Users Manual

If the voltage exceeds the swell voltage threshold for longer than one cycle, a swell event will be recorded.

Voltage Sags

Sags are decreases in line voltage lasting for at least ½ cycle. Sags are only measured on the hot-neutral lines. Typically, a sag will be a few volts or tens of volts below normal.

If the voltage drops below the sag threshold a sag event will be recorded. If it drops to below 70Vrms the event will be recorded as an outage.

Line Frequency Variations

Frequency variations are changes in frequency above or below the nominal frequency (60Hz in North America, 50Hz in Europe, for example). Variations in frequency are typically a few cycles and can be from seconds to minutes in duration.

If the frequency drops below the minimum threshold a low frequency event will be recorded; if it exceeds the maximum threshold a high frequency event will be recorded.

For a 120V recorder version the frequency will default to 60Hz.
