This event change continues until the voltage either returns back
into the nominal band, or moves past another trip point. Each
time the voltage moves past another trip point, the existing event
change ends, and a new event change is triggered. The trip
points can be visualized as a grid (every 6V in the above example)
from 0V to 150V (the maximum Eagle voltage), and any time the
line voltage crosses a grid line, an event change is triggered.

What is Recorded
When an event change is triggered, the trigger time is recorded,
with one cycle resolution. The RMS current, one cycle before the
trigger, is recorded. The direction of the voltage change, or slope,
is also recorded. This is displayed in ProVision or WinScan as a
minus for a sag and a plus for a swell. While the event is
occurring, the Eagle keeps track of the maximum and minimum
current and voltage values. When the event ends, the maximum
and minimum RMS voltage and currents are recorded, along with
the duration (in cycles). One cycle later, the RMS currents are
measured to record the currents after the event.
All voltage and current measurements are recorded for every
channel, regardless of which channel triggered the event. If a sag
