Sequence of Events Recording (SER)
Over 1,000 records are stored in nonvolatile memory (retrievable via BESTCOMSPlus®). The SER can
be triggered by: Input/Output status changes, system operating status changes, or alarm annunciations.
Data Logging (Oscillography)
Up to 6 variables can be logged. The sampling rate is 1,200 data points per log, up to 1,199 pre-trigger,
4 ms to 10 s intervals, (4.8 s to 12,000 s total log duration).
