• Before using the instrument for the first time, make sure you have read the safety
precautions on pages iv and v.
• Do not remove the case from the instrument. Some areas in the instrument use high
voltages, which are extremely dangerous. When the instrument needs internal
inspection or adjustment, contact your nearest YOKOGAWA representative.
Addresses may be found on the back cover of this manual.
• If you notice smoke or unusual odors coming from the instrument, immediately turn
OFF the power and unplug the power cord. Also turn OFF the power to all the objects
being measured that are connected to the input terminals. If such an irregularity
occurs, contact your nearest YOKOGAWA representative. Addresses may be found
on the back cover of this manual.
• Do not place anything on the power cord and keep it away from any heat generating
articles. When unplugging the power cord from the power outlet, always hold the plug
and pull it, never pull the cord itself. If the power cord becomes damaged, contact
your nearest YOKOGAWA representative. Addresses may be found on the back
cover of this manual.Refer to page ii for the part number of the appropriate power cord
when placing an order.
• Never place anything on top of the instrument, especially objects containing water.
Entry of water into the instrument may result in breakdowns.
• When Moving the Instrument, first turn off the power of the objects to be measured
and disconnect the connected cables such as for measurement and communication.
Then turn off the power switch and unplug the power cord from the power outlet.
Always carry the instrument by the handles as shown below.
• To prevent internal temperature rise, do not block the vent holes in the instrument
case.
• Keep input terminals away from electrically charged articles as they may damage
internal circuits.
• Do not allow volatile chemicals to come into contact with the case or operation panel.
Also do not leave any rubber or vinyl products in contact with them for prolonged
periods. The operation panel is made of thermoplastic resin, so take care not to allow
any heated articles such as a soldering iron to come in contact with it.
• For cleaning the case and the operation panel, unplug the power cord first, then
gently wipe with a dry, soft and clean cloth. Do not use chemicals such as benzene
or thinner, since these may cause discoloration or damage.
• If the instrument will not be used for a long period, unplug the power cord from the AC
outlet.
