The screen divides
in
half. The top half displays the main sweep, and
the bottom half displays an expanded portion of the

expanded portion of the main sweep is called the delayed sweep. The
top half also has two solid vertical lines called markers. These markers
show what portion of the main sweep is expanded in the lower half.
The size and position of the delayed sweep are controlled by the
Time/Div and Delay knobs. The Time/Div next to
the~
symbol is the
delayed sweep sec/div. The delay value is displayed
for
a short time at
the bottom of the display.
