OPERATING INFORMATION
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.
