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.
