Section 2 Before Use
2-6
WARNING
Always connect the instrument to a properly grounded
outlet. Do not use the instrument with an extension cord or
transformer that does not have a ground wire.
If the instrument is connected to an ungrounded outlet,
there is a risk of receiving a fatal electric shock. In
addition, the peripheral devices connected to the
instrument may be damaged.
Unless otherwise specified, the signal-connector ground
terminal, like an external conductor of the coaxial
connector, of the instrument is properly grounded when
connecting the power cord to a grounded outlet. Connect
the ground terminal of DUT to a ground having the same
potential before connecting with the instrument. Failure to
do so may result in an electric shock, fire, failure, or
malfunction.
CAUTION
If an emergency arises causing the instrument to fail or
malfunction, disconnect the instrument from the power
supply by either turning off the main power switch on the
front panel (switch to the (O) side), or by disconnecting
either end of the power cord.
When installing the instrument, place the instrument so
that an operator may easily operate the main power
switch.
If the instrument is mounted in a rack, a power switch for
the rack or a circuit breaker may be used for power
disconnection.
