Do not place this instrument in an unstable location such as on an unsteady stand or
an inclined place.
If the instrument is placed in an unstable location, it may fall or topple over, resulting in electric
shock, fire or injury. If this instrument falls or its cover is damaged, after the power switch has
been put in the OFF position, and the power plug has been disconnected from the power
outlet, and contact your nearest YOKOGAWA dealer.
Be careful when taking high-voltage measurements.
Coming into contact with high voltages during measurements may result in electric shock.
Except for the input terminal for measurement on the front of this instrument, always
connect the grounding line of the input connector of this instrument to the ground
potential level (ground) of the object to be measured.
If the grounding line of the above-mentioned input connector of this instrument is connected
to a level other than the ground level of the object to be measured, this may result in electric
shock (damage to the object to be measured, this instrument, or other connected devices).
Always use a 3-prong power cord
Failing to use a 3-prong power cord may result in electric shock, fire, or malfunction.
When supplying power via a three-wire power outlet using the 3-prong power cord accessory,
ground the cord using the ground wire.
Always use a 3-prong power cord compatible with the power voltage.
Using a power cord that is incompatible with the power voltage may result in fire or
malfunction.
Do not use the power cord provided with instrument for other products.
In accordance with electrical safety regulations, the power cord provided with this instrument
is not to be used with other electrical equipment.
Use the instrument at a rated supply voltage.
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. The power supply voltages that can be used are shown in Table 1. The center voltages
are displayed near the AC LINE INPUT on the rear panel.

Do not touch the input terminal mid operation.
Touching the input terminal mid operation may result in electric shock.
Follow the rules below when handling the power cord.
Failing to follow these rules may result in electric shock, fire, or malfunction. If the power cord
is damaged, contact your nearest YOKOGAWA dealer.
• Do not attempt to modify the power cord.
• Do not forcibly bend the power cord.
• Do not twist the power cord.
• Do not bind the power cord.
• Do not yank the power cord.
• Do not heat the power cord.
• Do not allow the power cord to become wet.
• Do not place heavy objects on top of the power cord.
