Handling Precautions

Safety Precautions
If you are using this instrument for the first time, make sure to thoroughly read the safety precautions
given on page xiii.
Do Not Remove the Case
Do not remove the case from the instrument. Some sections inside the instrument have high
voltages and are extremely dangerous. For internal inspection and adjustment, contact your nearest
YOKOGAWA dealer.
Unplug If Abnormal Behavior Occurs
If you notice smoke or unusual odors coming from the instrument, immediately turn off the power and
unplug the power cord. If such an irregularity occurs, contact your dealer.
Do Not Damage the Power Cord
Nothing should be placed on the power cord. The cord should be kept away from any heat sources.
When unplugging the power cord from the outlet, never pull by the cord itself. Always hold and pull by
the plug. If the power cord is damaged, contact your dealer for replacement. Refer to page vi for the
part number to use when placing an order.
General Handling Precautions
Do Not Place Objects on Top of the Instrument
Never place other instruments or objects containing water on top of the instrument, otherwise a
breakdown may occur.
Do Not Apply Shock or Vibration
Do not apply shock or vibration. Doing so may damage the instrument. Extra caution is needed for
the optional internal hard disk, because it is sensitive to vibration and shock. Shocks to the input
connectors or probes may turn into electrical noise and enter the instrument via the signal lines.
Do Not Damage the LCD
Since the LCD screen is very vulnerable and can be easily scratched, do not allow any sharp objects
near it. Also it should not be exposed to vibrations and shocks.
Unplug during Extended Non-Use
Unplug the power cord from the outlet.
