Verify connections to the measurement line.
Connect the instrument to the measurement line, referring to the connection diagram shown on the screen.
Attach voltage cords to measurement lines
Securely clip the leads to metal parts
such
as terminal screw terminals or bus bars.
(Example: Secondary side of breaker)
Current flow direction arrow
Make certain that the current
flow direction arrow points
toward the load side.
Verify that the connections are correct, referring to the vector
diagrams and measured values on the [Wiring] screen.
If you discover an error, verify the connections and return to
step (2) to reconfigure the initial settings.

Settings such as the current range, nominal input voltage, measurement
frequency, and event thresholds will be automatically configured based
on the selected connection mode.
(You will need to set the measurement line type, current sensor type, and external VT/CT ratio.)
Select from the five available patterns according to your objective. To investigate the cause of a
power supply issue, select the abnormal voltage detection pattern. To investigate power supply quality (i.e., to monitor a power system), select the basic power supply quality measurement pattern.

Setting Contents Description
Voltage event
detection
Monitors voltage factors (dips, swells, interruptions, etc.) and frequency to detect events.
This pattern is used to investigate the cause
of equipment malfunctions. The TIMEPLOT
interval will be set to 1 minute.
Standard Power
Quality
Monitors voltage factors (dips, swells, interruptions, etc.), frequency, current, voltage and
current harmonics, and other characteristics
to detect events. This pattern is primarily used
to monitor systems. The TIMEPLOT interval
will be set to 10 minutes.
Inrush Current
Measures rush current. The TIMEPLOT interval will be set to 1 minute, and the rush current threshold will be set to 200% of the RMS
current (reference value) set during simple
configuration.
Record measured
value
Records measured values over an extended
period of time using a TIMEPLOT interval of
10 minutes. All event detection functionality
other than manual, start, and stop events is
turned off.
EN50160
Performs EN50160-compliant measurement.
Standard-compliant evaluation and analysis
can be performed by analyzing data using the
application software PQ ONE, which is supplied with the instrument.
For more information about settings, see the
instruction manual.

Applying clamp sensors to lines to be measured
Always clamp the instrument around only one conductor.
Clamping the instrument around two or more of conductors
in a bundle prevents the instrument from measuring any
current regardless of whether the measurement target is a
single-phase or three-phase circuit.

Verifying settings and connections
-2. Are too many events occurring?
(Is the icon shown continuously?)
If too many events are occurring, check which events are being
generated on the event list on the [EVENT] screen (see step 7)
after recording some data
and then change the thresholds for
the problematic events.
Alternately, wiring (connections) to the measurement line may
be incorrect. Verify the connections.
-3. Are the voltage and current phase relationships
shown properly in the vector diagrams?
If not, the wiring (connections) to the measurement line or current sensor orientations may be incorrect. Verify the connections
and current sensor orientations.

Push

Push to

Accept
The time can only be changed when
the [Time Start] setting is [Time].
-1. Are measured values or crest factors out of range?
If you see any warning indicators, the clamp sensor, range, or
connection settings may be incorrect. Verify the connections and
return to step (2) to reconfigure the initial settings.
Warning indicators: Values shown in red as below.
-4. Are waveforms and measured values shown properly?
If waveforms and measured values are not shown properly, the
clamp sensor, range, or connection settings may be incorrect.
Return to step 2 to reconfigure the initial settings. Alternately, wiring (connections) to the measurement line or current sensor orientations may be incorrect.
(Voltage and crest factor out of range)

Event icon
Normally shown in white
but turns orange when
too many events occur.
No. of events recorded
Up to 9999 events can be recorded. (when [Max. recordable
events]
is set to [9999].)
Measurement data continues to be recorded even when the
number of events exceeds 9999.

Creating reports
Output information shown on the screen as-is in the form
of a report. Create reports that suit your needs without
the need to configure complex settings.
Viewing data
Use event statistics functionality to analyze measurement
data at a high level of detail. By reviewing event occurrence
by date or time, you can discover events that are likely to
occur at a specific time or on a specific day of the week.

CSV format so that it can be opened with a spreadsheet
application on a computer.
Easily create graphs to suit your needs
Organize time plot graphs by convenient times or group
three phases of data together on a single graph.
