OSCILLOSCOPE OPERATION
Refer to the previous section " C o n t r o l s on P a n e l s " . Before
operating the oscilloscope, set the s w i t c h e s and controls
as follows:

1 . Connect the supplied power cord to the power con-
necter. T h e oscilloscope is factory adjusted to operate
on A C 2 4 0 V .
2. Turn the P O W E R s w i t c h (1) to ON and the P O W E R lamp
(2) will light. T h e n horizontal trace will appear. If
horizontal trace does not appear at the center of the
screen, adjust the
T
POSITION ( 1 0 ) .
3 . Adjust the intensity by the I N T E N S I T Y ( 3 ) . If the trace is
unclear, adjust the F O C U S ( 5 ) .
4 . If the trace is inclined, adjust the T R A C E R O T A T I O N ( 4 ) .
5. Set the A C - G N D - D C ( 1 3 ) to A C or D C position and app-
ly input signal to the INPUT ( 1 4 ) . Turn the V O L T S / D I V
(8) clockwise to obtain optimum w a v e f o r m .
6. If the w a v e f o r m is running and not triggered, turn the
L E V E L ( 2 7 ) . By pushing the L E V E L knob, the auto func-
tion is released. T h e w a v e f o r m disappears when the
knob is turned clockwise or counterclockwise and ap-
pears again at the approximate midposition of it. Turn
the knob until optimum triggering level is obtained.
7. W h e n the signal voltage is more than 0 . 0 1 V and
w a v e f o r m does not appear on the screen, the
oscilloscope may be checked by feeding input from the
C A L (6) terminal. Since the calibration voltage is 1 Vp-
p, the w a v e f o r m becomes 5 div at the 0 . 2 V position of
the V O L T S / D I V .
8. In measuring D C component, set the A C - G N D - D C ( 1 3 )
to D C . If it contains positive ( + } potential, the
w a v e f o r m moves upward. If negative ( —) potential is
contained, the w a v e f o r m moves downward. T h e zero
potential can be checked at the GND position.

Operation
1 . Operate the oscilloscope and display a triggered signal
on the screen.
2. Depress the W R I T E S T A R T ( 1 6 ) and the W R I T E ( 1 8 )
lamp will light.
3 . W h e n the W R I T E lamp goes off, the R E A D (19) lamp
begins to flicker.
4 . Set the D I S P L A Y MODE ( 1 2 ) to D U A L or M E M O R Y , and
memory w a v e f o r m will be displayed. In the D U A L mode,
the real time w a v e f o r m overlaps w i t h the memory
w a v e f o r m . B y adjusting the
T
P O S I T I O N ( 1 0 ) or
M E M O R Y POSITION ( 1 1 ) , both w a v e f o r m s can be
observed.
5. W h e n observing memory w a v e f o r m , it is not necessary
to adjust the V O L T S / D I V (8) and S W E E P T I M E / D I V
( 2 1 ) . T h e V O L T S / D I V does not change the amplitude of
the memory w a v e f o r m . T h e S W E E P T I M E / D I V changes
only the readout speed; the memory w a v e f o r m remains
unchanged on the screen.
[B] Automatic write-in, read-out Operation
Pull out the D I S P L A Y T I M E ( 3 1 ) forward you and set this
control at about 9 o'clock position in F R E E RUN state.
Refer to F R E E RUN function on page 1 1 .
