Bit mapped per trigger
events. 1 indicates a

and that the change to
the present state
caused the event.
0 if cycle was not cap-

Always 0
Tag of the last sample
in the event cycle
For events ending a
surge or sag episode
(e.g. return to nor-
mal), RMS of the
channel is the worst
excursion (highest
surge, lowest sag) for
the episode. 0 for
other channels. Same
