(1) Insert the supplied power cord to the power connec-
tor. Then, select the position of the power voltage se-
lector plug as indicated by the arrow marks.
(2) Turn POWER (15) clockwise. The power is turned to
ON and LED pilot lamp (14) lights.
(3) Horizontal axis will be displayed. When fly-back line
does not appear at the center of the screen, adjust
POSITION (1) and POSITION P U L L x 5 MAG (24).
Adjust brightness with INTENSITY (16). If fly-back
line is unclear, adjust FOCUS (19).
(4) The oscilloscope is now ready for measurement. For
measurement, proceed as follows:
Apply signal voltages to the Input terminals (3), (11).
Then turn VOLT/DIV (5) clockwise until the waveform
is correctly displayed on the scope. By setting MODE
(7) and SOU RCE (21) to CH1, the CH1 input signal to
the Input terminal (3) will appear. Similarly, by setting
MODE and SOURCE to CH2, then the input signal to
the CH2 terminal (11) will appear. When MODE (7) is
set to DUAL, two waveforms (CH1 and CH2) will ap-
pear on the scope. With SOU RCE (21) set to CH 1, the
CH 1 input signal from the Input terminal (3) is fed to
the synchro circuit where the CH1 signal is synchro-
nized. Similarly, when SOURCE is set to CH2, the
CH2 signal is synchronized. Use either method for
easier observation.
When MODE is set to ADD, the CH 1 signal is alge-
braicly added to the CH2 signal; and when it is set to
SUB, the CH2 signal in reverse polarity is added to the
CH 1 signal and the abgebraic difference between CH 1
and CH2 is displayed.
(5) When the signal voltage is more than 10 mV and
waveform fails to appear on the screen, the os-
cilloscope may be checked by feeding input from
CAL 1 Vp-p (27). Since calibration voltage is 1 Vp-p, the
waveform becomes 5div high at the 0.2V/div position,
tion.

By pushing LEVEL (23), the free-running auto function
is released. The waveform disappears when the knob
is turned clockwise, and appears again at the ap-
proximate mid position of it. Sync phase is also ad-
justable in this case. The waveform will again dis-
appear when the knob is turned counterclockwise
from the mid position.
(7) When DC component is measured, set AC-GND-DC to
DC position. If, in this case, the DC component con-
7
their functions (see page 4).
When starting this oscilloscope set initially, set the operating
controls as follows and the set may be turned on safely.
