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.

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.
