If the measured value of is below or above the tolerance range, it is recommend to
perform a second measurement at another position of the gold piece. At a bar, this
second measurement could be taken at different sides.
If then there are still differences, which are out of the tolerance range, there is a
suspicious fact, that there might by a false core.
11 Alternative measurement procedures
The most traditional procedure to check the genuineness of gold pieces is the deter-
mination of density in a liquid.

12 Instruction Manual of TD-US as a base for using TD GOLD 40
12.1 Features
* The exclusive Micro- computer LSI offers high measurement accuracy.
* The instrument offers high power of emission and a wide spectrum of receiving
sensitivity.
* Sensors of different frequencies can be identified.
* Rough surfaces, even cast iron, can be measured.
* It is used in almost all kinds of industries.
* Convenient to measure the thickness of many materials, e.g. steel, cast iron, alu-
minium, red copper, brass, zinc, quartz glass, Polyethylene, PVC, grey cast iron,
nodular cast iron.
* Automatic power-off to preserve batteries.
* Data transfer to PC possible. Cable and software can be obtained as optional ac-
cessory.
Annotation: It is strongly recommended to calibrate the new instrument before
the first use, as described in paragraph 5. By doing this it will be achieved a
much better measurement result right from the start.
