2.2 User Characteristics

Measurement data from one measurement interval is short-lived and does not persist longer than one measurement interval. At the end of a measurement interval, the user is notified by a software interrupt. At this point, all relevant quantities must be read before the next measurement period ends.

There are two primary types of measurement intervals: the integration period, which can be configured through the N_MAX control register, and the line cycle.

Measurement data associated with the integration period includes all registers related to Accumulated Output Quantities and Harmonic Analysis Output Quantities.

Measurement data associated with the line cycle includes all registers related to Per-Cycle Accumulated Output Quantities.
