THE TEST PROBES
ial and must be in measuring mode.) The Vickers diamond may touch the
surface slightly, but not for too long (otherwise an error occurs). Then the
probe is pressed to the specimen until the protective sleeve hits the sur-
face. An acoustic signal indicates the completion of the measurement. To
achieve an accurate measurement, the probe must be pressed steadily
and vertically onto the specimen.
To facilitate the measurement procedure, probe supports can be at-
tached to the probe in place of the protective sleeve. These probe sup-
ports are obtainable for flat and convex surfaces.
A high precision stand is available, which eases load application, particu-
larly when a large number of measurements has to be taken or in case of
a high test load.
