WARNING
• Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the power
supply before turning ON the power.
• Connect the Protective Grounding Terminal
Make sure to connect the protective grounding to prevent
electric shock before turning ON the power.
• Do Not Impair the Protective Grounding
Never cut off the internal or external protective grounding wire or
disconnect the wiring of the protective grounding terminal. Doing
so invalidates the protective functions of the instrument and
poses a potential shock hazard.

Do not operate the instrument if the protective grounding might
be defective. Also, make sure to check them before operation.

2
S, SOx, etc.)
will cause a malfunction.

Handling Precautions of the FX
• Use care when cleaning this instrument, especially its plastic
parts. Use a soft dry cloth. Do not use organic solvents, such
as benzene or thinner, or other cleansers. They may cause
discoloring and deformation.
• Keep electrically charged objects away from the signal terminals.
If you do, the FX may malfunction.
• Do not apply volatile chemicals to the display, panel keys, etc.
Do not allow rubber and vinyl products to remain in contact
with the FX for long periods of time. If you do, the FX may
malfunction.
• When not in use, make sure to turn OFF the power switch.
• If there are any symptoms of trouble such as strange odors or
smoke coming from the FX, immediately turn OFF the power
switch and the power supply source. Then, contact your nearest
YOKOGAWA dealer.
Handling Precautions of the External Storage
Medium (CF Card)
• Use caution in the handling of the external storage medium as it
is a delicate product.
• Write operation to storage media may fail under high-
temperature or low-temperature environments. If you are using
the FX in a low-temperature environment (around 10 °C or
less), use the FX after the warm-up time (at least 30 minutes)
has elapsed. If you are using the FX under a high-temperature
environment (around 40 °C or more), it is recommended that the
external storage medium be inserted into the drive when saving
the data and be removed after the data storage operation is
finished.
• Remove the storage medium from the drive when turning the FX
ON/OFF.
• Touching the compact flash section when static electricity is built
up on the human body can lead to erroneous operation.
• For the general handling precautions of the external storage
medium, see the instruction manual that came with the external
storage medium.
CAUTION
• Do not access the storage medium in a place with vibrations or
shock. The storage medium or drive may malfunction.
