14.4.5   True Meter

 ·True Meter Mapping allows individual circuits/ 

channels to be grouped as one, two or three  
phase meters and read as a single meter meter 
with total readings for the meter.

 ·For example: if channels 1, 2, 3 are a three-phase 

circuit, you can now obtain readings for a single 
three-phase circuit rather than having to sum 
three independent channels.  

 ·True Meter Mapping will mathematically derive 

the neutral current on three phase circuits, elimi-
nating the need for a CT.
