Volt-Meter Screen
From the Volt-Meter screen, you can select the following items:
Output Voltage Displays each phase-to-phase output voltage (e.g., L1-2 for phase L1 to
phase L2) and each phase-to-neutral output voltage (e.g., L1 for phase L1
to neutral).
Input Voltage Displays each phase-to-phase input voltage (e.g., L1-2 for phase L1 to L2),
or, if your service transformer is a Wye transformer, each phase-to-neutral
input voltage (e.g., L1 for phase L1 to neutral).
