Sag/swell overview
Your meter monitors your power system’s voltage and current for sags and swells
(INCITS (CBEMA) Type 2 and Type 3 disturbances).
When sag/swell limits are defined and alarming is enabled, the meter reports the
disturbance’s magnitude and duration, and logs data and waveform records
associated with the disturbance.

Configuring Sag/Swell logging using ION Setup
Use ION Setup to configure your meter to log data and waveform records related
to sag/swell events, and to export the waveform data to COMTRADE files.
NOTE: There are 2 data recorders for logging sag/swell related data: Sag/
Swell Log (Data Recorder #5) records data for plotting the ITI(CBEMA) curve,
and Sg/Sw HS Log (Data Recorder #6) records voltage and current data from
the High-Speed Power Meter module.
To set up the Sag/Swell Log, Sag/Swell Burst Log, Sag/Swell Waveform Log and
Sag/Swell COMTRADE files:
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
3. Navigate to Power Quality > Sag/Swell Logging .
4. Select the data log and click Edit . Enter the meter password if prompted.
The Sag/Swell Logging Wizard appears.
5. The Device setting verification screen displays results of the meter
configuration check for potential errors related to sag/swell monitoring and
reporting. Click
Fix to view details, or click Next to ignore the results and
proceed to the next screen.
6. The Disturbance Logging Setup screen displays the Log Depth setting for
Sag/Swell Log (Data Recorder #5). You can change the maximum number of
