NOTES
1. Accuracy is expressed as ± (percentage of reading + percentage of full scale) ± 1 digit. This does not
include inaccuracies introduced by the user's potential and current transformers. Accuracy calculated at
1second average.
2. Specifications assume: voltage and current waveforms with THD 5% for kvar, kVA and PF, and
reference operating temperature 20°C - 26°C.
3. Measurement error is typically less than the maximum error indicated
