Press the "SET" key to modify the setting parameters and press the "ENTER" key to exit the setup mode.



Test index

D-G pure gold test


Gold ratio /K value / density / volume

D-K K gold test


K-1 gold + copper /K-2 gold + copper + silver /K-3 gold + silver / density / pure gold ratio / volume)

D-P platinum / platinum determination


Purity / density value / volume

D-A alloy test


Percentage / density / volume of main metal
