Introduction

Congratulations on your purchase of the Goldanalytix CaratScreenPen. The Goldanalytix CaratScreenPen is an easy-to-use and non-destructive testing device for the determination of purity/carat number of gold alloy surfaces in jewellery and other precious metal objects.
Goldanalytix, established in 2012, is the leading provider of precious metal testing methods in Germany. With the CaratScreenPen, we offer a testing device, which establishes the fine content on the surface of gold jewellery, scrap gold and other auriferous material by means of an electrochemical measurement method. In addition, it can be determined whether platinum, palladium or rhodium-plated surfaces are present. The measurement method is based on the fact the pen probe creates a so-called “galvanic cell” when in contact with the testing object on the measuring surface, and through the resulting voltage drop the corresponding carat number is determined.

By the way: On our homepage at www.gold-analytix.com you will always find the latest version of the instruction manual, so that you can keep up to date with new types of forgery and findings around precious metal testing.
Important note on the optics of the probe pen and measuring surface: Every probe pen is tested for quality in connection with the device, which leads to a slight discoloration of the probe tip. This is not a lack in quality, but only a guarantee that your device was checked before delivery. Due to technical production reasons, the measuring surface can show creasing, slight scratches or traces which cannot be avoided. This does not affect the measurement in any way.

Remove such residues with the enclosed glass fibre pen and a damp cloth prior to measurement.

Safety instructions for the electrolyte solution

CAUTION! The electrolyte solution contained in the probe pen causes skin irritation, as well as severe eye irritation. Read the following safety instructions carefully. For more information, request the Safety Data Sheet of the electrolyte solution from Goldanalytix.

• Due to transport, it is possible that some electrolyte solution my leak out of the probe pen before the first use or that a larger amount of liquid leaks out during the measurement. Simply clean the probe pen with a dry paper towel and dab the probe tip carefully several times to eliminate the liquid leakage.
• Close the probe pen with the cap after each use. If the probe pen is stored open for a longer period of time, the probe tip may dry out and the electrolyte solution may crystallize. This impairs the functionality of the probe pen and the probe pen must be replaced.
• If the electrolyte solution comes into contact with your eyes, rinse your eyes gently with water for a few minutes and, if possible, remove any contact lenses. If the eye irritation persists, seek medical advice and have the label at hand.
• Keep the electrolyte solution out of the reach of children.

Preparing measurements / Using the glass fibre pen

IMPORTANT INFORMATION
Many gold alloys, especially objects with a lower carat number, are covered with a more or less strong oxide layer after a certain amount of time, which shows itself in the form of e.g. greyish, brownish or black deposits on the surface. To ensure uniform and objective measurement conditions, you must always remove the oxide layers and also other contaminants such as fingerprints, grease residues or other soiling with the enclosed glass fibre pen and a damp cloth.
To do this, place the glass fibre pen on the desired area and carefully polish the object under light pressure until a color difference is visible. Then place the probe tip on the polished area. If a testing object is measured with the CaratScreenPen, also slight discolorations may remain on the object. This can be observed especially on objects with a very high silver content (black spot) or copper content (copper-colored spot). The discoloration is caused by the electrochemical measurement process of the CaratScreenPen. You can polish the discoloration with the glass fibre pen and thus remove it. Please keep this in mind when measuring mint or representative objects, and ideally measure in inconspicuous places. Especially with supposed 8 or 9 carat objects, it is almost essential to clean the desired measuring area with glass fibre pen beforehand. If the result deviates from the hallmarking on the object or if the measurement result is output in one of the transition ranges, it is advisable to use the glass fibre pen and perform another measurement.

Calibrating the device
Regular calibration is necessary to ensure accurate measurement results!

| You can access the calibration mode either via the main menu (select “Calibration”) or in the measuring mode via “CAL”. Before each use and after each restart, the device must be calibrated with the integrated calibration piece ③ made of 14 carat (585) red gold.

Pre-treatment of the calibration piece with the glass fibre pen is important to obtain an optimal result. Oxide layers and other impurities could falsify the calibration and lead in the following to incorrect results. Therefore, clean the calibration piece with the glass fibre pen before each calibration. It is also advisable to wipe the calibration piece with a soft, damp cloth after polishing. Please always carry out these steps, even if you do not directly notice any impurities on the surface.

