Reference graph for use when setting thresholds
You can adjust thresholds while viewing the present measured value and measurement waveform state.
Set thresholds are stored internally regardless of the event’s ON/OFF setting.
Even if a threshold is set, no events will be
generated unless the event is set to ON.
Events can be configured by pressing the DF3 ke
y to display the [Harmonics] screen. Settings can be
turned ON or OFF for each harmonic order.
Set thresholds are stored internally regardless of the event’s ON/OFF setting.
Even if a threshold is set, no events will be
generated unless the event is set to ON.
When the measurement frequency (fnom) is 400 Hz, me
asurement is limited to the 10th order.

Voltage waveform comparison
The
[U_Wave] screen can be displayed with the DF2 key.
A voltage waveform comparison event is generated when
the measurement waveform exceeds the waveform enve-
lope level. The waveform envelope level is set as a per-
centage of the nominal input voltage. When using a 3-
phase connection, the waveform envelope level applies to
the voltages of all 3 phases.
