SAFETY PRECAUTIONS

Fig. 3

1. Keep your hands apart from the revolving nosepiece during focusing
operation and while the main switch of the BX-UCB control box is set to
“ I ” (ON). If your finger is caught by the up/down movement of the revolving
nosepiece, an injury such as bone fracture my result.
Should your finger be caught by the revolving nosepiece, lower it with the
following method:

· Set the main switch to “ ” (OFF), remove the right side panel of the
illuminator using a Phillips screwdriver and turn the manual knob 1 inside
the panel in the opposite direction to the direction shown in the figure (i.e.
clockwise) to lower the revolving nosepiece. (Fig. 3)

2. Emergency stop of focus operation is possible by turning the focus
adjustment knob on the microscope frame or on the U-FH (in either
direction), or by pressing the FOCUS control button ( , , F/C or ESC),
after focus operation has been activated (except when data is being
downloaded to a PC).
When the BX-UCB control box’s main switch is set to “ I ” (ON), the focus
operates automatically (the objective raises once and then returns to the
original position) for initialization. (It takes about 20 seconds.)
If the above emergency procedure is performed during this automatic
focus operation, the microscope stops operating. Should this happen,
set the main switch to “ ” (OFF) and then “ I ” (ON) again.

3. The surface of the lamp housing on the side of the illuminator becomes
very hot. When installing the system, leave spaces of more than 10 cm
around, particularly above the lamp housing.

4. Be careful not to touch the lamp housing when centering the aperture
iris diaphragm or controlling the field iris diaphragm. You run the risk of
burn if you touch the lamp housing while the lamp is lit or immediately
after it is turned off.

5. Route the connection cables away from the lamp housing. Should a
cable comes in contact with the hot lamp housing, the cable could melt
and cause electric shock.

6. When installing the illuminator in an existing system, insert 6 bolts in the
module installation screw holes and tighten firmly.

-- Adjust the lower hardware limit using the following procedure. --

?The lower hardware limit of the objective has been set to the lower limit

of the stroke before the system left the factory.

!During adjustment, do not approach your hand to the motor drive

mechanism so that your finger does not be caught by it.

#The lower hardware limit determines the lower limit of the objec-

tive to prevent it from collide with the specimen. As a result, note
that there is a risk of collision with specimen or reaching the lower
limit before the focusing position when the specimen is not flat, the
specimen thickness is changed or the WD (Working Distance) of
the objective in use is 1 mm or less.

#Always use the procedure described below. Otherwise, it will not

be possible to avoid collision of the objective with the specimen
perfectly.

#During adjustment, do not touch any electronic part to avoid its static

destruction.

#During adjustment, do not touch the motor mechanism or electronic

part to avoid their malfunction.

1. Set the main switch of the control box to “ I ” (ON).

2. Remove the side panel of the illuminator by removing the screws using a
Phillips screwdriver.

3. Among the objectives mounted on the revolving nosepiece, engage the
one with the shortest WD in the light path.

4 Using Eyepiece Micrometer Disks

Eyepiece micrometer disks can be inserted into the WHN10X-H (or
WHN10X) eyepieces.
However, if the eyepiece does not have the helicoid adjustment facility
and your eyesight is poor, you may have difficulties in focusing on the
eyepiece micrometer disk. In this case, it is recommended to look into
the eyepiece through your eyeglasses.
Use 24 mm dia. x 1.5 mm thick micrometer disks.
Following Fig. 15, unscrew the micrometer mounting frame 2 from the
eyepiece and place a micrometer disk 1 into the mounting frame. Reat­tach the micrometer mounting frame in the original position.

6 Adjusting the Tilt

}Adjust the height and tilt of the observation tube to obtain the most com-

fortable viewing position.
Holding the binocular section with both hands, raise or lower it to the
desired position.

# Never attempt to force the binocular section past the upper or lower

stop position. Applying excessive force could destroy the limiting
mechanism.

# The U-TBI3 cannot be used in combination with any intermediate

attachment.

4-4 Differences in Operating Procedures of Software BX2-BSW

}The BX2-BSW software has been designed for controlling the motorized operations of the BX61 microscope system.

