NOTE #2:
Number of elements corresponds to the number of meter elements in series.

TRUE THREE PHASE METER TESTING (USING CUSTOMER LOAD)

% Registration =
Reference Standard pulses B+C+D * Reference Standard Pulse Constant
NOTE #3:
If testing 3-phase, then 3 reference standards must be connected into ports B, C and D. If testing
2-phase, then 2 reference standards must be connected to ports B and C, B and D or C and D. If
two or three current inputs on the reference standards are connected in series, then the reference
pulse constant must be adjusted by the number of current inputs in series. See NOTE#1 for standard
testing.
