USING THE PRODUCT SAFELY
■Preface
To use the product safely, read this instruction manual to the end.
Before using this product, understand how to correctly use it.
If you read this manual but you do not understand how to use it, please
ask us or your local dealer. After you read this manual, save it so that
you can read it, anytime as requied.
■Pictorial indication
This instruction manual and product show the warning and caution items
required to safely use the product. The following pictorial indication and
warning character indication are provided.
<Pictorial indication>
Some part of this product or the instruction
manual may shows this pictorial indication. In
this case, if the product is incorrectly used in that
part, a serious danger may be brought about on
the user’s body or the product.
To use the part with this pictorial indication, be
sure to refer to this instruction manual.
WARNING
!
If you use the product, ignoring this indication,
you may get killed or seriously injured. This
indication shows that the warning item to avoid
the danger is provided.
CAUTION
!
If you incorrectly use the product, ignoring this
indication, you may get slightly injured or the
product may be damaged. This indication shows
that the caution item to avoid the danger is
provided.
Please be informed that we are not responsible for any damages to the user
or to the third person, arising from malfunctions or other failures due to
wrong use of the product or incorrect operation, except such responsibility
for damages as required by law.

II
USING THE PRODUCT SAFELY
WARNING
!
CAUTION
!
■Do not remove the product’s covers and panels
Never remove the product’s covers and panels for any purpose.
Otherwise, the user’s electric shock or fire may be incurred.
■Warning on using the product
Warning items given below are to avoid danger to user’s body and life and
avoid the damage or deterioration of the product.
Use the product, observing the following warning andcaution items.
■Warning items on power supply
●Power supply voltage
The rated power supply voltages of the product are 100, 120, 220
and 240VAC. The rated power supply voltage for each product
should be confirmed by reading the label attached on the back of
the product or by the “rated” column shown in this instruction manual.
The specification of power cord attached to the products is rated to
125VAC for all products which are designed to be used in the
areas where commercial power supply voltage is not higher than
125VAC. Accordingly, you must change the power cord if you want
to use the product at the power supply voltage higher than 125VAC.
If you use the product without changing power cord to 250VAC
rated one, electric shock or fire may be caused.
When you used the product equipped with power supply voltage
switching system, please refer to the corresponding chapter in the
instruction manuals of each product.
●Power cord
(Important) The attached power cord set can be used for this
device only.
If the attached power cord is damaged, stop using the product and
call us or your local dealer. If the power cord is used without the
damage being removed, an electric shock or fire may be caused.
●Protective fuse
If an input protective fuse is blown, the product does not operate. For a
product with external fuse holder, the fuse may be replaced. As for
how to replace the fuse, refer to the corresponding chapter in this
instruction manual.
If no fuse replacement procedures are indicated, the user is not
permitted to replace it. In such case, keep the case closed and
consult us or your local dealer. If the fuse is incorrectly replaced, a
fire may occur.

III
USING THE PRODUCT SAFELY
■Warning item on Grounding
If the product has the GND terminal on the front or rear panel surface,
be sure to ground the product to safely use it.
■Warnings on Installation environment
●Operating temperature and humidity
Use the product within the operating temperature indicated in the
“rating” temperature column. If the product is used with the vents of
the product blocked or in high ambient temperatures, a fire may occur.
Use the product within the operating humidity indicated in the “rating”
humidity column. Watch out for condensation by a sharp humidity
change such as transfer to a room with a different humidity. Also, do
not operate the product with wet hands. Otherwise, an electric shock
or fire may occur.
●Use in gas
Use in and around a place where an inflammable or explosive gas or
steam is generated or stored may result in an explosion and fire. Do
not operate the product in such an environment.
Also, use in and around a place where a corrosive gas is generated or
spreading causes a serious damage to the product. Do not operate
the product in such an environment.
●Installation place
Avoid installing the product on inclined places or on places subject to
vibration. Otherwise, the product may slip or fall down to cause
damages or injury accidents.
■Do not let foreign matter in
Do not insert metal and inflammable materials into the product from its
vent and spill water on it. Otherwise, electric shock or fire may occur.
■Warning item on abnormality while in use
In abnormal situations, such as “smoke”, “fire”, “abnormal smell” or
“irregular noise” occur from the product while in use, stop using the
product, turn off the switch, and remove the power cord plug from the
outlet. After confirming that no other devices catch fire, ask us or your
local dealer.

IV
USING THE PRODUCT SAFELY
■Warning Item for the Measurement
●When you measure a part of a high voltage, be careful not to touch a
hand to a measurement part directly. There is a risk of an electric shock.
●Be sure to connectthe probe or the cable and the groundside of the input
connector to the ground potential (ground) of the substance measured.
Since the chassis of this instrument is connected to the ground of the
input block, connecting the earth lead of the probe to the potential
floating from the ground potential may result in the following:
Electric shock
A high current flows and damages the substance measured, this
instrument, and other connected device.
The following parts are connected to the chassis:
Probe for each channel and ground side of the input BNC connector
Grounding conductor of the accessory 3-core power cord
Ground pin for an interface signal
“Bad example” Prohibition
When measuring the floating potential, a differential method of
measurement is recommended ( refer to the figure below ).
“Good example”
At connecting as Bad
Example, +90V and chassis
are shorted, and damages
substance a measured.
Therefore do not make such
connection.
If the instrument is not
grounded, a potential of the
chassis is +90V.
Ground a chassis, in order to
prevent an electric shock
accident.

USING THE PRODUCT SAFELY
■Input / Output terminals
Maximum input to terminal is specified to prevent the product
from being damaged. Do not supply input, exceeding the
specifications that are indicated in the "Rating" column in the
instruction manual of the product.
Also, do not supply power to the output terminals from the
outside.
Otherwise, a product failure is caused.
■Calibration
Although the performance and specifications of the product are
checked under strict quality control during shipment from the factory,
they may be deviated more or less by deterioration of parts due to their
aging or others.
It is recommended to periodically calibrate the product so that it is used
with its performance and specifications stable.
For consultation about the product calibration, ask us or your local
dealer.
■Daily Maintenance
When you clean off the dirt of the product covers, panels, and
knobs, avoid solvents such as thinner and benzene. Otherwise, the
paint may peel off or resin surface may be affected.
To wipe off the covers, panels, and knobs, use a soft cloth with neutral
detergent in it. During cleaning, be careful that water, detergent, or
other foreign matters do not get into the product.
If a liquid or metal gets into the product, an electric shock and fire are
caused. During cleaning, remove the power cord plug from the outlet.
Use the product correctly and safely, observing the above warning and
caution items. Because the instruction manual indicates caution items even
in individual items, observe those caution items to correctly use the product.
If you have questions or comments about the instruction manual, ask us or
E-Mail us.
