Precautions During Use
Safety Precautions
When using this instrument, thoroughly read the “Safety Precautions” given on page 4 and
5. In addition, pay attention to 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.
Unusual occurrences
If you notice smoke or unusual odors coming from the instrument, turn OFF the power and
unplug the power cord immediately. 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 quote 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,
otherwise a breakdown may occur.
Do not subject the input terminals or connecting cables to shock
Shock to the input terminals or connecting cables may turn into electrical noise and enter
the instrument via the signal lines.
When the instrument is not going to be used for a long period
Unplug the power cord from the AC outlet.
CRT Screen
It is recommended to use weak contrast settings so as not to burn in the screen.
When moving the instrument
Disconnect the power cord and connecting cables.
Always carry the instrument by the handles or carry it
with both hands as shown on the right.
Note that the chart paper might show some
discoloration due to friction after the instrument is
moved with the roll paper installed. In such a case,
we recommend to remove and re-install the chart
paper again. For details on the procedure, refer to
page 10-1.
Cleaning
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.
