8-3 measuring Di rect Current (DC) Voltage
The oscilloscope's vertical amplification Is proven by a direct current amplifier circuit
characterized by excellent stabi1ity. By switching the AC-GND-DC control to the DC
setting, direct current voltage may be measured.
1) Apply the signal to the INPUT terminal. Use the VOLTS/DIV and SWEEP TIME/DIV controls
to display the waveform at an easy-to-see size. Adjust the TRIGGER LEVEL control as
necessary.
2) Set the T. MODE control to AUTO. Set the AC-GND-DC control to GND. The trace line is
displayed on the CRT. This trace 1ine represents the ground potential. Use the
^POSITION control to bring the trace 1ine in contact with one of the horizontal
graduation lines. It is normally lined up on the OX graduation line if the signal is
positive. Or, it is 1 ined up on the 100% 1ine if the signal is negative. Once
1ined up, the trace position becomes the reference potential, so do not touch the
^POSITION control during measurement processes.
3) Set the AC-GND-DC control to DC. The signal is displayed on the CRT with the direct
current components intact.
If either the VOLTS/DIV or reference potential setting is inappropriate, the waveform
may disappear from the display screen. Make sure the settings are correct.
4) Measure the potential in the equivalent procedure to measuring the voltage between two
points. The potential sign is plus if above the reference or minus if below the
reference.
