Introduction

Congratulations on your purchase of the Goldanalytix MagneticScreenScale. The Goldanalytix MagneticScreenScale tests the authenticity of different precious metals fast and without destruction. The magnetic scales are suited for quick detecting of tungsten and  tungsten alloy (T/TA) inclusions in gold ingots or gold coins (minimum T or TA content of >40-50%).
Furthermore, magnetic scales are well suited for discovering tantalum falsifications of .900 or .916 gold coins. It is also possible to test the correct magnetic qualities of coins, jewellery and ingots of silver, platinum or palladium with the Goldanalytix MagneticScreenScale.
In general, you can differentiate between diamagnetic and para- or ferromagnetic metal species.
The result is revealed after a few seconds as difference in magnetic weight. A big advantage is the pervading method, i.e. the inner parts of the testing objects are examined (until a certain thickness), not only their surface. You can also test the objects within their plastic films or blisters. Thanks to the highly efficient accumulator battery, the magnetic scale allows you to test precious metal on-site and on the way.
Please read these operating instructions carefully prior to the first use in order to use the MagneticScreenScale properly. The MagneticScreenScale as the only method of measurement will not be sufficient for a definite result about the authenticity of precious metals. Please always test with one further method to surely exclude precious metal forgeries. Please note: The development of improved counterfeits is the goal of each forger. In order to stay up to date on this dynamic field we recommend you to inform yourself on our website at www.gold-analytix.com/magnetic-scale/under “downloads”. There you can find the most recent version of the instruction manual.

Measurement Principl

The measurement principle utilizes the different magnetic properties of precious metals like goldor silver in comparison to the frequently used metals of falsifications like tungsten, tantalum or molybdenum in a strong magnetic field. While gold and silver show diamagnetic properties (which leads to a weak repulsion of the magnet), tungsten, tantalum and molybdenum feature paramagnetic properties leading to weak attraction of the magnet.
This can be used in order to identify falsifications because of their paramagnetic properties leading to a negative sign on the scale. Due to the strong magnetic field of the measuring head the penetration depth is up to 2.5 mm (our experience with own test  eries).
Diamagnetism, paramagnetism and ferromagnetism assign different magnetic properties of the material. While diamagnetism and paramagnetism are not easily observable in the daily life, ferromagnetism is well-known.
In general, each material features diamagnetic properties, but these are overlapped by paramagnetic or ferromagnetic properties. Based on this, the separation can be done with regard to their magnetizability.
Ferromagnetic substances are strongly attracted by a magnet. At ambient temperatures metals like iron, nickel, and cobalt are ferromagnetic. Ferromagnetism is about 1000 times stronger than dia- and paramagnetism. GOLDANALYTIX HRA 9148 Magnetic Screen Scale -
FerromagneticIn contrast to that, paramagnetic substances are weakly attracted. Consequently, a strong magnetic field is necessary in order to gain a certain effect. Diamagnetic substances are weakly rejected by a magnet. Strongly diamagnetic materials e.g. are pyrolytic graphite and bismuth. They reject the magnet extraordinarily strong leading to high positive values on the scale. The difference in between dia- and paramagnetism is the basis of the authenticity test of precious metals with the help of the MagneticScreenScale. Pure silver and pure gold as well as their copper alloys cause a positive value due to the rejection of the measuring head. In case of a paramagnetic material, a negative value will appear because of attraction. Important to know: Ferromagnetic additives complicate the measurement with the  MagneticScreenScale because even tiny amounts can lead to misinterpretation of the result (seechapter 9: “Valuation of the measurement results”).

Handling of Strong Magnets

The MagneticScreenScale exhibits strong magnetic fields. Please be aware that no ferromagnetic / magnetic materials, electromagnets, magnetizable materials (hard disks, credit cards, mechanical watches, hearing aids) or other electronic devices are next to the measuring head of the scale.

