Confirmation of X/Y-wire tension in observation state :
1) After checking the above condition, Install the mechanical stage to the plane stage in reverse

order of disassembly 1) on page 14, set the microscope at observation state and check that
image is brought into the desired position without backlash (2 microns: with100 X objective).
2) If it is out of standard, repeat the above procedures until the condition is satisfied.
3) In case where the image backlash can not be eliminated, perform the knob tension adjustment
referring to 2-4 on page 16.
(A)
(D)
*Check that Y-knob (C) is
rotated following the
movement of Y-body-1(D)
when moving the Y-body-1
in stroke by a hand.
*Push the wire (B) to the
wall (b) to check the tension
in the same manner as
X-wire.

(D)
1) Loosen the screws (*1) securing the holder
(A).
Screws: CUK 3X6SA (*1) 2pcs.
*1
2) Adjust the tension of the X-wire (B) by
moving the holder (A) in arrow directions as
shown in the left figure.
3) Temporarily tighten the screws (*1).
4) Check the tension of X-wire if it is too tight or
loose while pushing the X-wire (B) to the
wall (a) in arrow direction. <Fig.1>
If the tension of wire is loose, slip may occur
between the X-knob and X-wire.
Therefore, check that X-knob (C) is rotated
following the movement of guide (D) when
moving the guide in stroke by a hand.
If the tension is too tight and the X-wire does
not come in contact with wall (a) due to no
deflection, it may cause image backlash.
Therefore, confirm it in observation state as
described below.
1) Loosen the screws (*1) securing the holder
(A)
Screws: CUK 3X6SA (*1) 2pcs.
2) Adjust the tension of the Y-wire (B) by
moving the holder (A) in arrow directions as
shown in the left figure.
3) Temporarily tighten the screws (*1).
4) Check the tension of Y-wire if it is too tight or
loose while pushing the Y-wire (B) to the
wall (b) in arrow direction.
