IMPORTANT INFORMATION:
In case of uncertainties, you can also compare the measured values to the conductivity value
tables in the annex of this instruction manual or with other sources (see also Chapter 6:
Evaluation and Interpretation of the Results). In the measurement mode, the device always
displays the measured conductivity value, as well as the material that it MIGHT be.
A 50 Euro cent coin, for instance, has a similar conductivity as the Krugerrand Gold (alloy 916(A),
see on page 28), platinum or palladium. When measuring the 50 cent coin, the
GoldScreenSensor can therefore output Gold 916 as the measurement result, even if it is not the
alloy in question. If one compares dimensions and weight, it quickly becomes clear that no
Krugerrand. The test objects must be at least 0.8 mm to 1 mm thick; blisters and capsules can
be up to 3 mm thick. It is important to always wait 2 to 3 seconds between each measurement
so that the device can calibrate itself. If you place the coins to quickly one after the other, there
may be deviations in the measured values.

In addition, the GoldScreenSensor detects
ferromagnetic objects, which you can identify
by the output "Ferromagnetic" (figure on the
left).
Please note: Within the first five minutes of
operation, it can happen that the displayed
value does not remain constant (whereby a
certain fluctuation of about ± 0.3 MS/m is
normal). In addition, there may be some
fluctuations of the measured values of the
same
object
in
measurements. This is due to the fact that the
coil must first stabilize itself after switching on
the device in order to ensure a homogeneous
magnetic field.
Addition: If the shown conductivity value
seems strange to you, (e.g. you know from
previous measurements that your object is
real and now the device shows a significantly
lower conductivity value), then the device has
probably zeroed itself at this moment. This
happens automatically after a certain number
of measurements. Please wait a short
moment (about 5 seconds) and place your
object again on the device. Now you should
receive the correct result.
By pushing the knob, you will get back to the
