Events Table
Figure 16-2. Events Table
The events table shows the events that occurred during the measurement with date/time
of start, phase, and duration. The amount of information in the table can be selected with
the Function keys F2 and F3:
• Selected gives a table with events as selected: Only V rms, Harmonics, Flicker,
Dips/Interruptions/Rapid Voltage Changes/Swells, or Unbalance/Frequency.
All gives a table with all events. This allows you to see cause and effect of events.
• Normal lists the major event characteristics: start date/time, duration, event type, and
magnitude.
Detail gives information on threshold crossings for each phase of an event.
The following Abbreviations and Symbols are used in the tables:
Abbreviation Meaning Symbol Meaning
CHG Rapid Voltage Change High value of 100 % limit
has been violated
DIP Voltage Dip Low value of 100 % limit
has been violated
INT Voltage Interruption High value of x % limit
has been violated
SWL Voltage Swell Low value of x % limit
has been violated
Hx Number of the harmonic
that violated its limits Unbalance event
