Precautions During Use

Safety Precautions

When you are using this instrument, read the “Safety Precautions” given on page 5 thoroughly,
as well as the following points:

Do not remove the cover from the instrument

Some parts of the instrument use high voltages, which 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.

In case of irregularity

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 dealer or the
nearest YOKOGAWA representative, as listed on the back cover of this manual.

Power cord

Nothing should be placed on the power cord; also, 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 2 for the part number to use when placing an order.

General Handling Precautions

Observe the following precautions when handling the instrument.

Never place anything on top of the instrument

Never place other equipment or objects containing water on top of the instrument, otherwise a
breakdown may occur.

Do not cause shock to the input connectors or probes

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 screen

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.

When the instrument is not going to be used for a long period, unplug the power
cord from the AC outlet

When moving the instrument

Disconnect the power cord and connecting cables. Always carry the instrument by the handles
as shown below.

Cleaning

When cleaning the case or the operation panel, unplug the power cord from the plug first, then
wipe with a dry, soft, clean cloth. Do not use volatile chemicals such as benzene or thinner for
cleaning, as this may lead to discoloration or deformation.
