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 Goldanalytix GoldScreenCard software as an intuitive analysis tool allows to reliably display

and classify the results. The measured values can be compared to value ranges shown in the

graphical display of the software, which are deposited in the library. This allows a fast and

unequivocal statement within seconds without any need of interpreting the results.

Please read these operating instructions carefully prior to the first use in order to use the

GoldScreenCard properly.

3. Scope of Supply

Your GoldScreenCard set is delivered with the following elements:

In the unlikely event that something is damaged or missing please contact Goldanalytix

immediately (for contact data see page 2).

4. Measurement Principle

The GoldScreenPen utilises the electrical conductance of metals for its measurement principle.

Every metal exhibits a characteristic conductance value, which enables the identification of

falsifications. Due to similar densities, the most used metals for falsifications like tungsten, lead or

tantalum usually differ significantly in their conductivity compared to precious metals or gold

alloys.

The patented, inductive testing method uses low-frequency, electromagnetic alternating fields,

whose penetration depth depends on the applied frequency and the electrical conductance of the

testing sample. The frequency of the GoldScreenPen was adjusted in a manner, that all kinds of

coins are pervaded. Devices currently available exhibit low penetration depths allowing the

determination of layers near to the surface only. Cores of tungsten or tantalum covered with thick,

galvanically plated metal layers can not be identified reliably with those devices.

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

„Goldanalytix_SW“ which is purchased on the USB flash drive. Depending on the weight of the

GoldScreenCard

Manual (this instruction guide)

Small suitcase

coin (e.g. Krugerrand 1 oz vs. ½ oz) different values can arise, although having the same

conductance, due to the high penetration depth of the GoldScreenCard. That´s why the software

differentiates between single coin types.

5. Safety Instructions for optimal Measurement Conditions

The highly sensitive sensor technology and the evaluation unit are stored in the housing of the

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.

Do not use the testing device in the presence of explosive gases, vapours or dust or in wet

environment.

Please operate the device at room temperature and not in proximity of heat sources (e.g.

fan output of your laptop). The measured values are temperature dependant and

linearised by best fit algorithms, but the best accuracy is achieved at room temperature.

Please ascertain that the GoldScreenCard as well as the coins feature the same

temperature, because big temperature difference affects the sensor technology in a

negative manner. The temperature dependency is particularly pronounced among silver

coins

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

process by double-click on the install file „Goldanalytix_Install_Win7.8“ or

„Goldanalytix_Install_Win10“. The install assistant leads you through the setup.

Please note: The install package consists oft wo parts. After having installed the software the

driver will automatically be installed. The driver is necessary for the proper function of the device.

The driver will be installed according to your operating system (Win 7, 8, 10).

Please confirm the following windows for the standard install package. The program usually is

installed in the Windows program folder. If you wish another folder we recommend to change the

directory manually. Afterwards, the install process of the driver will start automatically (CP210x

USB to UART Bridge).

Minimum system requirements:

Windows XP, Vista, 7, 8, 10

USB2.0 port

Hard drive with > 10 MB memory

RAM: minimum 128 MB

Figure 3 –Install window for installing the driver

After installation you will the software in the start menu: [Start]\Programs\Goldanalytix_SW as

well as on the desktop (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. On the basis of deposited reference

values of the library one can check the authenticity of the test specimen.

After starting the software and successful connection of the GoldScreenCard with your computer

the software interface will appear showing the status report "Device Connected" (②,see Figure

4).
