A 1398 PQA Iron Current Clamp 

Current clamp operation 

 

Current clamp operation 

Step 1 

Connect A 1398 PQA Iron Current Clamps to the desired input on the measuring instrument. 

Step 2 

Clamp the probe around the insulated current-carrying conductor(s) to be measured. Make 
sure  that  probe  jaws  are  tightly  closed  around  the  conductor(s).  In  the  case  of  measuring 
current near live, naked conductor(s), remove electrical power from wires, before clamping 
(follow the requirements of EN 50191).
