Demand Metering
Demand is an electric power term that expresses the average energy usage over a period of time.
The power monitor may be configured to measure demand using a fixed demand period or a
sliding window. The demand period may be timed internally, synchronized to an external
demand end-of-interval contact connected to the S2 status input, or synchronized using
communication.
This function applies to catalog numbers 1408-EM2 and 1408-EM3.
