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.

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.

see “3.6 Connecting
the Voltage Sensors to Target to be
Measured” in the instruction manual.
Improper application
Failure to apply the sensor properly will prevent you from being to
make an accurate measurement.
Example: 3-phase 4-wire 220 V line

Clamped with the
tips of the clip
Clamped too far
