DISTURBANCE RECORDER
CHAPTER 10: DIGITAL FAULT RECORDER
When set to “Trigger/Re-Trigger” or “Re-Trigger Only”, the disturbance recorder will be
re-triggered if the signal is still asserted at the end of the trigger period. The resulting
record will contain fault data only. A re-trigger is re-generated at the end of a
disturbance record if the signal is still asserted and if the number of re-triggers is less
than the value specified by the
Maximum Re-Triggers
setting.
