Info
Please bear in mind that the device at hand is a
precision measuring device that can determine coating
thicknesses of no more than a few micrometres (1µm
is equivalent to one thousandth of a millimetre).
The surface condition of most measuring objects is
hardly ever perfectly even and homogeneous, even
though it might appear differently to the naked eye.
Observed under the microscope, even the smoothest
surface looks much like a mountain and valley
landscape. The teensiest of scratches, cavities or
contaminations can therefore already have a negative
effect on the expected measurement result, seeing as
they will also be a part of the measurement to a
greater or lesser extent. It does, however, not affect
the accuracy of the device. Even after the calibration
unexpected measurement deviations of a few
micrometres always have to be regarded in this
context.
Hence it is important to handle the supplied calibration
accessories with care to avoid scratches and dirt on
their respective surface as far as possible.
