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.

(A)

(D)

1) Loosen the screws (*1) securing the holder

(A).

Screws: CUK 3X6SA (*1) 2pcs.

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.
