Ease of Use—Power Xpert
Meter 4000/6000/8000 Graphic
Display (Option)
The Power Xpert Meter 4000/
6000/8000 display features
a large easy-to-read white
backlit graphic LCD. The
information presented by
the display is organized into
an information architecture
that is easy-to-navigate and
organized for simplicity.
Screen navigation is
accomplished using a
navigation control dial and
a “back” button. The user
simply twists the knob on
the navigation control dial
to move between menu
selections and drill down
links on the screen. When
the selection is highlighted,
pressing the dial makes the
selection. Information is
displayed from a single meter
or an RS-485 daisychain of
up to 16 meters. The display
features a rich set of screens
including real-time data, trend
plots, waveform views and an
ITIC Plot. The graphic display
allows basic device setup and
password protected resets.
An audible alarm is available
to annunciate alarm
conditions.
