• The demand screen displays demand values for current, real, and reactive power. The
peak value for current demand is recorded here and can be reset from this screen.
• The energy screen displays and allows the user to reset four quadrant energy values.
• The phasor screen graphically displays the phasor components of the system voltage
(phase-neutral) and current.
• The sequence screen graphically displays the sequence components of the system
voltage and currents.
The user can access the mimic diagram and dedicated control pushbuttons from the
