Display Screen Chapter 6
The left side of the screen contains the list of voltage sags, which are identified by
the following fields:
Use the up/down arrows to navigate through the list. The currently selected
voltage sag will appear in the detail pane on the right side of the screen.
Voltage Sag Detail
The right-side of the Voltage Sag screen shows detailed information about the
selected voltage sag (See
