IMPORTANT: The specimen base that comes with the system is round. When loading an
angular specimen, select an appropriate specimen base so that the entire
specimen will fit on the base. Movable range limits are established by restricting
the operating range for the X and Y-axes to within the diameter of the specimen
stand and by calculating the safe operating range for the Z and Tilt axes.
For example, if a square specimen measuring 50 mm on the edge is affixed onto
a 50mm-diameter specimen base and the specimen is rotated 45°, the size of
the specimen in X and Y directions will be 70 mm, which means that the
specimen cannot be protected safely if its size is set to 50 mm. In such a
situation, either use a 77-mm (3-inch) specimen base or specify a specimen
setting (see 3.5.6.6) of 77 mm (3 inches) rather than 50 mm (2 inches).

3.2.3.1 Setting the Specimen Stand
Combine the adjustable screw, locking ring, and holder base, and screw the stub to the
adjustable screw. Tighten the locking ring so that the adjustable screw will not become loose.
Fig. 3.2-1 Fixing the Specimen Stub
3.2.3.2 Measuring and Setting the Specimen Height
Loosen the locking ring for the specimen stub. Use an adjustment screw to align the highest
position of the specimen to the Standard (45 mm) mark on the height gauge, and fix the
specimen using the locking ring so that the adjustment screw will not become loose. The height
of the specimen base from the bottom to the specimen surface is 45 mm. See Section 3.5.7.3 for
further details.