Dangers

  • Strong magnets may cause bruises. Magnets can split by clashing them.
  • Mechanical work on magnets can lead to fire hazard.
  • Magnets are able to interfere with heart pacemakers and magnetic hard disks.
  • Magnets can be a health risk when in contact with food or drinking water.
  • Magnets are heavily hazardous to health when swallowed and can also lead to death. Security Instructions
  • Persons with a heart pacemaker should keep sufficient distance to magnets.
  • Magnets are not made for children’s hands.
  • Please keep magnetic hard disks and other electronic devices in a sufficient distance.
  • Do not bring magnets in contact with food.
  • Avoid mechanical work on magnets (e.g. drilling or sawing).
  •  Avoid loose magnetic items next to the magnet.
  • Do not bring magnets next to open fire.
  • Transport of magnets, especially by air freight, needs the fulfillment of certain regulations. These are also valid for included magnets. Please get informed about the valid regulations.

Assembly of the MagneticScreenScale

Step| Description|
---|---|---
1| Set the scale up on a plain and solid surface.
IMPORTANT: Please switch the scale on after finishing steps 2 & 3.|
2| Screw the measuring head carefully into the corresponding threads. Screw it not too firmly in order to avoid destruction of the measurement cell of the scale, but be aware that the measuring head is fixed tightly on the scales disk. The scales disk has to be beneath the measuring head!
IMPORTANT: The scale is set up in the manner, that 0.000 is shown after installing the measuring head.
Otherwise you will get the notice “— LH —” on the display.|
3| Place the Perspex hood on the scale like it is shown on the picture. The measuring head should not touch the hood after putting it on. The measurement principle is based on acertain, minimal distance in between the measuring head and the Perspex hood. In case of a contact, you may not have installed the easuring head properly as described in step 2.|

Preparing a Measurement
In order to avoid damage of the scales as well as inaccuracy during the measurement, we recommend taking the following steps into account:

  1. Commissioning and Choice of Location
    IMPORTANT: The scales only work after installing the measuring head. In case of not being screwed in you will get the error message “—LH—“.
    Please switch the scales on 5-10 min prior to the first measurement in order to guarantee highest precision. In that way the scales give you the best results because it needs assimilation of the temperature. Please be also aware of a calm location which is free from vibrations. The result of the scales is dramatically disturbed by vibrations, draft and temperature fluctuations. Please assure that no ferromagnetic tools or electronic devices are next to the scale (minimum distance >30 cm)! Do not put the testing object on the scales with the hand on which you wear your watch.

  2. Reference Measurements
    In order to assure proper measurement conditions, the suitcase also contains a graphite plate as reference. Put the plate on the target area prior to each measurement series (see chapter 8).
    The value should be in the range of +0.200 to +0.400 g. In case of differing significantly please be aware of the following hints.

  3. Temperature
    The ideal temperature for the measurement is in the range of 20 to 25 °C. It is also working in the range of 15 °C to 35 °C. Nevertheless, you should avoid very high or low temperatures, because of the magnetic force being temperature dependent. Please also ensure that the temperature stays constant during the measurement! Upon heating the magnet above 80 °C, it will lose the magnetization permanently!

  4. Testing object
    The testing object has to be dry and clean, but can be wrapped in standard blisters,  oils and capsules. Please be aware, that the plastic of capsules etc. also has diamagnetic properties (leading to a slightly positive value on the scale). Consequently, capsules which are too thick might falsify the result. By using common packaging disturbing  eviations ought not to be a problem.
    Nevertheless, our recommendation is to measure the objects without packaging.

  5. Pre-Test with rod magnet
    Please ensure that no ferromagnetic material (iron, nickel or cobalt) is next to the strong magnet. That´s why you should check the testing object whether it contains ferromagnetic additives like iron, nickel or cobalt with the small mini magnet. In case of not applying this hint, the measuring head might be damaged or you even get hurt! (see chapter 5: Handling of strong magnets)

  6. Electrostatic charge of the plastic parts Please avoid electrostatic charge of the Perspex hood or capsules while dealing with the MagneticScreenScale. Due to polymers are able to get electrostatically charged leading to an interaction with the magnetic field, the prevention of the charge is highly recommended.
    Please keep in mind that rubber gloves or similar materials might lead to electrostatic charge of  the Perspex hood or the capsules. However, when any part got charged please use the antistaticspray in order to get rid of the charging. It is a good practice to cover the surface with the spray and wipe it off with a paper tissue prior to each measurement. Please have a look on the safety hints on the spray tin. In case of doubt please check if the graphite plate is in the range of +0.200 g to +0.400 g.

