ION Setup User Guide Using the Setup Assistant
Phasor Viewer
From the Verification screen, you can check the wiring on some ION meters with
the real-time Phasor Viewer. The Phasor Viewer provides detailed harmonics
calculations for a voltage or current input on a meter. This information is valuable
for power quality analysis, selecting properly rated transformers, and fault
detection. For more information on meter wiring, refer to the technical note
Troubleshooting Meter Wiring.
NOTE
The Phasor Viewer is set up by default to display correctly for the meter installer. Users can change the
display to rotate clockwise or counterclockwise using the Phasor Rotation option in the View tab of the
Options dialog box (see “View tab” on page 34). Users who are not installing a meter should utilize the
Phasor Viewer’s Delta Vector Display mode (see ION Reference for details).
To access the Phasor Viewer:
1. Connect to your meter in ION Setup.
2. Open the Setup Assistant, go to the Verification screen and click the Wiring tab.
3. Select Phasor Viewer, then click Confirm.
The Phasor Viewer appears, containing both voltage and current phasors on the
Combined and Side by Side tabs. The combined view also contains power
readings.
