If you are using this instrument for the first time, make sure to thoroughly read the safety
precautions given on page v.
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 or 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
YOKOGAWA 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 iii for the part number when placing an order.
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 to the Input Section
Vibration or shock 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.
