Explanations
1) Reference to amplitude.
2) Reference to phase and amplitude.
3) Reference to basic oscillation
4) Reference to effective value.
5) Accuracy class 0.2 with ../5A converter.
Accuracy class 0.5 with ../1A converter.
* The display returns to 0 W once the max.
total working value range has been reached.
6) Calculation from fundamental harmonic oscillation.
7) Accuracy class 0.5S according IEC62053-22
