= current fundamental
 @ 10% to 120% of voltage FS and 2% to 120% of current FS  Higher resolution is achievable via communications  Where the current is > 10% FS, the energy accuracy is better than 1.5% Rdg.  80% to 120% of voltage FS and 10% to 100% of current FS
Additional 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.
2. Specifications assume: voltage and current wave forms with THD ≤ 5% for kvar, kVA and PF; reference operating temperature: 20 - 26°C. 3. Ordinary measurement error is considerably less than the specified accuracy which indicates maximum error.
