6 Safety level
Every measurement has its tolerance. A typical tolerance of e.g. 5% of the measured
value represents a safety level of 95%. This tolerance is the value by which the
measured value may vary from the real or true value. As in this procedure, two
measured values are compared with each other, it is recommended to use a broad
tolerance.
Factory-provided is this software with a safety level of 95%. This can be overwritten
by any other value.
7 Material Composition
Pure gold bars or coins are rather uncommon. Typically, gold pieces are a composi-
tion of gold and other materials, e.g. to provide a higher stability. That means that
other materials are added in the production process. Common are amongst others:
silver and copper.
The exact composition of the gold piece can be seen in the exposé that typically is
added with bars or coins. Alternatively, this composition can be inquired at the pre-
cious metals separation works, the mint or the refining establishment.
In this window, the composition is to be set in.
