Failure to comply with the precautions below could lead to injury or death or damage
to the instrument.
WARNING
• Use the Instrument Only for Its Intended Purpose
This instrument is equipped with current and voltage measurement.
Use the instrument only for measuring and generating current and voltage.
• Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
• 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 must be plugged into an outlet with a protective earth
terminal. Do not disable this protection by using an extension cord without
protective earth grounding.
• Additionally, do not use the power cord supplied with this instrument with
another instrument.
• Do not use the power cord in a bundled condition.
• If you use a power plug with foreign substance on it, insulation may be
compromised by humidity or other factors and may cause a fire. Clean the
power plug regularly.
• Connect the Protective Grounding Terminal
Make sure to connect the protective earth to prevent electric shock before
turning ON the power. The power cord that comes with the instrument is a three-
prong type power cord. Connect the power cord to a properly grounded three-
prong outlet.
• 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 poses a potential shock
hazard.
• Do Not Use When the Protection Functions Are Defective
Before using this instrument, check that the protection functions, such as the
protective grounding and fuse, are working properly. If you suspect a defect, do
not use the instrument.
• Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors.
Operation in such an environment constitutes a safety hazard.
• Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel may remove the covers and disassemble
or alter the instrument. The inside of the instrument is dangerous because parts
of it have high voltages.
