First, use the time-per-division knob to scrunch the waveform horizontally so that four or five full cycles appear on the display. Second, use the volts-per-division knob in combination with the vertical-positioning knob to stretch the waveform as much as possible vertically, while keeping the entire waveform within the display area, and positioning the negative peaks so they rest on the second lowest horizontal grid line. Third, use the horizontal-positioning knob to position a positive peak right on the central vertical grid line. Your display will look similar to Figure 6. Fourth, measure and record the number of divisions along the central vertical axis from the next-to-lowest horizontal grid line (where the negative peaks sit) to the positive peak. Try to obtain one-tenth of a division precision. Fifth, record the volts-per-division setting of the oscilloscope. Sixth, calculate the peak-to-peak amplitude of the signal is volts