Make sure that the probe pen is inserted correctly and all the way into the socket ④. Now you can place the probe tip as vertically as possible on the calibration piece. Calibration starts automatically (figure on the upper left). Keep the tip on the calibration piece until the blue-gray progress bar has run through. If calibration is successful, a green bar appears with the output “OK” (figure on the lower left).

****| If the calibration should fail, a red bar with an “X” appears (figure on the left). In this case, please clean the calibration piece again and repeat the calibration. Should the calibration fail again, restart the device and try another calibration process. If you have a second probe pen, try the calibration with this one. If those measures do not lead to success, please contact us.

Performing measurements

| ****

For testing your objects, select the “Measurement mode”. The “READY” display shows you that the device is ready for measurement. Please not the important information below before taking the first measurement.

If the device does not show any reaction when you put on the probe pen, it is either a connection error (check the cinch cable!) or a varnished object.

To perform a measurement, place the testing object on the golden measuring surface ②. It is extremely important that there is an electrical contact between the gold surface and the testing object: Therefore always touch with the metal and not, for example, with stones or other non- conductive materials. With the other hand, place the probe pen on another conductive part of the testing object. Press lightly and the measurement will start automatically – you will see “Measurement in progress…” (figure on the left). Wait until the measurement is completed.

The result is output in the form of 3 indications ( figure on the lower le ft): The yellow-orange cursor

(A) flashes on the measurement scale in the carat range of the test object. In addition, the carat number is output in the unit “K” ( B e.g. 14K for 14 carat) and below the respective range of the gold content in percent ( C ). Furthermore, for some result screens, another line with additional information ( D ) is shown.

| After the measurement, the result remains for a few seconds. Then the screen display changes back to “READY”. However, you do not have to wait, but can directly test the next object once the result is logged in.

In the lower section of the display, you can either return to the main menu by pushing the control knob or switch directly to calibration via “CAL”.

---|---

IMPORTANT INFORMATION
We recommend filing the testing objects before measurement. The CaratScreenPen analyzes only the surface of the testing objects. A penetrating measurement, i.e. an examination of the core of the respective objects is only possible if you file the object. But even without filing, many fakes can be detected and cheap, only lightly gold-plated costume jewellery can be distinguished from valuable gold jewellery.
The pen of the CaratScreenPen contains an aqueous electrolyte solution with a pH value of 5.8 (slightly acidic). Due to the limited volume, the pen has a certain lifetime. Below a certain liquid level, a reliable measurement can no longer be guaranteed. Should you notice deviating values or errors during calibration, you should replace the pen: This is usually only the case after circa 4000-5000 measurements.
Please note the following special cases. Detailed information on the individual special cases can be found on our website at www.gold- analytix.com/caratscreenpen.
Be especially careful with jewellery without a hallmark. Objects should always be hallmarked to the correct gold content. Therefore, unmarked objects are often fakes or only lightly gold-plated costume jewellery. In addition, you have no indication of the alloy or the gold content of the object. Therefore, be particular careful when interpreting the measurement results. For jewellery without a hallmark, we recommend intensive treatment with the glass fibre pen or filing of the object. If the CaratScreenPen shows a gold content in the range of 21-24 K, it is probably only a gold coating and not an object made of fine gold. But also with unmarked objects with a lower carat output, you should be careful and take several measurements. Please keep in mind that also marked objects can of course be under-alloyed!
Another special cased are objects which below their surface are made of a gold ally and are also hallmarked accordingly, but have been plated with a thin gold layer for aesthetic reasons. This often happens, for example, with 585 gold coins – by polishing those objects with the glass fibre pen, you can remove the superficial layer and thus quickly and easily determine the “true” alloy. Please note, however, that the color differences between the treated area and the surrounding area are sometimes very noticeable.
For white gold objects, the technique of rhodium plating is often used. This involves applying a very thin layer of the very expensive precious metal rhodium to the finished piece of jewellery. When the object is measured, the CaratScreenPen will output the measurement result in the blue range of platinum/palladium/rhodium. Treat the object with the glass fibre pen to remove the rhodium layer and get the correct measurement result. However, be sure to note that for objects made of platinum (950, 999) or palladium (950), the correct measurement results are in the blue range.
Jewellery pieces may be coated with a protective lacquer to protect them from environmental influences. Should you wish to measure an object with a protective lacquer coating, the device will not show any reaction when the probe pen is placed on the surface. This is due to the non-conductive protective varnish, and therefore the device will not receive an electrical signal. Remove the thin layer of protective varnish by lightly polishing with the glass fibre pen and perform the measurement on the polished area.

