WARNING

 
 
POSSIBLE ELECTRICAL SHOCK 

  This instrument is for the use of low voltage circuit. 

        Do not make measurements of power lines carrying more than AC 600V. 
        Before use, check and confirm the voltage of circuit to be measured. 

  Apply only the coated cables and do not clamp bare cables. 

  For high voltage current measurement, apply the instrument at low voltage 

corresponding field. 

POSSIBLE ELECTRICAL SHOCK OR ACCIDENT 

  Do not handle the instrument in the rain, at humid place, with a drop of water 

and or with wet hands.

 

  Do not use the instrument if the CT or CT case are damaged and if something
