lower horizontal cursor touches the bottom of
the signal peaks.
10. Click on the voltmeter icon. The
DVM
:
box at the bottom of the computer’s
display shows the actual AC signal
level.
Notes:
• You can also calculate the approximate volt-
age level by multiplying the approximate dis-
tance by the deflection factor.
• This technique can also be used to make
measurements between two other points on
the waveform.
• To accurately measure an AC peak-to-peak
voltage, you should have at least two com-
plete cycles of a waveform on the display.
