(2) 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! or A V2 in accordance with
the channel to be used.
3) Adjust the A 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 posterior to A V1 or A V2.
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
vertical MODE to the channel to be used. Set the AC-
GND-DC to A C , adjusting VOLTS/DIV and SWEEP
TIME/DIV for a normal display. Set the VARIABLE con-
trol to CAL position.
2. Using the • POSITION control, adjust the waveform
position such that one of the two points falls on a CRT
graduation line and that the other is visible on the
display 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 con-
trol.
When a 10:1 probe is used, further multiply the value by
10.

(2) With direct measurement
Voltage between 2 points = Vertical distance (div) x 2
points.

[EXAMPLE]
For the example, the two points are separated by 4.5 divi-
sions vertically. Set the VOLTS/DIV setting be 0.2 V/div
and the probe attenuation be 1 0 : 1 . (See Fig. 33)
Substituting the given value:
Voltage between two points = 4.5 (div) x 0.2(V/div) x 10 = 9.0V
(2) Cursor measurement
1) Make waveform to be observed be displayed on the
screen in ordinary procedure 1).
2) Set the cursor mode to A V1 or A V2 in accor-
dance 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 posterior to A V1 or A V2.
