Precautions During Use
Safety Precautions
• If you are using this instrument for the first time, make sure to thoroughly read
the safety precautions given on page 2.
• Do not remove the cover from the instrument.
Some parts of the instrument carry high voltages and are extremely
dangerous. When the instrument needs internal inspection or adjustment,
contact your dealer or nearest YOKOGAWA representative as listed on the
back cover of this manual.
• If you notice smoke or unusual odors coming from the instrument, turn both
the POWER and MAIN POWER switches OFF and unplug the power cord
immediately. Also turn OFF the power to the measuring object connected
to the input section of the instrument. Contact your dealer or nearest
YOKOGAWA representative as listed on the back cover of this manual.
• Nothing should be placed on the power cord, and it should be kept away
from any heat sources. When unplugging the power cord from the AC outlet,
never pull the cord itself. Always hold the plug and pull it. If the power cord
is damaged, contact your dealer. Refer to page 5 for the part number to
reference when placing an order.
General Handling Precautions
• When moving the instrument, disconnect the power cord and connecting
cables. Always carry the instrument by the handle located on the left side of
the instrument.
• Keep electrically charged objects away from the input or output terminals.
They may damage the internal circuits.
• Do not allow volatile chemicals, or rubber or vinyl products to come into
contact with the case or operation panel for prolonged periods. Doing so may
result in discoloration.
• Take care not to allow any hot items such as a soldering iron to come into
contact with the operation panel.
• When the instrument is not going to be used for a long period, unplug the
power cord from the AC outlet.
• For precautions when handling the battery pack, refer to page 39, “Battery
Pack (Optional).”
• When removing dirt from the case or operation panel, first remove the power
cord, then use a clean, dry cloth to gently wipe the external surfaces of the
instrument. Do not use any solvents such as benzene or paint thinner. Doing
so might cause discoloration or deformation.
