Front Panel LEDs
The front panel LEDs are as follows:
The green operation LED (top) should always be on when the meter is in
service. Contact Technical Services if this is not the case.
The green LED in the middle is factory configured to be a Wh (del+rec) pulser.
During the course of normal operation, this LED should blink intermittently as
the meter measures power system energy.
The red LED (bottom) on the front panel of the meter is provided for custom
applications. Possible applications include sag/swell alarming, setpoint
annunciation, and tariff notification. Like all the other outputs on the meter, this
port can be controlled by a Digital Output, Pulser, or Calibration Pulser module.
Backlight Operation and Display Contrast
The front panel display is factory configured to dim five minutes after the last
button press.If the front panel is dimmed, press any button to return the LCD to
full brightness. The front panel display is adjusted at the factory to the optimal
contrast level. If the contrast needs adjusting or want to change the backlight time-
out period, you can do so from the Display Setup menu (see page 41).
Status Bar
The Status Bar of the meter is located along the top of all display screens. When in
data display mode, the Status Bar shows: the date in MM/DD/YYYY format
(configurable), the current local time in 24 hour format, and the data display screen
title.
Display Screen Types
The meter’s front panel displays measurements, configurable settings, and current
configuration data in various forms. These data display screens are described
below. Configuration (Setup menu) displays are described in the chapter "Default
Functionality."
Numeric Displays
Numeric displays can show multiple parameters at a time: two, three, three with a
timestamp, four, eight, ten (shown), or twenty. When displaying numeric values
for current and power quantities, the front panel shows resolution to three decimal
places by default. All other values are displayed to two decimals of accuracy. If
you want to see finer resolutions, use Vista software to display the data.
If the front panel is unable to read a numeric value, or if the value is not available,
it displays a dash (—).
