To import a limit line file (*.limit) you can also use the Windows Explorer and simply double-click
the file or drag and drop the file into the NWA application. You have to switch on the limit check
separately. Use the paste marker list for convenient entry of
Start and Stop values.
Columns in the segment table
The table contains an automatically assigned current number for each segment plus the following
editable columns:
•
Type indicates whether the segment belongs to an Upper or a Lower limit line, or if the limit
check at the segment is switched Off. Switching off the limit check does not delete the segment
but changes its screen color.
•
Start Stimulus is the stimulus (x-axis) value of the first point of the segment (not necessarily
smaller than Stop Stimulus).
•
Stop Stimulus is the stimulus (x-axis) value of the last point of the segment (not necessarily
larger than Start Stimulus).
•
Start Response is the response (y-axis) value of the first point of the segment .
•
Stop Response is the response (y-axis) value of the last point of the segment .
The limit line segment is calculated as a straight line connecting the two points (<Start Stimulus>, <Start
Response>) and (<Stop Stimulus>, <Stop Response>); see Rules for Limit Line Definition .
