6.3.2.6.2 Measurement curve reference
The DIGIFORCE
®
9311 provides the following X-references for the measurement curve:
Reference Absolute
The DIGIFORCE
®
9311 references the
measurement curve to the absolute zero
point of the measurement system on the X-
channel (e.g. displacement sensor).
Final force
The last measurement point of the forward
measurement curve is the reference point
(X = 0). For a forward and return curve, the
return point is the reference.
Y reference line overrun,
Y reference line underrun
The reference point is where the curve
crosses above or below the set Y-level
(Y reference line).
<value input> Enter the value for the Y-level.
Y trigger overrun,
Y trigger underrun
The reference point is where the curve
crosses above or below the set Y-level
(Y trigger).
Note: For the "Crossing trigger threshold"
reference, the DIGIFORCE
®
9311
does not start saving curve data
until the trigger event has occurred.
The measurement, however, must
be started before the trigger event.
<value input> Enter the value.
