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 cur-
rent sensor orientations may be incorrect. Verify the connections
and current sensor orientations.

You can change event thresholds, the recording
start date and time, recorded items, and other set-
tings as desired.

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, wir-
ing (connections) to the measurement line or current sensor ori-
entations may be incorrect.

a fan shape.
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.

Monitoring fluctuations in
measured values
You can view measured items in the form of a time series
graph. You can also display flicker values as a graph or list.
Press the TIMEPLOT key to display the [TIMEPLOT] screen.
You can change the screen display with the DF keys.

Starting recording
Press the START/STOP key to start recording. Data will be
automatically saved to the SD memory card.
• When recording, the operating mode indi-
cator on the top right of the screen will
show [Recording].
• To change a setting, set the operating
mode to [Setting]. (Settings cannot be
changed while recording or analyzing.)

Analysis
After recording has stopped, data can be analyzed on a computer
using the application software PQ ONE, which is supplied with
the instrument.
Display file data in list form
Drag and drop folders containing measurement data to
display a list of settings information and event occurrence
data for all the data contained in the folder.
Converting data
Convert event data and time plot data (binary data) to the
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.
To hold waveforms and values
Push
To active the key lock
For more information, see the PQ ONE
instruction manual (on the included CD-ROM).
Press and hold for at least 3 seconds.
To cancel the key lock, press and hold for
at least 3 seconds again.
Calculating demand and integral power
Display a demand graph, or display the maximum and
integrated power values for a specified interval.
To check instantaneous values
Push
(Switch screens with the DF key.)
Monitoring event
generation
You can check whether events are occurring and the num-
ber of events occurring with the event list.
Press the EVENT key to display the [EVENT] screen.
Event list
Select an event and press the ENTER key to view waveforms and
measured values at the time of its generation on the [VIEW]
screen.
Event list details
When multiple events occurred at the same
time, “1/N” (where N indicates the total number
of events) is displayed at the top of the list.
