3.7.3 Captured inrush
This function becomes active after logging is completed
. The recorded signal trace
can be scrolled through and reviewed with a cursor. Data are displayed in graphical
(logger histogram) and in numeric (interval data) form.
The following values can be displayed in the data fields:
- Minimum, maximum and average data of the interval selected with the cursor,
- Time relative to the trigger-event time.
Complete trace of selected signal can be viewed on the histogram. The cursor is
positioned to the selected interval and can be scrolled over all intervals. All results are
saved to the instrument memory. Signals are auto scaled.
