GOLDANALYTIX GOLDSCREENPEN Bedienungsanleitung Seite 30

Calibrating the device:
Calibration of the GoldScreenPen is not necessary and cannot be carried out by the user. The
device is supplied factory-calibrated and ready for immediate use.
Changing the system language:
Follow the "Language selection" in the main menu by pressing the rotary knob. You can now
select your desired language. You will then automatically return to the main menu.
Restarting the device:
If the device no longer responds to the usual operation and can no longer be switched off, you
can restart it using the reset button. The reset button is located next to the charging socket (see
illustration on page 23). Use for example a bent paper clip to press the reset button. The device
will switch itself off. You can then restart and operate the device as usual.
6 Evaluation and Interpretation of the Results
Below you will find important information on how to interpret the determined conductivity
value. Please note that the device only measures the electrical conductivity inside the test
object. To the conductivity values, corresponding precious metals and alloys, as well as typical
counterfeit materials, are assigned in defined tolerance ranges. Your task is to check whether the
displayed values correspond to the expectations for your test object. An example: For an object
made of fine gold, Gold 999(+) must be displayed. Any deviation indicates a possible counterfeit.
If the device displays e.g. Gold 900 for this object, this does not mean that the object is made of
Gold 900 instead, but that it lies outside the correct conductivity range and therefore shows
irregularities. Please refer to the conductivity overview in the appendix for additional reference
values.
IMPORTANT: A correct conductivity value alone is of course no guarantee that your object is not
a fake. This is because an alloy that has the same electrical conductivity as gold or a gold alloy,
for example, can definitely be produced (e.g. silver-copper alloys). However, in such a case, the
dimensions or weight of the coins and bars are usually not correct. After all, it is relatively easy
to imitate one physical property (conductivity, density, sound, etc.) of a precious metal. To
imitate two or more physical properties at the same time, however, is more difficult or almost
impossible. Therefore, if the conductivity is the same, another physical property such as density
will not match. We therefore strongly recommend the use of several testing methods in order to
exclude counterfeits with certainty. This is because no single non-destructive method for testing
precious metals can detect every type of counterfeit on its own.
The following procedure is recommended for typical bullion coins:
1. Determine the weight using a precision balance: Does the determined weight
correspond to the target weight?
