Type of measurement lines
Set before proceeding to the next step.
Current sensor used
Set before proceeding to the next step.
*: Set the range switch of the sensor to
500 A when the current range of this instrument is set to 500 A or
50 A.
External VT Ratio, External CT Ratio
Set when attaching an external VT or CT. Set to 1 if not attaching an external VT or CT.
TIME PLOT Interval
Sets the TIME PLOT interval.
If the event icon ( ) is orange after performing quick setup (indicating that the event is being
detected continuously), it is recommended to check and reconfigure the event's threshold.

The 150 (50 Hz) and 180 (60 Hz) cycle settings provide the TIME PLOT intervals
required for IEC61000-4-30-compliant measurement. When using a measurement fre
