Press SAVE or ENTER keys (or the smart icon

) to save each selection and confirm by

“Ok”. The main screen of Fig. 85 is shown by meter at the end of the operation.
Press ESC key (or the smart icon ) to quit without saving and back to previous screens.
The selection parameters of harmonic analysis require the preliminary selection of
voltages or currents inside General Parameter sub-level. The below error screen are
shown in these cases:

5.4.7. Voltage Anomalies
This option permits to set the control parameters relative to voltage anomalies (sags,
swell, supply breaks – see § 10.1) recording which is completely independent from
periodic analysis (regulated by integration period). The below screen is shown by meter:
