First, the trigger T is aligned
to the center graticule line.
Second, the horizontal
modes are set.
Third, the horizontal scale for
D time base is set and a
10 ms delay is entered.
Fourth, the waveforms rising edge is
checked to be within ±2.5 horizontal
divisions of the center horizontal
graticule line.
