Measuring
Direct
Current
(DC)
Voltage
The
oscilloscope's
vertical
amplification is provided by a direct current amplifier
circuit
characterized by excellent stability. By switching the
AC-GND-DC
control
to the DC setting direct current voltage can be measured.
1.
Apply
the signal to the
INPUT
terminal.
Work
the
VOLTS/DIV
and
SWEEP
TIME/DIV
controls to display the waveform at an easy to see
size.
Also
adjust the
LEVEL
control if necessary.
2.
Set
thejTRIGGERING|MODE
control to
AUTO,
and then set
AC-GND-DC
to
GND.
The trace
will
be displayed on the
CRT
screen.
This
trace
will
become
the ground potential.
Work
the ^
POSITION
control to bring the trace in
line
with
one of the horizontal graduation
lines.
Usually
signals
with
positive
potential are
lined
up at the 0 % graduation and signals of negative potential
at the 100 % graduation. Once
lined
up, the trace's position
will
become
the reference potential, so do not touch the ^
POSITION
control during the
measurement process.
3.
Set the
AC-GND-DC
control at
DC.
The signal
will
be displayed on the CRT
screen
with
the direct current component intact. If in this case either the
VOLTS/DIV
or reference potential setting is inappropriate, the waveform
may
disappear from the display screen. Make sure to check
these
settings.
4.
Measure the potential using the procedure for measuring the voltage between
two
points. The potential sign
will
be plus if above the reference and minus
if
below the reference.

5.
If
there
is only signal to be measured, apply it to CHI, and
work
the
CH2
v
POSITION
control so
that
CH2 displays the ground potential. If the
MaaUWfll
MODE
control is set at either
ALT
or
CHOP
after this adjustment
is
made, you
will
be certain of the ground potential
throughout
the proce-
dure. However, make certain
that
the ground potentials of both channels are
always
the same.
