OPERATION CONDITION & CONNECTlON 

   

!  WARNlNG 

 

POSSIBLE ELECTRICAL SHOCK   

  This instrument is for the use of low voltage circuit.   

Do not make measurements of power lines carrying more than AC500V.   
Before use, check and confirm the voltage of circuit to be measured.   

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

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 
is wrong with the CT cables.   

● 

When replacing the batteries, remove the instrument from all measuring 
circuits. 

  Do not load the voltage exceeding AC10V to the input & output terminals of 

instrument body.

CAUTION

 

 

FOR SAFETY USE   

  Do not drop the instrument & CTs and or do not give the strong shock .   

  Do not put heavy goods on the cables of instrument, CTs & Accessories and 

do not modify those cables.   

 If dropping CTs and or giving strong shock, the joint surface of CTs are 

damaged and it may cause wrong influences to the measurement.   

  To avoid defect of CTs due to the break of cables, do not bend and or pull the 

cables at the base of CTs. Handle them very carefully.
