Measurement
Voltage
This screen shows the phase-neutral voltage values for each phase. You can see Min Voltage
(Phase-Neutral) and Max Voltage (Phase-Neutral) values by pressing the OK button. Depending on
the connection type in the Phase-Neutral voltage (3P3W, 3P3W balance and Aron), this screen will
not be displayed.
This screen shows the phase-phase voltage values for each phase. You can see Min Voltage (PhasePhase) and Max Voltage (Phase-Phase) values by pressing the OK button.
