conductivity value (the nominal value for pure
gold and silver and their alloys, as long as
these are no summarized ranges [e.g. silver
900/925] is shown in round parantheses next
to the established alloy) and visualizes it
underneath the conductivity value in the
middle of the display (only pure gold and
silver, their alloys and copper). Additionally,
you will have a graphical overview of the
conductivity value's position on the cale of 0-
65 MS/m thanks to a cursor on this scale in
the lower part of the screen. For the
aforementioned metals and alloys, the
nominal value is additionally tinted in green.
The device also stores further (precious)
metals and alloys (especially of typical fakes) –
e.g. platinum, tungsten, tungsten-copper –
but these are only shown in the section
"additional information" in the zone over the
scale in grey letters. With the exception of
platinum and palladium, whose conductivities
lie within the range of gold 900, the respective
ranges will not be tinted in green. If they do
not lie within the range of a precious metal or
a precious metal alloy, the display will not
show any visualization in the centre under the
conductivity, either.
In case of a falsification (e.g. made of a
tungsten alloy), the result could be shown as
in the image on the left.
Additionnally, the GoldScreenSensor detects
ferromagnetic objects, which is visualized by
the display of "Ferromagnetic" (image on the
left).
Please keep in mind: Within the first five
minutes of the device's operation, it may
happen that the shown value does not stay
stable (although a certain fluctuation of about
± 0.3 MS/m is normal). Additionally, especially
in this period, there can be certain
fluctuations of the measured values of the
same object in several consecutive
measurements. This is due to the fact that the
coil first has to stabilise itself after switching
the device on to guarantee a homogeneous
magnetic field.
