3. Put the sample on the transducer. Slightly pressing the sample with tweezers make
several short movements along the transducer surface to ensure optimal spread of the
honey and better contact between the surfaces.
After completing the manipulations described above it is strongly recommended to wait for
some time (about one hour) before starting the measurements. This would allow the sample
to glue better to the transducer surface and would also minimize vertical drift of the sample
that can make the measurements difficult or even impossible.

1.3. Choosing the Probe
When choosing the probe it is recommended:
−
to use “rigid” probes (k~30 N/m) for measurements on rigid surfaces (semiconductors,
metals, etc.);
−
to use “soft” probes (k~1
Н
/
м
) for soft surfaces such as polymers.
