Tip
Set the current range based on the maximum load current expected to ow during the measurement period.
(Consult the operating status, load rating, breaker rating, and other data to make this determination.)
If the range is too low, the instrument will experience an overrange event during measurement. The error component increases if the
range is too high. Current cannot be measured accurately in any of the above cases.
• Measured values of the channels are
low, or active power Psum shows a
negative value.
• Displacement power factor DPFsum is
below 0.5.
• The vector position is outside the
PASS range.
Refer to Section 4.9 on the Instruction
Manual.
Check the wiring judgment.

Threshold values for events and recording interval will be automatically congured.
To make any change to the event settings, press the [SETUP] key after
completion of Quick Set to display the Event Settings screen.
Voltage events
This is used to investigate the cause
of power supply abnormalities such as
equipment malfunction.
Voltage components (swell, dip, interruption)
and frequency are monitored.
The recording interval will be set to 1 minute.
Inrush current
This is used to measure the inrush current.
Event thresholds for inrush current is set
to 200% of current RMS and the recording
interval to 1 minute.
Trend record only
This is used to record measured values over
an extended period of time.
All the event settings (effective only for
manual events, recording start events, and
recording stop events) are set to OFF and
recording interval is set to 10 minutes.
EN50160
This is used to measure in conformance to
the European Norm EN50160.
The recording interval is set to 10 minutes.
(The recording interval is xed to 10
minutes. Cannot be changed.)
Refer to Section 5.3 on the Instruction Manual.
