If you are using this instrument for the first time, make sure to thoroughly read the
“Safety Precautions” given on pages v to vi.
Do not remove the cover from the instrument
Some sections inside the instrument have high voltages that are extremely
dangerous. For internal inspection or adjustment, contact your dealer.
Abnormal Symptoms
Never continue to use the instrument if there are any symptoms of trouble such as
strange smells or smoke coming from the instrument. In such cases, immediately turn
OFF the power and unplug the power cord. Also, turn OFF all devices under
measurement that are connected to the input terminals. Then, contact your dealer.
Power cord
Nothing should be placed on top of the power cord. The power cord should also be
kept away from any heat sources. When unplugging the power cord from the outlet,
never pull the cord itself. Always hold the plug and pull it. If the power cord is
damaged, contact your dealer for replacement. Refer to page ii for the part number
when placing an order.
General Handling Precautions
Never place anything on top of the instrument.
Never place another instrument or any objects containing water on top of the
instrument. This may cause problems.
Keep electrically charged objects away from the instrument.
Keep electrically charged objects away from the input terminals. They may damage
the internal circuits.
Do not damage the LCD
The LCD is very vulnerable to scratches. Therefore, be careful not to damage the
surface with sharp objects. Also, do not apply vibration or shock to it.
When not using the instrument for a long time
When the instrument is not being used for an extended period of time, unplug the
power cord from the outlet.

Cleaning

measurement and the instrument and remove the instrument’s power cord from the
outlet. Then, wipe with a dry, soft cloth. Do not use volatile chemicals since this
might cause discoloring and deformation.
