USING THE MICROSCOPE
ARTICULATED ARM
The articulated arm includes a number of features that enable the microscope to be adjusted in
almost any position.
1.
The horizontal arm may rotate about the vertical pillar by unlocking the pillar lock knob. To
prevent the arm from rotating, simply lock the knob.
2.
The pantograph (moving) arm may rotate about the end of the horizontal arm by unlocking
the elbow lock knob. To prevent the arm from rotating, simply lock the knob.
3.
The amount of force required to move the pantograph arm up and down may be adjusted by
rotating the screw located at the top of the elbow joint. To adjust the gas spring force, first
move the pantograph arm down to reveal the screw through the slot in the top of the arm.
Use the socket key located in the toolbox to rotate the screw. To decrease the amount of
force required to move the arm, rotate the screw clockwise. To increase the amount of
force required to move the arm, rotate the screw anticlockwise. If the screw is adjusted to
its limit, rotate the screw half a turn in the opposite direction to ensure the arm continues to
operate smoothly.
4.
The amount of friction in the pantograph arm may be adjusted by rotating the handle located
on the side of the pantograph arm. The arm may be locked in any position or alternatively,
the amount of friction can be set so that the arm is stable but will move when a force is
applied.
5.
The wrist lock knob located on the under-side of the end of the pantograph arm is used to
lock the microscope assembly into place. To release the microscope assembly, simply
unscrew the knob and lift the assembly carefully out of the collet.
6.
The microscope head may be tilted up by some 5
â
and down by 45
â
by rotating the tilt
adjustment knob. To tilt the head down, rotate the knob in the clockwise direction. To tilt
the head up, rotate the knob anticlockwise.
7.
The guide handle may be used to manoeuvre the microscope once the appropriate friction
has been set on the other knobs.
