The number of recorded events is indicated on the upper
part of the screen.
Events recorded in internal memory are represented by
co
lored blocks.
A total of 50 blocks can be colored, beginning at the bot-
tom left and ending at the top right.

Indicates that 46 events have been recorded
Although up to 50 inrush events can be detected, inrush current fluctua-
tion data can be recorded (and a graph displayed) for only one INRUSH
ev
ent (indicated by *I in the Event List).
Event Monitor
The number of occurrences of each event type is displayed. Event types that have not occurred are
indicated by "0". When an event occurs, the number of occurrences is displayed in red.

Event Type
Tran. Transient Overvoltage
Swell Voltage Swell*
Dip Voltage Dip*
Inter. Interruption*
Ext. External (Start, Stop, Timer, Manual or Inrush current)
* Voltage swell, voltage dip and interruption events have EVENT IN (onset) and EVENT OUT (re-
covery) occurrences. Therefore, most such events occur in pairs (onset and recovery), and the
mo
nitored values are usually multiples of two.