Performing a Measurement

Step| Description|
---|---|---
1| After installing the scales:
Switch them on and wait until 0.000 is displayed. Please ensure that themeasuring head has already been screwed in (see chapter 6). Now you can check if the graphite plate is in the range of 0.200 g to 0.400 g (see p. 7, point 2).|
2| After removing the reference plate,push the “TARE” button “–>0<–” sothat 0.000 is shown. Now you canplace your testing object (here: a goldbar) on the target area (in the middleof the Perspex hood). After reaching a stable measured value you can fix theresult. Usually, removal of  listers,capsules or foils is not necessary (seep. 8, point 6).|
3| If the display shows a negative value for gold, it might be a falsification with high chance. Typical falsifications contain a tungsten core (see the following chapter „Valuation of the
measurement results“).|
4| Remove the object from the scale and push “–>0<–” for taring, that 0.000 is displayed. Now you can continue with the next object.|

Valuation of the Measurement Results

Please consider the following measures and hints in order to avoid misinterpretation of the result:

  1. Measurable Thickness
    Please be aware that paramagnetism, for example, is more pronounced than the diamagnetism of gold. In this regard, a tungsten core can be identified beneath a gold layer with a thickness of 2.5 mm (however, the mass of tungsten has to be 40-50% of the total mass). Therefore, the MagneticScreenScale is a secure and reliable detector for paramagnetic inclusions in gold or silver for common bars and coins up to 250 g.
    An exemplified consideration should illustrate that: Typical dimensions of a 100 g bar are 50 mm × 29 mm × 4 mm. This means that a forger has to include only a very thin layer of tungsten in order to not be detected. This might not be profitable for a forger.
    Above 250 g, the situation is different. In this case, bars often feature a thickness of up to 9 mm.
    If you consider that the penetration depth ideally is about 2.5 mm (from each side; together 5 mm), a forger still could include 4 mm of cheap tungsten.
    This does not mean that a gold cover of such thickness is common. Mainly, the identified falsifications of e.g. 250 g bars exhibited a gold layer of less than 1 mm which would have been easily identified by the Goldanalytix MagneticScreenScale. Nevertheless, we ask you to please follow the aforementioned instructions regarding the dimensions by selecting the testing objects.

  2. Pure Materials
    The measured values of pure materials behave as shown in the following table: Diamagnet| Paramagnet| Ferromagnet
    ---|---|---
    Positive Sign (+) at Measurement| Negative Sign (-) at Measurement| Highly negative Sign (-) at Measurement
    Bismuth
    Beryllium
    Carbon
    Tellurium
    Tin
    Zinc
    Silver
    Gold
    Lead
    Copper| Molybdenum
    Tungsten
    Magnesium
    Aluminum
    Tantalum
    Platinum
    Rhodium
    Titanium
    Palladium
    Manganese| Iron
    Nickel
    Cobalt

That means that, for example, a silver or gold coin usually gives a positive value. Other materials like pure copper or lead show a similar behavior. Bismuth is the metal featuring the highest diamagnetic behavior and consequently gives the highest positive value with respect to an identical geometry.
This might lead to a situation in which a falsification with a bismuth coverage containing a paramagnetic core does not lead to a negative value on the MagneticScreenScale. However, those falsifications are expensive to produce and the relatively low  ensity of bismuth would lead to strong deviations of the dimensions and the mass compared to gold or platinum.

