Limit
Limit Line
Activates an adjustable horizontal line that is used
as a visual reference line.
The limit line, used for trace arithmetic, has
amplitude values that correspond to its vertical
position when compared to the reference level. The
value of the display limit line appears in both the
active function block and on the left side of the
display. The arrow keys, knob, or numeric keypad
may be used to adjust the displayed limit line.
Pressing any digit, 0 through 9, on the numeric
keypad brings up the selected terminator menu. To
deactivate the display line, press Display Line (Off).
