12. Do not operate the clutch lever of the stage while it is moving (page
36). Otherwise, accuracy deterioration or damage may result.
13. To maintain accuracy, it is recommended that the microscope
undergoes the Olympus periodic inspection service (accuracy
inspection, calibration, functional check, etc.) once a year. It is
recommended that the microscope also undergoes this service
when the microscope has been reinstalled at a different location.
(Note that this service is subject to charge.)
14. In case of emergency, unplug the power cord to stop supplying
electricity.
Install the microscope at a location where you can reach the power
cord connector (rear of the control box) or the outlet at hand to
disconnect the power cord.
15. The basic software (STM7-BSW) can also be used with the
measuring microscope STM6 (with some restrictions).
16. The hardware of STM6 is not compatible with the hardware of STM7.
If modules other than modules described in this instruction manual are

Emergency stop switch
1. The emergency stop switch bon the control box for motorized
STM7-CBA forces the Z-axis movement to stop. (motorized frame
only)
In case of emergency, press the emergency stop switch.
2. To release the switch, rotate the emergency stop switch in the
resetting direction (clockwise), and then rotate the fine/coarse
focusing knob of the focus controller STM7-MCZ to move the
focusing unit to the safe position.
Then, set the main switch of the control box for motorized to " "
(OFF), and set the main switch of the control box for motorized to "
" (ON) again.
When the main switch is set to " " (ON), five short beeps indicating
an error are generated. (When using the digital indicator STM7-DI,
the display shows “013F1507”. To cancel this error, operate either the
FOCUS buttons or the fine/coarse focusing knob of the focus
controller to move the Z-axis by 50 μm or more and set the main
switch to " " (OFF) and then to " " (ON).
3. If the emergency stop switch is pressed during the origin search,
you cannot move the focusing unit even though the emergency
stop switch is rotated to the resetting direction.
To cancel this, while the emergency stop switch is rotated to
the resetting direction, set the main switch of the control box for
motorized to " " (OFF) and then set the main switch to " " (ON)
again. When the error sound (five short beeps) is heard (If you are
using the digital indicator STM7-DI, "013F1507" is displayed on the
display area.), cancel the error according to the procedures in 2.
Height Measurement
1. To measure the height with higher accuracy, use an objective with
high magnification. (50x or higher)
b

8
2. When measuring the height using the autofocus unit, the focusing
unit rises by AF operation. Therefore, the focusing unit may stop
rising because the focusing unit reaches the upper limit of its
movable area.
3. When using the MM6-OB10X, the objective may collide with the
stage before the focusing unit reaches the lower limit of the Z-axis
movable area. Therefore, operate it with careful attention.
4. When using the objective with a working distance less than 5 mm
in combination with the rotatable stage, the objective may collide
with the stage before the focusing unit reaches the upper limit of
the Z-axis movable area. Therefore, set the lower software limit and
operate it carefully.
5. When using the rotatable stages STM7-RS100/STM7-RS200/STM7-
RS300, the Z measurement range will be narrower by the amount of
the rotatable stage height. (30 mm)
6. When using the large frame STM7-LF/STM7-LFA, a specimen whose
height is 100 mm or less can be placed at the position backward
from the light axis by 180 mm or more.
Stage
1. The Y-axis knob of the 50x50 mm stage STM7-CS50 or the 100x100
mm stage STM7-CS100 comes out below the stage-mounting
surface.
When placing the stage on the table, etc., avoid the Y-axis knob
from contacting the table surface.
2. When you purchase a new stage or replace/repair the stage, input
the setting values suitable for the stage again (page 74).
3. When you move the stage by releasing the clutch, hold the
movement knob. (Do not apply the excess load to the X- or Y-axis
knob.)
Adapter to mount measuring objectives
1. While MM6-OB1X is attached, do not attach/detach the adapter to
mount measuring objectives to/from the microscope.
2. Do not attach the BD type of the UIS2 metallurgical objective to the
adapter to mount measuring objectives.
Measurement objective
1. When the MM6-OB1X objective is used in reflected light
illumination, spot-like flare may be observed on the center of
measuring objects with low reflectance.