Changing the language

Evaluation and Interpretation of the Results

In the following, you will find information on the interpretation of the measurement results. The CaratScreenPen measures the gold content on the surface in a reliable way and with high accuracy within the physical possibilities. However, depending on the alloy composition, other precious metals that might distort the measurement result may also be present. Therefore, in the following section you will find some examples in order to explain the different result screens. The most important step, however, is to classify the respective piece of jewellery by checking the hallmark. This is because in most cases, you will want to verify whether an object actually corresponds to the hallmarked gold content.

Black Measurement Range

|

If the cursor flashes in a black measurement range, it is very likely that the object has a gold content in the indicated range. For example, the result “8K” indicates that the object has a surface gold content between 30.0 and 35.4%. As a rule, the CaratScreenPen indicates the range of the carat number 2.1% in the measurement result. Exception: 8 K = 333‰ or 33.3% gold content.

Transition Measurement Range

| If the cursor flashes in a light gray measurement range (so-called transition range), the gold content of the object cannot be clearly assigned. In this case, for example, the result in the figure on the left indicates that an object with a 14 carat hallmark could have a high silver content and therefore reach into the 18 carat range, although the gold content actually corresponds to 14 carat. In such a case, one should rely on the hallmark or calculate with the lower carat number as a precaution. In rare cases, the particular composition of the object causes an alloy with a high carat number to be on the border of the next lower carat range.
Counterfeits and low gold contents

| If the cursor flashes in the left, red range with the output “NO GOLD / 0 – max. 30% Au“, the gold content of the object is below the values typically used for gold jewellery. Low carat alloys are summarized in the range of 0-30% gold content. In the majority of these cases it is a material of low value, but also 6 or 7 K alloys are possible.

If an object with a 333 hallmark is on the left edge of the 8K range, you should be careful and polish a spot on the object with the glass fibre pen and measure again. Please also not the important information regarding jewellery without a (legible) hallmark.

| Beware of the following hallmarks “plated” / “double” / “americaner” / “alpaca/alpaca”: These are only galvanically applied gold layers on non- precious materials or so-called nickel silver.

Beware of so-called “Autobahngold”: These are low-value jewellery objects made of brass or stainless steel with or without thin gold plating, which are mainly offered at rest stops and gas stations. E.g. jewellery with hallmarks in the format “18K-0.750”, whereas the real hallmark is in the format “18K-750”.

Please inform yourself about country-specific hallmarks, seals of quality and minting on the Internet.

---|---
Platinum, Palladium or Rhodium- plated objects

| If the cursor flashes in the right, blue range, it is an object made of platinum or palladium or a rhodium-plated piece of jewellery. Please not the important information in the previous chapter. Caution: In some cases, V2A stainless steel is also in this range.

Please note that this value range applies to the respective pure forms and high-alloyed jewellery alloys. For instance, the frequently used palladium 500 lies in the range of 12-14 carat gold.

The measurement result of the CaratScreenPen is influenced not only by the gold content but also by other metals, especially silver and palladium. Thus, a high content of silver or palladium leads to a sometimes significantly higher result (output in the adjacent transition range or in the range of the next higher carat number) than the hallmarking of the object would suggest. This is because 14 K or 585 simply mean that the object has a gold content of 585 ‰. However, the composition of the other 415 ‰ depends on numerous factors. The desired color plays an important role: e.g. yellow gold, red gold, or white gold. The more reddish a piece of jewellery (rosé gold or red gold), the more copper is in the alloy. In white gold, on the other hand, the proportion of silver, nickel, palladium, or zinc is significantly increased.

Information for alloys with a gold content of 875‰ / 21 K or more
Please keep in mind that the CaratScreenPen should ideally only be used up to 21 K due to the measurement method used and the physical and chemical properties of the gold alloys. The target values for alloys from approx. 875 gold / 21 K move very close together, whereas you can differentiate well in the lower range. Therefore, the high carat range is also summarized as 21-24 K in the CaratScreenPen. For objects above 21 K, mostly small coins and bars, we recommend the additional use of another testing method: the determination of the electrical conductivity with our Goldanalytix GoldScreenPen. Further information on the GoldScreenPen and the electrical conductivity measurement method can be found online at
