OPERATING INSTRUCTIONS
PREPARATION FOR USE
SAFETY
Refer to the “Operators Safety Summary" at the front of
this manual for power source, grounding, and other safety
considerations pertaining to the use of the 2215A. Before
connecting the instrument to a power source, carefully read
the following about line voltages, power cords, and fuses.
LINE VOLTAGE
The instrument is capable of continuous operation using
input voltages that range from 90 V to 250 V nominal at
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 to permit connection
to both the power source and protective ground. The plug
protective-ground contact connects (through the protective-
ground conductor) to the accessible metal parts of the in
strument. For electrical-shock protection, insert this plug
only into a power outlet that has a securely grounded pro
tective-ground contact.
Instruments are shipped with the required power cord as
ordered by the customer. Available power-cord information
is illustrated in Figure 2-1, and part numbers are listed on
the “Accessories" page at the back of this manual. Contact
your Tektronix representative or local Tektronix Field Office
for additional power-cord information.
LINE FUSE
The instrument fuse holder is located on the rear panel
(see Figure 2-2) and contains the line fuse. The following
procedure can be used to verify that the proper fuse is in
stalled or to install a replacement fuse.
