Phase Powers Readings

In addition to three-phase power, the RDM shows per-phase power readings in
configurations with a neutral. By default, they are disabled. See

Configuring the RDM

on how to enable per-phase power readings in your RDM.

Fundamental Harmonic Readings

The RDM shows volts, currents, total power factor and active power for the
fundamental harmonic if they are enabled through the Display Setup Menu (see

Configuring the RDM

).

Min/Max and Max. Demand Display

Press the MIN/MAX key. The MIN/MAX LED is illuminated. Use the UP/DOWN arrow
keys to scroll through Min/Max and Max. Demand measurements.

The following table shows Min/Max display pages. Note that volts readings are

phase-to-neutral in 4LN3 and 3LN3 wiring modes, and phase-to-phase in all other
modes.
