Leica Comprehensive Guide for Operating and Focusing Your DM1000 Microscope

8. Operation

Right-/Left-hand Operation

The coaxial pinion can be attached to either side of the stage (also see 6. Assembly, p. 16 onwards). To change the side, follow these steps:

•Loosen the lock screw (37.5) at the bottom left-hand side of the stage; the necessary tool is attached to the bottom of the stage on the right-hand side

!Caution:

8.3 Focusing

Coarse and Fine Focusing

Coarse and fine focusing wheels are located on either side of the stand (fig. 37 and 39).

The special form of the flat fine focus wheel (37.3) lets users enclose the coaxial pinion in their hands while operating the fine focus with one finger. The flat wheel should therefore be mounted onto the appropriate side.

See right-/left-hand operation of the stage.

Height Adjustment of the Focusing Wheels

The condenser must be lowered!

•Slide the stage all the way back

•Release the screw (37.6) on the coaxial pinion and pull the pinion out

•Place the flat fine focus wheel (37.3) on the side to which you intend to mount the coaxial pinion; the wheel is held in place magnetically; ensure that the button snaps into place. Attach the other focus knob on the opposite side

•Defocus the image by moving the stage down with a full turn of the coarse focus wheel (37.2, 39.1)

•Grasp the right-hand and left-hand focus knobs at the same time and press the knobs gently upward or downward into the desired position

•Refocus the image

•Fasten the coaxial pinion to the other side of the stage by retightening the appropriate screw.

•Return the stage to the starting position and retighten the lock screw; after installation of the stage control, move object guide all the way to the left side of the instrument; keep turning when guide has reached the end of travel until a click noise is heard
