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.).

HYSTERESIS Hysteresis is a screening principle that is often used after detection of a threshold stage in Alarm mode (see §4.10) and in Inrush current mode (see §5.2). A correct hysteresis setting avoids repeated changes of state when the measurement oscillates about the threshold.
