Kt. One complete “revolution” represents ten state changes, which represent Kh
watt-hours or var-hours. The meter illuminates the segments as follows:

If the W h direction is delivered (or the VArh direction is lagging), the states change
in increasing order with respect to the above illustration. If the W h direction is
received (or the VArh direction is leading), the states change in decreasing order.
Note: If the calculated phasor VAh is below the programmed creep threshold, the
meter will turn off the W h and VArh direction arrows.
9. These characters display the programmed metering quantities. There are three
possible decimal point positions located between the four rightmost digits.
3.2.1 Display Examples
The following figures show examples of WiMAX SmartMeter displays.
3.2.1.1 kWh Display
Figure 3-3: kWh Display
Figure 3-3 shows the following conditions:
1. The Display Label is “01”.
2. Six-digit display of energy (kW h).
3. Phase A present and voltage exceeds the low voltage threshold.
4. End-of-demand-interval indication. This indicator is lit at the end of each demand
subinterval .
