4. Connecting voltage sensors to the measurement target

Refer to the wiring diagram to check

the locations to which you have 

connected the voltage sensors.

Connect the voltage sensors to the

secondary side of the breaker.

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.) 

Verify the results of checking the 

wiring.

Press the 

F2 [NEXT]

 key.

All results are 

 .

Move the cursor to 

  item.

Press the 

Enter

 key.

Check the contents of the dialog box 

and correct 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.

Improper application

Failure to apply the sensor properly will prevent you from being to 

make an accurate measurement.
