2. Introduction Congratulations on your purchase of the Goldanalytix GoldScreenCard. The Goldanalytix GoldScreenCard is an easy, fast to use and non-destructive testing device for the determination of the electrical conductance of precious metal mouldings. Primarily this device was developed to test the authenticity of precious metal coins without a blister or a capsule, but with restrictions you can use it also for the determination of small ingots made from silver, platinum or palladium.
The sensor technology as well as the evaluation unit is situated inside the compact casing of the device. The GoldScreenCard can be connected to a computer via the integrated USB cable. The signals can be evaluated and compared to reference values of the library included in the software...
GoldScreenCard. Therefore, please be aware of the following hints while performing measurements: Please ensure that the GoldScreenCard does not touch any metallic object or lies on a metallic surface during the measurement because this might lead to inaccuracies of the measurement.
6. Operation and Display Elements The operation elements of the GoldScreenCard are displayed in Figure 1 and Table 1. The GoldScreenCard is ready to use after connecting it to a computer via the integrated USB cable and starting the Goldanalytix software.
7. Installation of the Goldanalytix Software Before you are able to use the GoldScreenCard you have to install the Goldanalytix software via the purchased USB flash drive as well as the driver. Therefore, please connect the USB flash drive with your computer and start the installation...

(as icon, when you did not deselect this option during the installation process). The software will automatically start after installation. In case of the GoldScreenCard is not being recognized, please exit and restart the software.
8. Description of the Goldanalytix Software Please be aware that you can use the GoldScreenCard in its full range of functions only with the purchased Goldanalytix software. Operating without the program package is not possible. On the one hand, the software graphically displays the measured values in a diagram, on the other hand, it offers access to the library containing conductance values.

The given sensor value should be in the range of about zero. In case of the given value is <20, please repeat the calibration process. When the GoldScreenCard is placed nearby a laptop or a magnetic balance, please do not move it after calibrating.

By touching the "TEST" button of the GoldScreenCard measurements are performed in short time lags (ca. 0.5 seconds each). The corresponding value immediately appears in the diagram as a pursuing blue line (⑥, Figure 7) as well as numerical value in the information bar „Messwert“...

Krugerrand. Figure 8 – Classification of measurement results As already described in the sub-chapter 'Measuring with the GoldScreenCard' the diagram does not only show a value line as reference value for a certain coin but a green-shaded values range.

Goldanalytix library. We recommend to do so in order to get the same file structure for a better overview. The new value is stored automatically in the user library and can be selected through LIBRARY ->...
9. Overview of Conductance Values We would like to point out that the GoldScreenCard is specifically designed for measuring conductance of in the library deposited coins (alloy, thickness, embossing), which can be extended by the user through deposition of own values. The purpose of the following table is to serve as reference value for the classification of common coin metals.