  1. Paramagnetic Cores
    In case of the presence of ferromagnetic impurities within the paramagnetic core (e.g. a tungsten copper alloy with trace amounts of iron) inside silver- or gold objects, the scale will display significantly negative values of -1 g to -6 g.
    Please keep in mind that forgers usually do not use tungsten alloys with iron or nickel impurities so that the values on the scale might be much lower.
    The following example should illustrate that:
    A measurement series with brass plates and a highly pure tungsten copper piece should illustrate the reach of the magnetic measurements.
    We placed a 30 mm × 5 mm, 99.95 % pure tungsten copper plate (80/20 alloy), which is a paramagnetic material often used for fakes of Krugerrand or American Eagle coins, on the MagneticScreenScale. The measured value was -0.063 g.
    Afterwards, a diamagnetic brass disk with a thickness of approx. 0.4 mm and a diameter of 10 cm was placed beneath the tungsten copper piece. This imitated the inclusion of tungsten copper in gold or gold alloys. Up to 5 of those brass disks (total thickness of 2.0 mm) a negative value was identified on the display. The sixth disk (total thickness of 2.4 mm) lead to a slightly positive value (0.010 g).
    However, this was also an indicator for a falsification because the brass amount (comparable to .916 gold alloys) without tungsten copper should give a value of +0.040 g. In case of even thicker layers the values will become more positive which in turn would no more be identifying because the distance of the tungsten core to the magnet also increases.

  2. Ferromagnetic Impurities
    Some of the alloyed gold coins (especially the ones minted before 1945) like Vreneli, Latin Monetary Union, Austrian Kroner (.900 alloy), American Eagle (some older years), Krugerrand, UK Gold Britannia (years before 2012, .916 alloys), other alloyed and especially older gold coins can contain (but do not need to!) tiny amounts of ferromagnetic substances like nickel, iron or cobalt. This may lead to that those coins or basically objects made from those materials give a negative value on the Magnetic ScreenScale contrary to the expectations. The reason is that (as already described above) ferromagnetic material is strongly attracted by a magnet. That means that even traces of these elements can lead to negative values. Please be aware of this hint
    when interpreting the result.
    IMPORTANT NOTE : Additives of nickel are possible for pure gold and pure silver coins, however, it´s quite unusual for common coins. It is therefore necessary to pay attention if negative values are displayed. In case of values below -0.050 g, something must be wrong and has to be double checked. An exceptional case is the Australian Koala silver coin. It seems to contain tiny amounts of ferromagnetic materials. Hence, the 1 oz Australian Koala silver coin was the only coin we observed during our investigations giving a negative value on the scale (despite it is genuine).
    The fineness of most of the silver coins is “only” 999.0 per mille instead of 999.9 per mille so that the remaining ten thousandth might contain ferromagnetic material. Please keep this in mind during the measurement.

  3. Ferromagnetic Materials
    In case of being made from ferromagnetic material, containing ferromagnetic alloys components or higher portions of ferromagnetic material you should expect strongly negative values up to the limit of the scale (in that case the value is no more  isplayed). Please test your object prior to the measurement with the help of the provided small rod magnet, if it contains ferromagnetic material leading to attraction of the magnet. Don´t place such objects on the Perspex cover, as you might get hurt. Besides, the pre-test avoids that the measuring head is lifted out of the cone of the scale, which in turn leads to damage of the scale.

  4. Further precious metals and combinations of materials
    In addition to gold, silver, platinum and palladium, you can also test for foreign metal inclusions with the MagneticScreenScale. Please consider that the fake material has to feature magnetic properties contrary to the corresponding precious metals in  rder to be identified by the magnetic scale.
    For example, gold and silver are weak diamagnets (in comparison to metals like bismuth, beryllium or antimony). However, viewed relatively, palladium as well as platinum is a strong paramagnet. That means that a bismuth core within palladium could be detected, whereas a titanium core could not. The reason is that titanium also exhibits strong paramagnetic properties (see the following table and figure). The dimensions of the corresponding coin or bar would of course differ significantly, because the density of titanium is much lower than palladium (4.50 3 3 g/cm vs. 11.99 g/cm ). Hence, the test of the weight and the dimensions are inevitable during the testing process.
    The following table and figure give an overview of the magnetic properties and the corresponding specification (given as „magnetic susceptibility“ of the mass). Having this overview in hand, you are able to judge which kind of falsifications can be identified in a realistic manner. Please take the susceptibility as a proportional factor for the amplitude to the corresponding direction (negative or positive) on the MagneticScreenScale.
    Please do not get confused with the signs – a paramagnet gives a negative value on the scale (attraction) whereas a diamagnet gives a positive one (rejection). For example, a random piece of bismuth will show a higher positive value than a piece of copper with identical geometry.

