Viewing waveforms on your meter's webpages
7EN05-0390-00
Use the waveform viewer on your meter's webpages to view the meter's
COMTRADE waveform files.
Before you can view waveforms on your meter's webpages, you need to make
sure your meter is configured to record waveforms by setting the nominal voltage.
1. Launch a browser and go to the IP address for your meter, entering valid login
credentials when requested.
2. Navigate to Monitoring > Waveforms.
A screen displays with accordion menus for all 3 COMTRADE modules
(regardless of whether or not that COMTRADE module is being created by
the meter). The waveform viewer for COMTRADE_1 is expanded.
By default, COMTRADE_1 displays the sag/swell waveform records.
COMTRADE_2 and COMTRADE_3 are used if you have configured
additional waveform recorders and connected them to COMTRADE modules.
3. Select the accordion menu for the COMTRADE records you want to view, for
example COMTRADE_2.
The waveform viewer for those COMTRADE records is displayed.
4. Select the file you want to view from the record dropdown.
The numbering starts at 0 (zero), which means you select cmt0_00004 to
view the fifth file for COMTRADE_1.
5. Click or tap an individual voltage or current channel in the legend to show or
hide it in the waveform viewer.
