12) CURSOR measurement
1) Make the GND luminescent line be displayed by means
of ordinary procedures 1) and 2 ) .
2) Set the cursor mode to A V 1 or A V 2 in accordance with
the channel to be u s e d .
3) Adjust the A R E F cursor (reference line) to the GND lu-
minescent line.
4) S e t the A C - G N D - D C s w i t c h to D C .
5) Adjust the A cursor to a point to be measured.
6) Measured value is displayed in the upper right part on
the screen.
If the attached probe P C - 3 3 is used, measured value in-
cluding the attenuation ratio is displayed. If a probe in-
compatible w i t h the readout function is u s e d , measured
value is multiplied by the attenuation ratio.
Lowering of the A cursor below the A R E F cursor indi-
cates negative voltage, displaying " - " .

2. MEASUREMENT OF THE VOLTAGE BETWEEN
TWO POINTS ON A WAVEFORM
ID Ordinary measurement
This technique can be used to measure peak-to-peak
voltages.
1 . Apply the signal to be measured to the INPUT jack. Set
the vertical MODE to the channel to be used. Set the ver-
tical MODE to the channel to be used. S e t the A C - G N D -
DC to A C , adjusting V O L T S / D I V and S W E E P T I M E / D I V
for a normal display. S e t the V A R I A B L E control to C A L
position.
2 . Using the T POSITION control, adjust the waveform po-
sition s u c h that one of the t w o points falls on a C R T
graduation line and that the other is visible on the dis-
play s c r e e n .
3 . Using the
POSITION control, adjust the second point
to coincide w i t h the center vertical graduation line.
4 . Measure the vertical distance between the t w o points
and multiply this by the setting of the V O L T S / D I V control.
When a 1 0 : 1 probe is u s e d , further multiply the value
by 1 0 .

[EXAMPLE]
For the example, the t w o points are separated by 4 . 5
divisions vertically. Set the V O L T S / D I V setting be
0 . 2 V/div and the probe attenuation be 1 0 : 1 . (See Fig.
19)
Substituting the given value:
Voltage between two points=4.5 (div) x 0.2(V/div) x 10=9.0V
| 2 ! Cursor measurement (CS-5130 only)
1) Make w a v e f o r m to be observed be displayed on the
screen in ordinary procedure 1).
2) Set the cursor mode to A V 1 or A V 2 in accordance with
the channel to be u s e d .
3) Adjust the A REF cursor to a lower point to be measured,
and the A cursor to another point.
4) Measured value is displayed in the upper right part on
the s c r e e n .
