4. Connecting voltage sensors to the measurement target
1
Refer to the wiring diagram to check
the locations to which you have
connected the voltage sensors.
2
Connect the voltage sensors to the
secondary side of the breaker.
3
Check the readings.
In this example,the screen should indicate
approximately 220 V and 50 Hz if there is
no problem.
(Because the measurement target is a 220
V line,and the frequency being measured
is 50 Hz.)
4
Verify the results of checking the
wiring.

Move the cursor to item.
Press the Enter key.

Tip
The power source side of the breaker is called the primary
side; whereas the load side,the secondary side.
For your safety,connect the voltage sensors and the clamp
sensors to the secondary side.

5. Connecting clamp sensors to the measurement target
Tip
When the measured value is shown as 0 A
The zero-display processing
*
(which forces the display to read “0 A” when the reading is
0.4% of the range) may cause the display to read “0 A.” Try lowering the current range
while referring to “11.6 Range Conguration and Accuracy by Clamp Sensor” in the
instruction manual.
Reference
Clamp 1 conductor only.
OK
*Example: For the 500 A range,values that are less than or equal to
2 A (0.4% of 500 A) will be displayed as 0 A.

1
Refer to the wiring diagram
to check the locations to
which you have connected
the clamp sensors.
2
Connect the clamp
sensors to the secondary
side of the breaker.
3
Verify that measured
values are being displayed.
4
Press the F2 [NEXT] key.
6. Setting the current range
Tip
Set the current range based on the anticipated maximum load current that will
occur during the measurement period. (Refer to 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 over-range event during measurement,making
accurate measurement impossible. If the range is too high,a large error component
will result,making accurate measurement impossible.
Display range

Set the range.
In this example,
the instrument
is set to 50 A.

7. Checking the clamp sensor (current) wiring
1
Check measured values.
2
Verify the results of
checking the wiring.

Press the F2 [NEXT] key.
•Is the value low or negative?
Verify that the instrument has been
wired (connected) correctly.
Move the cursor to item.
Press the Enter key.
Check the contents of the dialog box and
correct the wiring.

Rec. start method: INTERVAL
Example: With the save interval set to 5 min.
Tip
If the SaveTime is shorter than the measurement period,the following
methods can be used to increase the available save time:
•Increase the SAVE INTVL.
•If there is any unnecessary data on the SD memory card,delete it or
reformat the card. (Exit the Quick Set and access the File screen.)

Congure settings as shown in screenshot below.
(SaveTime: It’s calculated automatically
by the free space of the SD memory card
and save items. Up to 1 year)