When the illuminator is controlled from the BX2-BSW, some operations may differ from the information shown in the
operation screens, tutorial and help of the software as described below.

1-2 Setting Procedure

1-2-2 Initial setting

2. Motorized unit setting (Device Type)

· Frame Enter “BX61F” or “BX61WI”. (Any can be entered without problem.)

· Reflected light illumination BX-RLAA

· Filter wheel U-FWR (The U-FWT cannot be used.)

· Autofocusing unit U-AFA1M

· Focus adjustment knob unit U-FH

(Note)

Text “enabled when the focus adjustment knob unit is installed” should be deleted.

3. Observation method setting (Microscopy Tab)

· Check only “EPI BF” (reflected light brightfield observation) and “EPI DF” (reflected light darkfield observation).

4. Mirror unit setting (Mirror Unit Tab)

· Enter “BF” or “DF”.

6. Turret optical device and top lens setting (Condenser Tab)

· Do not register anything.

7. Filter setting (Filter Tab)

· The U-FWT cannot be used.

1-2-4 Button function allocation

1. Button selection

Main Unit Tab

· Allocation to all of buttons 1 to 8 is possible with the PC screen operation.

· Even when button functions are allocated on the main unit, standalone operation on the main unit is impossible
(because the buttons are not present).

Other caution

· The microscope illustrations in the operation screens show the BX61.

Glossary of Terms Used in the Optical Characteristics Table

Working distance (WD) : The distance from the top of specimen and the front lens of objective.
Number of aperture (NA) : Important figure determining the objective characteristics (resolution, focal depth and bright-

ness).

Resolution ............. Increases in proportion with the NA.

Focal depth ......... Decreases in proportion with the NA.

Brightness ............. Proportional with the square of NA (comparison under the same magnification).

Resolution : The limit that an objective can identify the images of two points that are close to each other,

expressed as the distance between the two points on the specimen.

Depth of focus : The maximum depth of the specimen at which the entire specimen can be brought into focus

simultaneously. This value increases when the aperture iris diaphragm is narrowed and de-

creases when the objective NA is increased.
Field number : The diameter of the image area that can be observed through the eyepieces, expressed in mm.
Field of view : The diameter of the area observable on the specimen, expressed in mm.

Installation by the Left Side Panel

The illuminator can be installed by the 6 screw holes 1 on the left side
panel.

· Attach the illuminator firmly by the 6 bolts (with threaded section length
of no more than 10 mm).
If the number of bolts is insufficient, the illuminator installation may be­come unstable.

· The installation surface on the illuminator left side panel has two posi­tioning dents 2.
To obtain the standard position, clamp the illuminator by pushing it up
and rightwards by using the dents.

Installation by the Bottom Side Panel

The illuminator can also be installed by the 6 screw holes 3 on the
bottom panel.

· Attach the illuminator firmly by the 6 bolts (with threaded section length
of no more than 10 mm).
If the number of bolts is insufficient, the illuminator installation may be­come unstable.

· The installation surface on the illuminator bottom panel has a positioning
section 4.
To obtain the standard position, clamp the illuminator by pushing it up
and rightwards by using the positioning section.

· Stop the 6 screw holes 1 (Fig. 18) on the left side panel with the pro­vided seals to prevent leakage of light and penetration of dust.

2 Installing the Z-Board or AF Control Board

}For use in focusing control, either the Z-board or AF control board can be installed in the BX-UCB control box.

Do not install both of these boards for this will lead to malfunction.
When installing the Z-board, be sure to use the U-ZPCB(T2) that is compatible with the BXFMA-F.

# The Z-board or AF control board is a precision electronic component that could be damaged critically by static

electricity. Since the human body is usually charged with a small amount of static, be sure to discharge your body
before proceeding to the installation. The static charge in the human body can be discharged by simply touching
any metallic object with a finger.

Installation of the Z-Board or AF Control Board (Figs. 20 & 21)

}The on-board DIP switches on the Z-board or AF control board have

been set at the factory for use with the BX61 microscope. (All of switch
segments in SW1, 2 and 3 are set to OFF.)
Change the setting of the DIP switches for use with the BXFMA system.
