5.2.4.5 Accuracy

The RMS current measurement accuracy and the phase accuracy correspond to addition values (which must therefore
be added to the instrument's accuracy), indicated as influences on the calculations carried out by the instrument (powers,
energies, power factors, tangents, etc.).
The following specifications are considered to be in the conditions of references of the current sensor.
