5) Three controls need to be adjusted to give a satisfactory display: the Vertical Section

volts/div and position, and the Horizontal Section time/div. These controls can be

adjusted two ways: by YOU, or by the oscilloscope.

For now, let’s have the oscilloscope do the adjustment. Press the Autoscale hardkey, a

white button just above the Vertical Section. You should see a display very similar to the

one below with about 2_ cycles of the squarewave (although the corners may not look quite

so square as they do below).

Note that a softkey called Undo Autoscale has appeared at the lower left of the display.

This can be a very valuable and time-saving button to use, under certain circumstances. Try

“undoing autoscale” by pressing this softkey button. Then, press the Autoscale hardkey

again, and you should see about 2_ cycles of the squarewave.

The next step (number 6, Probe Compensation) is so important it has an entire

page devoted to it.
