Position the display approximately as shown in Fig .
29A. Use the
DELAY TIME POSITION control to move the

pOint to the fi rst pulse . 80th intensified zones
will move when the DELAY TIME POSITION control is
adjusted. Use the A TIME control to move the time-
measurement pOint to the second pulse .
Set
the HORIZ DISPLAY switch to 8 DLY'D . Slightly
readjust the A TIME control to superimpose the
waveforms (see Fig . 298) . The DELAY TIME POSITION
