6.3.2.3 Curve recording, return point
The DIGIFORCE
®
9311 divides a recorded measurement curve into two curve segments: a forward
segment and a return segment.
You can use the "Record curve to" parameter to select between "Complete curve" and "Return point".
Select "Complete curve" to display and evaluate the forward and return segments of the measurement
curve. "Return point" means that the DIGIFORCE
®
9311 displays and evaluates only the forward segment
up to the defined return point.
You use the "Return point" parameter to specify which point in the curve is the last value pair of the
forward curve, i.e. is the return point. You can choose from "Xmin", "Xmax", "Ymin" and "Ymax". When
opting to record the "Complete curve", this return point is marked as a green diamond in the
"M1 Graphical meas. curve" displayed in the DIGIFORCE
®
9311 measurement mode.
Parameters in the "Measurement mode, Return point" menu (M19)
Return point Xmin, Xmax, Ymin, Ymax The DIGIFORCE
®
9311 uses the specified
value to determine the last measurement point
of the forward curve, i.e. the return point.
Record curve to Return point / Complete curve Return point :
The DIGIFORCE
®
9311 displays and evaluates
just the forward curve.
Complete curve
:
The DIGIFORCE
®
9311 displays and evaluates
the entire curve (forward and return segments).
