PREPARATION FOR USE
SAFETY
This part
of
the manual tells how to prepare for
and
to
proceed with the initial start-up of the instrument.
Refer
to
the Safety Summary at the front of this
manual for power source, grounding,
and
other safety con-
siderations pertaining
to
the use of the instrument. Before
connecting the oscilloscope to a power source, read
entirely both this section
and
the Safety Summary.
LINE VOLTAGE
This instrument
is
capable of continuous operation with
input voltages that range from 90 V to 250 V with source
voltage frequencies from 48
Hz
to 440 Hz.
POWER CORD
A detachable three-wire power cord with a three-
contact plug
is
provided with each instrument for connect-
ing to both the power source
and
protective ground.
The
power cord may
be
secured to the rear panel
by
a cord-
set-securing clamp
(see
Figure
2-1
).
The protective-ground
contact
in
the plug connects (through the protective-
ground conductor) to the accessible metal parts of the
instrument. For electrical-shock protection, insert this plug
only into a power-source outlet that has a properly
grounded protective-ground contact.
Instruments
are
shipped with the power cord specified
by the customer. Available power-cord information
is
presented
in
Figure 2-2,
and
part numbers are listed
in
"Options
and
Accessories" (Section
7).
Contact your
Tektronix representative or local Tektronix
Field
Office for
additional power-cord information.
