Section 1—5110
OPERATING INSTRUCTIONS
This instruction manual provides both operating and
servicing information for the 5110 Oscilloscope. The
manual is divided into nine sections. Operating, specifica­
tion, and performance check information is covered in the
first two sections, and is intended for operating and
service personnel. Servicing information is covered in the
remaining sections of the manual, and is intended for
qualified service personnel only.
OPERATING POWER
This instrument can be operated from eithera 120-volt
or240-volt nominal line-voltage source, 48 to 440 hertz. In
addition, three regulating ranges are
provided for each
nominal line-voltage source.
PRELIMINARY
INFORMATION
Oscilloscope Features
The oscilloscope is a solid state, light weight instru­
ment designed for general-purpose measuring
applications. This instrument has three plug-in com­
partments that accept plug-in units to form a complete
measurement system. The two-plug-in compartments on
the left are connected to the vertical deflection system.
The right plug-in compartment is connected to the
horizontal deflection system. Electronic switching
between the vertical plug-in compartments allows a multi­
trace vertical display. The flexibility of this plug-in feature
and the variety of plug-in units available allow this system
to be used for many measurement applications.
This instrument features a large-screen, 8X10 division
display; each division equals 0.5 inch (1.27 centimeter).
Regulated d c power supplies ensure that performance is
not affected by variations in line voltage and frequency, or
by changes in the load due to the varying power re­
quirements of the plug-in units.
Safety Information
This instruction manual contains warning information
which the user must follow to ensure safe operation of the
instrument. Warning information is intended to protect the
operator and Caution information is intended to protect
the instrument.
To prevent damage to the instrument, always check
the line-voltage information recorded on the rear
panel before applying power to the instrument.
WARNIWG~|
This instrument is intended to be operated from a
single-phase earth-referenced power source having
one current-carrying conductor (the Neutral Con­
ductor) near earth potential. Operation from power
sources where both current-carrying conductors
are live with respect to earth (such as phase-to-
phase on a three-wire system) is not recommended,
since only the Line Conductor has over-current
(fuse) protection within the instrument.
This instrument has a three-wire power cord with a
polarized two-pole, three-terminal plug for connec­
tion to the power source and safety-earth. The
safety-earth terminal of the plug is directly con­
nected to the instrument frame. For electric-shock
protection, insert this plug only in a mating outlet
with a safety-earth contact.
Do not defeat the grounding connection. Any in­
terruption of the grounding connection can create
an electric-shock hazard. Before making external
connections to this instrument, always ground the
instrument first by connecting the power-cord to a
proper mating power outlet.
WARNING
I
High voltage is present inside the instrument. To
avoid electric-shock hazard, operating personnel
must not
remove the protective instrument covers.
Component replacement and internal adjustments
must be made by qualified service personnel only.
OPERATING TEMPERATURE
The instrument can be operated where the ambient air
temperature is between 0Q C and +50° C. The instrument
can be stored in ambient temperature between — 40° C and
+70° C. After storage at a temperature beyond the
operating limits, allow the chassis temperature to come
within the operating limits before power is applied.
