(2) CURSOR measurement
1) Make the GND fuminescent line be displayed by means
of ordinary procedures 1) and 2). ©
2) Set the cursor mode to 4 V1 or
AV2 in accordance with
the channel to be used.
3) Adjust the 4 REF cursor (reference line) to the GND lu-
minescent line.
4) Set the AC-GND-DC switch to DC.
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 PC-33 is used, measured value in-
cluding the attenuation ratio is displayed. If a probe in-
compatible with the readout function is used, measured
value is multiplied by the attenuation ratio.
Lowering of the A cursor below the A REF cursor indi-
,
cates negative voltage, displaying ''—''.

2. MEASUREMENT OF THE VOLTAGE BETWEEN
TWO POINTS ON A WAVEFORM
(1) 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. Set the AC-GND-
DC to AC, adjusting VOLTS/DIV and SWEEP TIME/DIV
for a normal display. Set the VARIABLE control to CAL
position.
2. Using the * POSITION control, adjust the waveform po-
sition such that one of the two points falls on
a CRT
graduation line and that the other is visible on the dis-
play screen.
3. Using the <
POSITION control, adjust the second point
to coincide with the center vertical! graduation line.
4. Measure the vertical distance between the two points
and multiply this by the setting of the VOLTS/DIV control.
When a 10:1 probe is used, further multiply the value
by 10.

[EXAMPLE]
For the example, the two points are separated by 4.5
divisions vertically. Set the VOLTS/DtV setting be
0.2 V/div and the probe attenuation be 10:1. (See Fig.
19)
Substituting the given value:
Voltage between two points=4.5 (div) x 0.2(Vidiv) x 10=9.0V
(2) Cursor measurement
(CS-5130 only)
1) Make waveform

be displayed on the
screen in ordinary procedure
1).
2) Set the cursor mode to 4V1 or AV2 in accordance with
the channel to be used.
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 screen.
