3. Set up the oscilloscope: Push the front-panel AUTOSET button.
4. Set the time base: Use the front-panel HORIZONTAL SCALE knob to set
the horizontal scale to 200 s/div. The time-base readout is displayed at the
bottom of the graticule (see Figure 1--6).
5. Verify that the time base operates: Confirm the following statements:
H One period of the square-wave probe-compensation signal is about five
horizontal divisions on the screen for the 200 s/div horizontal scale
setting.
H Rotating the SCALE knob clockwise expands the waveform (more
horizontal divisions per waveform period), counterclockwise rotation
contracts it, and returning to 200 s/div returns the period to about five
divisions.
H The HORIZONTAL POSITION knob positions the signal left and right
on the screen when rotated.
