•
Press the stage to the front against the spring pin and lower towards the back of stage carrier
(2-35/
3 ), then release it.
•
Tighten screw cap (2-35/ 2 ).
c) Centering the stage
When objectives with high magnification are used,
centering can be exact for one selected objective
only.
All stages are factory-precentered, i.e. a set
specimen detail remains in the image center when
the stage is rotated. If the image detail moves
from the image center (2-36/
5 ) with the stage
rotating, recentering should be performed as
follows:
•
Undo stage clamping screw (2-36/ 4 ) and the
screw cap on the stage carrier (2-36/ 1 ).
•
Rotate the stage to determine the maximum
specimen deflection (2-36/5, tip of the arrow)
in the direction of the eyepiece reticule.
•
Reset the two centering screws on the stage
carrier (2-36/
2 ) using one SW 1.5 Allen
screwdriver (2-36/ 3 ) each to move the
specimen detail by half the arrow length in the
direction of the crossline center. Check whether
the specimen detail moves when the stage is
rotated again; repeat the procedure, when
required.
•
When centering is finished, tighten screw cap
(2-36/
1 ) again.
The stage can be turned through 240° up to a
range of y
≤
27 mm. No rotation is possible above
this range of movement.
