7. Insert the sample holder flange into the chamber
as described in
7.1.2 Matching Sample Holder Height to
Sample Thickness
The sample holder can be manually aligned by
± 2.5 mm with the alignment equipment of the
HTK 1200N or automatically by ± 3.5 mm using the
motor-driven alignment stage.
For samples thicker than 2.5 mm (3.5 mm), the
sample holder height can be varied by demounting
the spacer ring (1). The 4 mm spacer ring is includ-
ed in the delivery and is already mounted.
TIP: Before removing the spacer ring make sure
that the HTK 1200N is aligned properly! If not, re-
align by means of the alignment slit (refer to chapter
5 for further information).
To remove the spacer ring (1), demount the sample
holder first (see
and
).
Then remove the O-ring (2) and afterwards the
spacer ring. Mount the O-ring and then the sample
holder again.
When mounting the spacer ring again, demount the
O-ring first and make sure that the centering pins of
the spacer ring rest in the corresponding grooves.
Then mount the O-ring again and then the sample
holder.
CAUTION
Hot surface
Make sure that the sample holder is at room
temperature before touching it. We recommend
using a suitable meter for checking the tempera-
ture of the sample holder surface.
