SAFETY INFORMATION 

 

The digital clamp meter has been designed according to IEC1010 – 1 and IEC1010 – 

2  –  032  concerning  safety  requirements  for  electrical  measuring  instruments  and 

hand – held current clamps with an overvoltage category (CAT 

II

) and pollution 2. 

 

SAFETY SYMBOLS 

 

Important safety information, refer to the operating manual. 

 

Dangerous voltage may be present. 

 

Earth ground. 

 

Double insulation (Protection class 

II

). 

 

         

 

 

The  digital  clamp  meter  complies  with  the  requirements  of  the  following  European 

Community Directives: 89/336/EEC (Electromagnetic Compatibility) and 73/23/EEC 

(Low Voltage) as amended by 93/68/EEC (CE Marking). 

However,  electrical  noise  or  intense  electromagnetic  fields  in  the  vicinity  of  the 

equipment  may  disturb  the  measurement  circuit.  Measuring  instruments  will  also 

respond to unwanted signals that may be present within the measurement circuit. 

Users should exercise care and take appropriate precautions to avoid misleading   

 

SAFETY PRECAUTIONS 

Follow  all  safety  and  operating  instructions  to  ensure  maximum  personal  safety 

during  the  operation  and  to  ensure  the  meter  is  used  safely  and  is  kept  in  good 

operating condition.
