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 1-second average.

2. Specifications assume: voltage and current waveforms with THD ≤ 5% for kvar, kVA and PF; reference operating

temperature: 20°C - 26°C.

3. Measurement error is typically less than the maximum error indicated here.

4. Accuracy of the device without CT complies to IEC 62053-22 class 0.5S standard
