The oscilloscope automatically measures the rms voltage and displays the
result on the display.
The oscilloscope makes automatic measurements on the first pulse or period
in the display. If a cycle of the waveform cannot be found as shown in the
delayed window in figure 2-10, the measurement is made using the delayed
window as the cycle. Figure 2-10 shows how to use delayed sweep to isolate
a pulse for an rms measurement.
