inaccuracies introduced by the user's potential and
current transformers. Accuracy calculated at 1second
average.
 Specifications assume: voltage and current waveforms
with THD  5% for kvar, kVA and PF, and reference
operating temperature 20  C - 26  C.
 Measurement error is typically less than the maximum
error indicated.
