IM 704610-01E
Make sure to take the following precautions. Failure to take these precautions might
result in injury or death of personnel.
WARNING
• Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the instrument and that it is within the maximum rated
voltage of the provided power cord.
•Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug can only be plugged into an
outlet with a protective grounding terminal. Do not disable the protection feature
of the instrument by using an extension cord without protective grounding.
•Connect the Protective Grounding
Make sure to connect the protective grounding to prevent electric shock before
turning ON the power. The power cord included with this instrument is a 3-prong
cord with a grounding wire. Connect the power cord to a 3-prong AC outlet with
a protective grounding terminal.
•Do Not Impair the Protective Grounding
Never cut off the internal or external protective grounding wire or disconnect the
wiring from the protective grounding terminal. Doing so creates a potential shock
hazard.
•Do Not Operate with Defective Protective Grounding or Fuse
Never operate the instrument if you suspect the protective grounding or fuse
might be defective. Make sure to check them before operation.
• Use the Correct Fuse
To prevent fire, make sure to use fuses of the specified rating for voltage,
current, and type. Make sure to turn OFF the instrument and unplug the power
cord before replacing the fuse. Never short the fuse holder.
•Do Not Operate Near Flammable Materials
Do not operate the instrument in the presence of flammable liquids or vapors.
Operation of any electrical instrument in such an environment constitutes a
safety hazard.
•Do Not Use When Removed from the Case
The cover should be removed by qualified personnel only. There are some
areas inside the instrument with high voltages.
•Ground the Instrument before Making External Connections
Connect the protective grounding before connecting to the item under
measurement or external control circuits. Also, If you need to touch the circuit
with your hand, first cut the power to the circuit and confirm that it contains no
voltage. To prevent the possibility of electric shock or an accident, connect the
ground of the probe and input connector to the ground of the item being
measured.
See below for operating environment limitations.
CAUTION
This product is a Class A (for industrial environments) product. Operation of this