  5. Selected dia- and paramagnetic metals
    The following table and figure give an overview of different magnetic properties of metals and their strength. The so called magnetic susceptibility is given in 10 -9 3 m/kg: Diamagnets| Magn. susceptibility| Paramagnets| Magn. susceptibility

GOLDANALYTIX HRA 9148 Magnetic Screen Scale - Selected

Features of the MagneticScreenScale

  1.   Commissioning and Operation
    After installing the scale, it should be leveled (i.e. placed plane to the ground). In order to be leveled, the scale features adjustable feet and a water level. Please screw the feet as long as the air bubble in the water level is adjusted in the center.
    • Switch the scale on with the ON/OFF button.
    • The scale will perform a selftest after pushing the ON/OFF button.
    • After finishing the test „0.000“ appears on the display.

  2. Warm-up period
    The temperature should be in the range of +15 °C to +30 °C to perform properly. In the period of temperature stabilization, the shown values can change. Hence, the adjustment should be done after that warm-up period.

  3. Keyboard GOLDANALYTIX HRA 9148 Magnetic Screen Scale - KeyboardIn order to zero the display, please press the “-> 0 <-” button. The zero appears at the display.
    The scaling to zero is only possible when the MagneticScreenScale are placed properly on the ground. Hint: The zeroing is only possible in the range of ± 2% of the maximum load. If the value is above ± 2% of the maximum load, “” appears and an acoustic signal is given.

  4. Charge and Discharge of the battery
    When the level of the battery is low, the battery symbol will appear on the display. That means that the battery immediately should be charged. The battery can be charged with the provided charger (network operation is also possible). The charge status of the battery can be displayed with the key combination ESC+T.

  5. Error Messages
    Error message| Description
    ---|---

  6. Time, date and more functions
    The combination ESC + 0 lets the scale display the time. By pressing 0 it changes to the date.
    When you want to set the time or other values, the setup must be opened (ESC + arrow key). To switch between the submenus, press >0<. To go down one menu level press >T<, to go up ESC. To change the value in a menu, press the >0< button. With >T< you jump to the next digit, with the arrow the value is confirmed.
    Here is a list of the menu items in which you can change the respective setting:
    Date: 7.5.dAT,
    Time: 7.6.5.tnn
    Beeping sound: P7.2.bEEP

Comparative Values

The following table gives an overview of values which we recorded with the Goldanalytix MagneticScreenScale. Please consider these values as an indicator for the target range. The measured values of your measurements can deviate in certain ranges depending on the year and batch of the corresponding coin or bar. The setup of the scale also plays an important role (especially the distance of the magnet to the Perspex hood). In case of showing a significantly different value you should have a closer look on the testing object. Bars >250 g are consciously not listed below because counterfeits with tungsten rods or tins being covered with a thick layer of gold are not unequivocally identified. Bigger bars can be naturally checked with the MagneticScreenScale up to a penetration depth of ca. 1.5 mm. Nevertheless, in order to explicitly verify the authenticity of the testing object you need to utilize another testing method, i.e. ultrasonic testing. All information is without guarantee.

The magnet is so strong that even slight inattention can lead to body parts (like fingers) being clamped in between the magnet and another object. This may lead to bruising for several weeks.
Danger for heart pacemakers
Do not let the magnet get close to people with heart pace- makers. This may cause potentially life threatening damage. Please warn patients from getting to close to the mag- net
Risk of ignition
If the magnet gets damaged the produced dust may become inflamed.
Danger for Kids, allergy sufferers and with collisions
Do not let the magnet get into the hands of kids!
The magnets are coated with nickel. Some people are allergic to nickel.
Please avoid long skin contact with the magnet if the protection sticker got removed or damaged.
If the magnet collides with a object splitters may develop, which could fly several meters and might injure eyes or other body parts.
