WARNING
1. Purpose of system
This system is a precision optical measuring system. Do not use it for any purpose other
than measurement and observation. The controller for this system was developed
specifically for this system; do not use it for any other purpose.
2. Do not disassemble the system
Never attempt to disassemble this system except as specifically instructed in this instruction
manual. Attempting to disassemble the system could harm the performance of the system,
and also carries a risk of electric shock and injury.
The zoom head, guide, and scale are adjusted at the factory with extreme precision, so
never attempt to disassemble them. If you notice a problem, contact your nearest Nikon
representative.
3. Turn off the power when connecting or disconnecting cables
When connecting or disconnecting any of the cables, always turning off the power and
unplug the power cord first to prevent any possible electric shock.
Before turning off the power, be sure to first close any programs that may be running.
4. Emergency stop
In a case of emergency, press the yellow STOP switch located on the top right of the joystick
box. The system stops immediately.
To recover from an emergency stop, turn the power off, clear the condition that necessitated
the emergency stop, and then restart the system.
5. Mass of the workpiece
The maximum mass that may be placed on the stage is 15 kg. Never exceed the maximum
permissible mass, taking into consideration not only the mass of the workpiece but also the
mass of the clamps, etc. Exceeding the maximum permissible mass could cause the stage
glass to break, which could result in serious injury or a major accident.
6. System Setup
Moving the system creates a risk that the system may tip over and cause injuries. Always
contact your Nikon representative before moving the system. Otherwise, Nikon shall not bear
responsibility for any accidents or damage that occur while the system is being moved.
(However, you can move the system if there is no ridge or slope in level along the path over
which the system is to be moved. Be certain that you have read page 7 and understand all of
the warnings and cautions described therein before attempting to move the system.)

CAUTION
1. Confirm the input voltage
• Before plugging in the power cord, confirm that the input voltage indications on the host
computer and the display (located on labels near the power receptacles) match the supply
voltage that is being used.
If the input voltage is not identical to the supply voltage, do not attempt to connect the
power but contact your nearest Nikon representative. Using the incorrect supply voltage
could cause a malfunction, fire, or electric shock.
• The input voltage for the VMA-2520 automatically switches within 100 - 240 V~, 50/60Hz.
The power supply receptacle is located on the rear of the controller.
• Always plug the power cords for this system (including the VMA-2520, the computer, and
the computer display) into a grounded three-conductor outlet. Improper grounding can
result in electric shock or abnormal operation.
• Always be sure to turn OFF all of the power switches before plugging in the power cords.
2. Do not touch moving parts
Do not touch any moving parts, as these parts can trap your hands or fingers.
3. Cautions concerning heat from the controller
Note that the internal parts of the controller are extremely hot during and immediately after
equipment operation.
• Do not bring highly flammable materials (gasoline, benzene, paint thinner, alcohol, etc.),
cloth or paper near the controller. Doing so could start a fire.
• There are ventilation openings for a cooling fan on the rear of the controller. In order to
allow the adequate dissipation of heat, install the controller so that there is an open space
of at least 20 cm between the rear panel of the controller and the nearest wall. Do not
obstruct the ventilation openings on the front of the controller.

Cautions Concerning Use
1. Installation Location
To avoid mis-operation and to peform safe and precise measurement, be sure to observe the
following points when installing this system. Be especially careful not to pinch your fingers, etc.,
when installing the system.
• Install the system in a clean environment. Dust and oily vapors can have a clear and adverse
impact on the performance of the system. Dirt and corrosion on the guide surfaces of the stage
in particular can cause a deterioration in the precision of the system.
• Install the system in a location where the temperature ranges from 10 to 35 °C and where the
humidity is less than 70%. Installation in a hot, humid location can result in condensation and
malfunctions.
• Install the system in a controlled temperature environment (i.e., an environment that is not
subject to rapid changes in temperature). Temperature changes can cause measurement errors.
• Before selecting the installation location, study the requirements described on page 17.
• Install the system in a location with little vibration.
• Install the system in a location that is not subject to sudden voltage fluctuations or electronic
noise.
• If the ventilation holes for the cooling fan in the controller are blocked, a malfunction or fire
could result.
• Install the controller so that there is an open space of at least 20 cm between the rear panel of
the controller and the nearest wall. Do not obstruct the ventilation openings on the front of the
controller.
• Make sure that the main body and the side of the measurement stand are at least 20 cm away
from the nearest wall. When setting up a personal computer rack or other equipment next to
the main body or the side of the measurement stand, also provide a space of at least 20 cm.
Failure to follow this instruction may lead to the risk of collision between the stage and a wall or
object.
2. Handle carefully
This system is a precision instrument that requires careful handling. Striking the system or
operating it in a reckless manner could damage the system.
3. Measurement and temperature
Generally, the dimensions of a workpiece will change according to the temperature. (The amount
of change depends on a coefficient that is inherent to the material.) The operation of this system
is guaranteed over a wide temperature range, but in order to obtain stable and reproducible
measurement results, the system should be used in an adequately controlled temperature
environment with less temperature change. In addition, when using this system for the first time,
be sure that you have allowed the system to become fully adjusted to the temperature
environment. (Usually, this simply requires leaving the system in that temperature environment for
about 24 hours.)
4. Measurement stand
The main body comes with a special measurement stand. If the special measurement stand is not
used, be sure to use a stand with sufficient strength and rigidity. If a general-purpose working
table is used, make sure it can withstand 1,000 kg of uniformly distributed load or more.

- vii -
5. Z-axis motion prat
Do not let the optical head or the LEDs collide with the workpiece or the clamps. If there is a
collision, press the STOP switch, turn off the power, and then remove the cause of the collision.
After restarting the system, even if it appears that everything is operating normally, be sure to
“calibrate the optical head” and “check the Laser Autofocus focal position offset”. We also
recommend that you have your nearest Nikon representative to inspect the system.
6. USB and IEEE1394 setting
Do not connect the supplied USB cable and IEEE1394 cable before the iNEXIV software is
installed. If the cable is connected before the installation of the software, the device driver may not
be set correctly.
The iNEXIV software can be used only when the appropriate driver is detected and installed when
the cable is connected for the first time according to the instructions provided during the software
installation.
7. Cleaning finished surfaces and plastic components
We recommend using a silicone cloth to clean finished surfaces and plastic components. If a
surface is especially dirty, wipe it with a dilute, mild detergent. Do not use solvents (such as paint
thinner, alcohol, or ether).
8. Isolation from the power supply
The weak electric power is running through the system even when its power switch is turned off.
In the following conditions, be sure to unplug the power cord from the power outlet.
• When the system is not used for a long period of time.
• When you wish to isolate the system from the power source.
• In case of malfunction.
