15.3.5. CURRENT SENSOR CHARACTERISTICS (AFTER LINEARIZATION)
Sensor errors are offset by a typical correction inside the device. This typical correction, applied to the phase and amplitude,
depends on the type of sensor connected (detected automatically) and the gain in the current acquisition channel used.
The RMS current measurement error and phase error are additional errors (which must therefore be added to the device errors),
indicated as influences on the calculations carried out by the analyser (powers, energies, power factors, tangents, etc.).
