EXT. BLANKING
This is a terminal for applying a blanking
signal from an external source.
The trace dis
played on the screen may be intensity - modu
lated where pulse signal or time-scale marks
are required.
5V AC signal applied at the con
nector on the rear of the oscilloscope will pro
vide alternate brightness and blanking of the
trace.
Positive voltage input decreases bright
ness .
Power Supply Cord Connecting Terminal
FUSE
The fuse is released when the cap is rotated
counterclockwise.
FUSE:
lA 6.350
31.8 (mm)
Caution - Replace only with same type and rating
fuse.
CHI OUTPUT
Output connector providing a sample of the
signal applied to the vertieal input connector.
This connector is used for driving a frequency
counter or other instrument.
Precautions
Power Source Voltage
Apply a power source voltage that is within +10%
of the rated values as given in the table below.
Operation with a voltage less than 10% of rated
value may result in improper performance and
a voltage more than 10% of the rated value may
damage power supply circuitry.

(3) Horizontal Trace Tilt
Horizontal trace, in some case, tilts due to
the earth's magnetism.
(4) Operation in a Powerful Magnetic Field
Operation in a powerful magnetic field will
cause distortion of waveforms or make traces
tilt excessively.
Special care should be exer
cised when operating the instrument close to
