Trim the sample with a trim 45 or a trim 20 diamond blade. The sample width should be a maximum of 0.5 mm.
With the use of an eyepiece graticule in one of the stereomicroscope oculars (graticule 10450336 for the Leica M80). Sample block (fixed in the sample holder), is mounted in the trimming plate. Measure the height with the graticule.
When working in resonance, the sections may drift slightly to the right or to the left. If this is the case, the following procedure helps: Switching from AUTO to MAN. Now increase or decrease the the frequency a few hundred Hertz, until the sections float straight on the water surface.
If sections drift to the right: decrease the frequency. If sections drift to the left: increase the frequency.
