  Figure 1: Connection Diagram

Put one conductor only within the jaws on inside section of the 

indicated marks as much as possible in order to meet the accuracy of 

specifi cations. Make sure the clamp is vertical to the conductor.

To push and release the yellow button for 40 A range and lock the button for 400 A range.

Release  

~ 40 A

~ 10 mV/A

Lock  

~ 400 A

~ 1 mV/A

AC current can be measured without removing the conductor out of the circuit by following the procedures 

as shown below:

1. 

Plug the BNC of cable to the BNC with dual banana plugs, and then plug into the V/COM terminals on 

 

multimeter. For oscilloscope, plug the BNC connector directly to oscilloscope.

2. 

Set the ACV measurement and range on multimeter you used.

3. 

Position the jaw to a single conductor and center it accordingly to alignment marks.

4. 

Ensure that the arrow marked on the clamp jaw point towards the load of phase measurements or 

 

away from the load (toward the source) for neutral measurements.

5. 

Observe the AC value on a multimeter or the waveform on an oscilloscope which is proportional to the 

 current.

6. 

Select a lower range on the Clamp-on adapter and set the corresponding sensitivity (mV/ A setting) 

 

on the oscilloscope if required.

Calibration Equipment 

        

The pre-calibration guidelines are shown as follows:

• 

Be sure you  are a qualifi ed person to perform the calibration

• 

The environment should be 23 °C ±2 °C and the relative humidity (RH) shall be < 80%.

The test equipment requirements listed in table below or equivalents are required to perform the calibration 

and performance verifi cation test procedures. Alternative equipment may be used as long as the accuracy is 

as good as or better than the specifi cations listed.
