Fix the specimen slide on the
mechanical stage using the
slide-clamp. Ensure that the
specimen is centred over the
stage opening. (Fig.20)
If you have a very high sam -
ple that doesn’t fit under the
objectives, the B-1000MET
stage can be further lowered.
(Fig. 21)
Loosen the fixing screw and
lower the stage.
Turn the tension-adjust knob
to get a suitable tension for
the focus system. (Fig.22)
NOTE : if the tension is too lo -
ose, the stage could go lower
by itself or the focus easily
lost after fine adjustment. In
this case, rotate the knob in
order to increase the friction.
Loosen the focus-stop knob,
rotate the coarse focusing
knob to bring the slide into
focus with a 5X or 10X objecti -
ve. Then rotate the focus-stop
in order to block the height of
the stage. This simplifies the
next focusing operations.
The focus-stop knob is also
useful to avoid accidental con -
tacts between objective and
specimen. (Fig.23)
