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 a waveform measuring device that monitors and measures electrical
signals. Do not use this instrument for anything other than as a waveform measuring device.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power supply
First, ensure that the source voltage matches the rated supply voltage of the instrument and
that it is within the maximum rated voltage of the power cord you will use. Then connect the
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 for the
instrument. The main power plug must be plugged into an outlet with a protective earth
terminal. Do not invalidate this protection by using an extension cord without protective earth
grounding. Further, do not use this power cord with other instruments.
Connect the Protective Ground Terminal
Be sure to connect the protective earth to prevent electric shock before turning ON the power.
The power cord that you can use for the instrument is a three-prong 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 earth wire or disconnect the wiring of the
protective earth terminal. Doing so may result in electric shock or damage to the instrument.
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 gases or vapors. Doing so is
extremely dangerous.
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.
Accessories
Use the accessories specified in this manual. Moreover, use the accessories of this product
only with Yokogawa products that specify them as accessories. Do not use faulty accessories.
