Making Preparations for Measurements
2.1 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 xii.
Do Not Remove the Case
Do not remove the case from the instrument. Some parts of the instrument use 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. Then, contact your nearest YOKOGAWA dealer.
Use the AC Adapter and Power Cord Correctly
Do not place objects on top of the AC adapter or power cord, and keep them away from heat sources.
When unplugging the power cord from the outlet, do not pull on the cord. Pull from the plug.
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. Applying shock to the input
connectors, probes, and the like, can cause electrical noise to enter the instrument through the signal
lines.
Do Not Damage the LCD
Because the LCD 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 of the AC adapter from the outlet.
• Remove the battery pack from the main unit.
