Why do I get diamonds in almost everything I test?

The device is set to the wrong setting. 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.

Why does my device barely respond when I test diamonds?Why not work?

The L setting is specifically designed for large diamonds. If you use this setting to test small diamonds, the device will barely react.

What should I do if I don't know the exact size of the diamond?

You can start by testing with the M setting. The M setting is for testing diamonds between 0.5 and 1 carat.