out-of-focus position. So be careful.
9. When this unit is installed, it may affect the observations as
described below.
• When this unit is combined, the periphery of the observation
field of view may become dark. If this bothers you, replace the
cross-frame part of the eyepiece with that provided with this
unit (page 34).
• Because the observation luminous energies decreases with
this unit, the reflected light DIC observation cannot be used.
Rotatable stage
1. Do not attach the rotatable stage on the stage by reversing front
and back, right and left, and up and down.
2. Use the fine focusing knob (lower right area of the stage top
surface) to rotate the rotatable stage. Do not rotate the rotatable
stage with your hands.
3. Do not rotate the fine focusing knob when the rotatable area is fixed.
4. During carrying the rotatable stage, tighten the rotation clamp knob
(lower left area on the stage top surface) to secure the rotatable area.
5. When carrying the rotatable stage, hold it by putting your hand on
the groove on the side surface of the base of the rotatable stage.
Do not hold any other parts.
Digital camera
1. Use the USB cable provided with the digital camera.
2. Do not connect to ports other than the USB 2.0 port complied with
ENCI (Enhanced Host Controller Interface) standard of the controller.
Otherwise, the operations are not ensured.
3. If the digital camera is used in a high temperature environment, the
noise on the image will be increased.
4. Using the digital camera will increase the load on the controller. The
longer the camera exposure time is, the slower the frame rate and
the application operations become.
(When using the microscope digital camera, refer to the instruction
manual provided with DP22/DP27.)

Repair and movement of the system
1. The assembly and setup are performed by the Olympus dealer.
Do not repair or move the microscope by yourself. If you want to
move the microscope, consult an Olympus sales office. If repairing
or moving the microscope by you should cause the microscope
to malfunction or be damaged, Olympus shall not be liable for the
consequence. Even if the consequence occurs during the warranty
period, the service may have to be chargeable.
2. Do not carry the microscope without the dedicated transport tools or
packaging materials. Otherwise, the accuracy is not ensured.
• Be sure to carry the microscope carefully only by those who
understand the transportation cautions (described in the
instruction manual).
• Those who install the microscope must read the descriptions
in the instruction manual and understand the installation
procedures.
3. When transporting the STM7, be sure to use the dedicated
transporting tools and packing materials. Consult your local
Olympus representative for details.
4. When transporting, be sure to use the Z-axis transport lock and
clamps/screws. Even though the clutch of the stage is fixed, if the
stage is tilted significantly, the stage will be moved, which is very
dangerous.
5. Relocating the microscope overseas by you without notifying
Olympus in advance will not allow you to enjoy the service in the
country where the microscope was relocated.
6. If you relocate the microscope overseas, note the following matters:
• The power cords must be replaced with ones that can be
used in your destination.
• Confirm that the device is conformed to the laws and
regulations of the relocation destination.
• Some countries and regions have not established the
Olympus service system. Contact Olympus for details.
• Not all the countries and regions with the Olympus service
system provide their after-sales services under the same
conditions as those in your country.
Certificate of Accuracy
1. Do not lose Certificate of Accuracy. The setting values of factory
default values (accuracy assurance) are described in Certificate of
Accuracy.

1. Do not leave stains or fingerprints on the lenses. If they get dirty,
blow away dust with a commercially available blower and gently
wipe the lens or filter with a piece of cleaning paper (or clean
gauze).
For cleaning fingerprints and oil stains, slightly moisten a piece of
cleaning paper with commercially available absolute alcohol and
wipe them off with it.
Since the absolute alcohol is highly flammable, it must
be handled carefully. Be sure to keep it away from open
flames or potential sources of electrical sparks – for
example, electrical equipment that is being switched on
or off, which could cause ignition of a fire.
Also, remember to always use absolute alcohol only in a
well-ventilated room.
2. Do not use organic solvents, which cause painted and plastic
parts to deteriorate. Do not use organic solvents to clean device
components other than the glass components. To clean them,
use a lint-free, soft cloth slightly moistened with a diluted neutral
detergent.
3. When cleaning the base unit of the frame, use the cleaner
dedicated to the stone surface plate.
4. After use, return the stage to the center position and lock the clutch
to maintain the stage accuracy. And do not place a heavy object on
the stage.
5. After using the system, set the main switch to " " (OFF), wait for the
control box and power supply unit to cool down sufficiently, and
keep it covered with a dust cover during storage.
Recommended cover (Option): COVER-022
6. After using the system, return the stage to the center position and fix
the clutch levers. Do not place a heavy object on the stage.
7. Avoid using or storing the equipment under direct sunlight, high
temperature (over 40 °C), high humidity, excessive dust or vibrations.
8. Do not bend extremely, pull or step on the cables. Also take special
care in its distribution.
9. Never oil the XYZ guide a.
10. Before disposing of this product, be sure to follow the regulations
and rules of your local government.
