NOTE
Instantaneous DC Voltage
To measure the dc level at a given point on a waveform,
use the following procedure:
1.
Preset instrument controls and obtain a Normal
Sweep Display.
2. Apply the signal to either vertical-channel input
connector and set the VE R TIC A L MODE switch to display
the channel used.
3. Verify that the VO LTS /D IV VAR control is in the
calibrated detent and set the AC-GND-DC switch to GND.
4.
Vertically position the baseline trace to the center
horizontal graticule line.
5.
Set the AC-GND-DC switch to DC. If the waveform
moves above the centerline o f the crt, the voltage is
positive, if the waveform moves below the centerline o f the
crt, the voltage is negative.
I f using Channel 2, ensure that the CH 2 IN V E R T
switch is in its noninverting mode (push b u tto n out).
6.
Set the AC-GND-DC switch to GND and position the
baseline trace to a convenient reference line, using the
Vertical POSITION control. For example, if the voltage to
be measured is positive, position the baseline trace to the
bottom graticule line. If a negative voltage is to be
measured, position the baseline trace to the to p graticule
line. Do not move the Vertical POSITION control after
this reference line has been established. The ground refer
ence line can be checked at any later time by switching the
AC-GND-DC switch to GND.
7. Set the AC-GND-DC switch to DC.
8.
If the voltage-level measurement is to be made w ith
respect to a voltage level other than ground, apply the
reference voltage to the unused vertical-channel input
connector. Then position its trace to the reference line.
9.
Adjust the A TRIGGER LEVEL control to obtain
a stable display.
