3.SEC/DIV Knob: Used to change the horizontal time scale so as to magnify or compress the
waveform horizontally. If the waveform acquisition is stopped (by using the RUN/STOP or SINGLE
SEQ button), the SEC/DIV control will expand or compress the waveform. In dual-window mode,
push this knob to select major or minor window. When the major window is selected, this knob
provides the same functions as it provides in single-mode window. When the minor window is
selected, turn this knob to scale the waveform whose magnification is up to 1000.
