Kh or Kh is referred to as the watt-hour constant and equals the number of watt-hours for one turn of a electromechanical meter, or one pulse period for electronic meters, like the WattNode® Pulse meter. For example, if the WattNode meter generates one pulse every 1.2 kilowatt hours, then Kh = 1200 watt-hours / pulse.
- You want 1000 pulses per kilowatt-hour. This equals one watt-hour per pulse.
- CT=100 (CT rated amps)
- Kh=1 (one pulse per watt-hour)

- You want 1 pulse per kilowatt-hour. This equals 1000 watt-hours per pulse.
- CT=400 (CT rated amps)
