- Section Start-End
(only when Change of Section is made by Setting)
Set the start point and end point of the selected section.
Setting range
(The range is the same for the start point and end point.)
Time or displacement (Front)
(0 to 2047
×
Measurement Length/2000)
* Setting the start point > the end point is unacceptable.
Displacement (Back)
(-2047 to 0
×
Measurement Length/2000)
Operation
* Setting the start point < the end point is unacceptable.

Sct. Start-End
If the setting of Detection Interval AB is too short,
fine changes in load are detected so that a correct
value may not be able to be held.
In this case, set Detection Interval B large as close
to the load change time as possible, and also set
Detection Load Difference large according to the
amount of change, by which an inflection point is
held in the correct position
.

・
If the section start point and end point of two sections are set identically
Front reference: The start point of the next section becomes valid.
Back reference: The end point of the previous section becomes valid.
Example) If the setting is the end point (section 1) = start point (section 2) = X
Front reference: The X point falls on section 2.
Back reference: The X point falls on section 1.
・
If the displacement pace is fast, sampling may not be performed in time and
no load may be held at the section start point. In that case, the load in time
for sampling near the section start point is held.
Also, when the section start point and end point are set identically, if the
displacement pace is fast, no load may be held. Set the section start point
and end point having a margin in consideration of the case where the
displacement pace is fast.
It is preferable to have a margin of the Measurement Length/2000
× 10 or
more.
