Ca pacitor between inp ut connector

and

vertical

amplifier interrup ts any DC component of the

signal.

Connects input connector

of

vertical

amp

lifier

to the ground, thus establishing

G

ND

as a

reference point.

By making

dir

ect

con

nection between input

connector and vertical amplifier,

input

signal

is directly connected to vertical amplifier.

As being the attenuator by each step selecting

vertical deflection sensitivity, measurement

of waveform is practicable regardless of

signal magnitude and those shall be used by

having t

hem

placed at the appropriate positi

on

so as to make waveform measurement easy.

As being the minute ad

justor

being used when

having vertical deflection sensitivity

continuously varied, if they

ar

e fully rotated

counterclockwise the attenuation ratio becomes

less

than

1/2.5 of

ind

icated value.

When

you

pull out the knob, vertical axis sensitivity

becomes x5 times.

At time time. the maximum sensitivity becomes

ImV

.

Being used for

mov

ing vertical axis waveform.

Clockwise rotation moves waveform up

and

counterclockwise rotation moves

it

down.

When pulled'

out, the signal applied to

CH2

appears inverted.

Being used for selecting the display m

od

e of

vertical axis.

Disp

ly the signal input to

CH

I

on

the

CRT.

Displays only the signal input to CH2

on

the

CRT.
