Note: This document is applicable for:
All models - v03.02.12.
EM6400, EM6459, EM 6434 – v03.02.02.
EM 6436, EM 6433 – v03.02.11.
The EM 6400 provides all single phase (per-phase) Real, Apparent, Reactive Power and
Power Factor values. Positive (Inductive) and Negative (Capacitive) Reactive Energy is
separately accumulated for Lead / Lag analysis. OLD Energy values for VAh, Wh, VARh, -
VARh is available.
