 2 : The tester beeps as soon as it’s turned on, without touching any gemstone—How to fix it? Answer 2 : It’s most likely the wrong indicator gear! Adjust the indicator from "max gear" back to the "4th mark", turn off the tester and restart it—the beeping will stop. Then test according to the standard steps. Question 3 : After following the steps, the tester doesn’t light up or beep—What to do? Answer 3 : First check two small details: 1.Did you hold the triangular metal plate on the back? (The circuit won’t conduct if you release it); 2.Did you preheat it for 30 seconds? (A cold sensor can’t detect) Fix these two points, and it will work normally. Question 4 : When testing the same diamond, the result is different every time—Why? Answer 4 : It may be due to the probe angle or waiting time! Align the probe vertically with the diamond (don’t tilt it), and wait 2 seconds for the sensor to read the data. Slow operation will give a stable result.
