42 User Manual
The readings at the current position are displayed on the meters and
secondary readings panels. When displaying live data, these are cur-
rent readings as they are received from the Sentinel; at other positions
in the timeline, saved readings are displayed. When dragging the cur-
rent position, the readings update as the cursor moves.
The current position cursor always stays within the visible portion of
the timeline display. When repositioning of the display would move
the cursor out of view, it sticks at the end of the displayed range – that
is, it moves to the position within the display area that is closest to its
prior position. This can have the side-effect of pausing the display. (To
resume showing live readings, you can press the Skip Forward button
to advance the position to the current time.)
Segment bounds cursor pairs
Segment bound cursor pairs indicate the bounds of programming seg-
ments. Each pair corresponds to an entry in the segment table. Both
bounds cursors display the segment number, which also appears on
the segment table entry.
Bounds cursor pairs are created and deleted as segments are added
and removed from the segment table, using the segment add/remove
buttons provided by the segment table (p. 45). You can also remove
a pair (and its associated segment) by dragging either cursor off the
timeline vertically.
Dragging the left bound of a pair moves both cursors, maintaining their
separation. Dragging the right bound does not move the left. In other
words, you position a segment by dragging its left bound, and change
its duration by dragging its right bound.
Bounds cursors move independently when dragged, except that nei-
ther cursor can be dragged past the other, and instead pulls the other
cursor along with it. The cursors are adjacent when a new segment is
created – you can separate them by dragging one back and forth.
Dragging when playing logged readings changes to paused state.
Dragging while playing live readings does not change state, and live
play resumes when dragging stops.
