Reviewing Power Quality Event Data
The 933A treats Power Quality event records in much the same way as
User event records, only it follows the rules of IEC 61000-4-30, paragraph
5.4, for Voltage Dips and Swells. When you select a specific event record
(using either the ENTER or numeric keys) it will reveal the waveform at
the time of the event.
1. Press the REVIEW key and select the SHOW PWR QUAL soft key.
A list of any power-quality event records will appear in the display,
if the 933A has captured any (see Figure 5.8, left screen).
2. Press the ENTER key, or any numeric key corresponding to the
record number in the list, to view the waveform record at the time
of the event (see Figure 5.8, right screen).
3. To access other power-quality event records, press REVIEW
>
SHOW PWR QUAL as in step 1.
Figure 5.8: Selecting and Viewing Power Quality Records
Notice that each data record provides a record number, trigger number,
date and time of event, max and min values attained while the trigger
was active.
Max and Min values are only produced after trigger becomes
inactive
.
