Why do Waveform Captures on the ION7350 show 0 V for only the B phase

Issue
When a waveform capture is created on an ION7350 monitoring a 3-phase system, there is a reading of 0 V on the B-phase waveform.

Product Line
ION7350

Environment
Power Monitoring Expert 7.2.x, 8.0, 9.0, 2020, 2021, 2022, 2023
Struxureware Power Monitoring Expert 7.0.x
ION Enterprise 5.x, 6.0.x

Cause
The ION7350 is configured with a Delta Volts Mode. While Delta Volts Mode will calculate the B phase voltage for monitoring, it will not use calculated values for the waveform capture.

Resolution
If the ION7350 is connected to a 4-wire Wye circuit, the the resolution is to rewire the ION7350 for a 4-wire circuit and reconfigure the meter to be a Wye Volts Mode.
However, if the ION7350 is wired to a 3-Wire Delta circuit, the device must remain configured as Delta Volts Mode and B phase voltage will remain unavailable.
