Explanations
1) Reference to amplitude.
2) Reference to phase and amplitude.
3) Reference to basic oscillation
4) Reference to effective value.
5) The accuracy class will degrade by
one step when measured with
a ../1A-current transformer.
6) Calculation from fundamental harmonic oscillation.
7) Precision class 0.5S per IEC62053-22
