2. Mechanical adjustment
2-1 Adjustment metod for the tension of X/Y-wire
If a specimen image is moved when the stage is brought into the desired position of
specimen, it is necessary to adjust the wire tension of stage.
( In case where the stage movement is heavy due to hardening of grease, please contact
your Authorized Olympus dealer because disassembling the stage is required for
grease replacement.)
Adjustment method for X/Y-wire
(Refer to the figure shown below.)
1) Remove the stage from the frame.
2) Turn over the stage and loosen the two fixing screws (CUKSK3X6SA) securing the
holder.
3) Turn the adjustment screw (CSK3X5SA) clockwise or counterclockwise to adjust
the wire tension (See page 15). Tighten the two fixing screws (CUKSK3X6SA).
4) Mount the stage to the frame, set the microscope at observation state and check
that the image is brought into the desired position without backlash (within 2
microns at the lowest torque of X/Y stage knob: see page 16).
5) Repeat the procedure 1) to 4) until the condition is satisfied (both X and Y wires).
6) After completing the adjustment , apply adhesive (OT1131) to each three screws.
