to analyze your system.
To this purpose, voltages and currents are monitored, so as to find:
• voltage sequences (Over, Under, Pos and neg)
• unbalance between voltages (Unbalance)
• short voltage drops (Interruption) and slow sags (Sag)
• short voltage increases (Spikes) and slow swells (Swell)
• harmonic distortion of voltages and currents (THD)
Each monitoring is associated with control parameters set by the user and updated each time the set
control conditions occur.

The Monitor time parameter, which defines the length of each monitoring session, can also be set in the
Settings menu.
NOTE: the parameter is the one used for measuring the maximum currents and voltages
