The S setting is the ultra-sensitive setting and can only be used to test Micro-Diamonds. This setting will cause false readings if it is used to test objects weighing more than 0.2 grams. **Q: Why does my device barely respond when I test diamonds?Why not work?** A: The L setting is specifically designed for large diamonds. If you use this setting to test small diamonds, the device will barely react. **Q: What should I do if I don't know the exact size of the diamond?** A: You can start by testing with the M setting. The M setting is for testing diamonds between 0.5 and 1 carat. ## Customer Reviews ### ⭐ Don’t buy *by K***K on 1 June 2025* Don’t buy ### ⭐⭐ Misleading customers. *by M***H on 13 July 2023* In the picture they show hmkis thermal conductivity pen + 60x manfying monocular.
