PMV PRO Functions
The PMV PRO uses up to four different measurements to determine if a coin or bar is
consistent with genuine precious metals.
The four measurements are:
1.  The PMV PRO measures the sample’s resistivity just under
the surface of the metal. This ensures there are no contaminants or foreign metals in
or near the surface.
2. Using the sensors above and below the sample, the PMV PRO measures
the sample’s bulk resistivity. This measurement checks the entirety of the sample
and ensures there are no contaminants or foreign metals anywhere between the two
sensors.
3.  The PMV PRO electronically measures the thickness of the
sample using the average thickness of the face of the sample.

the sample is the correct density. The user must enter the measured weight of the
sample to perform this test.
