These lamps light up when the following wiring modes are selected:
1P2W×2 1-phase/2-wire × 2 circuits (CH1 and CH2 are 1-phase/2-wire.)
1P3W 1-phase/3-wire
3P3W
3-phase/3-wire, active power measurement using the two-pow-
er-meter method
3P3W2M
3-phase/3-wire, active power measurement using the two-pow-
er-meter method (Displays line voltage and phase current, which
are not measured, using vector calculations.)
1P2W×3
1-phase/2-wire × 3 circuits (CH1, CH2, and CH3 are 1-phase/2-
wire)
1P3W&1P2W
1-phase/3-wire & 1-phase/2-wire (CH1 and CH2 are 1-phase/3-
wire, Active power is measured by 2-power measurement meth-
od, and CH3 is 1-phase/2-wire.)
3P3W&1P2W
3-phase/3-wire & 1-phase/2-wire (CH1 and CH2 are 3-phase/3-
wire, and CH3 is 1-phase/2-wire.)
3P3W2M
3-phase/3-wire, active power measurement using the two-pow-
er-meter method (Displays wire voltage and phase current,
which are not measured, using vector calculations.)
3V3A
3-phase/3-wire, active power measurement using the two-pow-
er-meter method (Actually measures and displays all wire voltag-
es and phase currents.)
3P3W3M
3-phase/3-wire (Converts and displays wire voltages and phase
voltages using vector calculations with 3V3A wiring.)
3P4W 3-phase/4-wire
