The purpose of initialization in a gold purity analyzer is to mechanically re-adjust the Au peak to 0. Before weighing any goods using the machine scale, you must first re-adjust the peak to 0. Every element possesses a unique spectrum. The difference of each spectrum is displayed at different positions on the X-axis of the software. Hence, you must fix a reference spectrum to 0. The spectrum of other elements will then be fixed. If the Au spectrum is set at 0, the software will identify where the Cu spectrum is, where the Ag spectrum is, and where all other elements spectrum is. If the Au of the machine is not re-adjusted to 0, the machine will give false results.
