5. Count the

number

divisions

both the top and bottom

the

waveform and multiply the resultant number by the value

the

VOLTS

/DIV

switch. thus result ing in the peak-to-peak voltage.

For

examp

le, if the value of the VOLTS

IV switch was set to 2V when

the wavef

orm

same

as that shown in Fig. 2-16 had been measured, it

would in fact be 8.0

-p,

(4.0divX 2.0V= 8.0V)

6. If the

ind

ication of the vertical magnification is X5, divide the

mea

sur

ed value by 5.

However, if the probe is 10:1, multiply the voltage by 10.

When mea

surin

g a sine wave below 100Hz or a square wave below 1KHz,

set the AC-

,GND switches to DC.

lIT

ION :

ere the wav

orm

is lo

aded

with the high potential DC

voltage, the above mea

surement

is difficult.

At this time,

perf

orm

the measurement with setting the

AC-DC,GND

switches to DC.

(Wh en the mea

For

any

instrument

equipped

with readout function, movin

cursor to the top and bottom of wavef

displays the

potential difference V on the screen.

eous Voltage

Measurement

1. Set up the vertical m

ode

switch of the oscilloscope in the same

manner

that

set out in 2-2.

BASIC

MEASURE

MENT

above.

2. Adjust the

TlM

E/DIV switch [

221

or [23I so as to become a complete

waveform' and set the VOLTS/DIY switch to produce 4 to

6 divisions

(See Fig.

2-(7) .

3. Set the AC

-DC,GND

switch

or (12) to GND.

4. Turn the Vertical POS ITION control [1

or [18] and make it align

with eit

her

the lowest central horizontal graticule line (in case

positive (%) signal) or the uppermost

one

(when the signal is

ncgativef-) ).

NOTE

: The vertical PO

SITION

cont

rols must not be touched until the

measurement is completed.
