System Architecture Meter Overview
2-12 Meter Overview TM-iX0A-0805
M (Mega) — This Annunciator illuminates when the value shown by the Data Display is one
million of a specified unit.
k (kilo) — This Annunciator illuminates when the value shown by the Data Display is one
thousand of a specified unit.
V (Volts), W (Watts) — The W consists of two V-shaped Annunciators. When one Annunciator
is illuminated, it appears as the letter V. When both Annunciators are illuminated, they appear as
the letter W. These Annunciators illuminate when the value shown by the Data Display is either
Volts or Watts.
A (Amperes), R (Reactive) — These Annunciators can be used in conjunction with the
V Annunciators. They illuminate when the value shown by the Data Display is as follows:
• VA = Voltamperes
• VAR - The product of the total Voltamperes and the sine of the angle between current and
voltage.
h (Energy) — This Annunciators illuminates when the Data Display is showing an integrated
quantity.
PF (Power Factor) — This Annunciator illuminates when the value in the Data Display shows a
power factor value. Power factor values are calculated based upon the integrated quantities the
meter is configured (either factory default or with the iConFig application) to accumulate.
DEL (Delivered), REC (Received) — These Annunciators illuminate when the value in the Data
Display shows the contents of the related Delivered or Received billing registers. These
Annunciators do not indicate whether the actual power flowing through the meter is delivered or
received.
A, B, C (Per Phase Quantity) — These Annunciators illuminate when the value in the Data
Display is for the detected phase. When all Annunciators are extinguished, the quantity is for all
three phases.
Displays and Indicators
ID Code Display — When configured, this three-digit identifying code is displayed
simultaneously with an item shown in the Data Display area. (typically, a unique code is
configured for each Data Display item).
120, 277, 240, 480 (Service Voltage Indicators) — The meter detects the nominal service voltage
during power up and illuminates the display of the detected voltage. If the nominal service
voltage cannot be determined (as a result of an incorrectly wired socket, for example), all Service
Voltage Indicators are illuminated.
Voltage Potential Indicators — Illuminate when voltage is present in those phases
Quadrant Indicators — Illuminate to show the direction of the power presently flowing
through the meter and whether the power factors are leading or lagging. The quadrants are
defined as follows:
• Quadrant 1 (lagging) – Wh and VARh delivered to the customer.
• Quadrant 2 (lagging) – Wh received from the customer and VARh delivered to the customer.
• Quadrant 3 (leading) – Wh and VARh received from the customer.
• Quadrant 4 (leading) – Wh delivered to the customer and VARh received from the customer.
