GOLDANALYTIX GOLDSCREENSENSOR Bedienungsanleitung Seite 23

By turning the knob, you can select a menu
option and confirm your selection by pushing
the knob. This will take you to the
corresponding submenu.
In order to test your object, please choose
"Measurement mode". As an example, we
have selected 1 ounce of fine gold (Au 999;
nominal value: 44.7 MS/m). Different factors
like embossing depth, fluting, scratches, air
gap, etc. have the effect that the measured
value does not always correspond exactly to
the nominal value. The tolerance ranges can
be found in the conductivity overview on
page 28.
Place the test object from above (see left) as
centered as possible on the measurement
circle ②. This is especially important for
smaller objects that do not completely cover
the sensor coil (diameter of 2 cm.)
The determined conductivity value is
displayed as a number in the upper section of
the display in the unit Megasiemens per
meter (MS/m). The GoldScreenSensor
determines which metal or alloy corresponds
to this conductivity value and displays it
underneath the conductivity value in the
middle of the display (only fine gold and
silver, their alloys and copper). Additionally, a
graphical overview of the conductivity value's
position on the scale of 0-65 MS/m is shown
thanks to a cursor on the scale in the lower
part of the screen. For the metals and alloys
mentioned above, the nominal value is
additionally highlighted in green.
Further (precious) metals and alloys stored in
the device, especially of typical fakes such as
tungsten / tungsten-copper, are displayed in
the section "Additional information" above
the scale in grey letters.
In the case of a counterfeit (e.g. made of a
tungsten alloy), the result could be shown as
in the figure on the left.
