SAFETY INFORMATION 

 

Read  the  following  safety  information  carefully 

before  attempting  to  operate  or  service  the 

meter. 

 

To  avoid  damages  to  the  instrument,  do  not 

apply  the  signals  which  exceed  the  maximum 

limits  shown  in  the  technical  specifications 

tables. 

 

Do not use the meter or test leads if they look 

damaged.  Use  extreme  caution  when  working 

around bare conductors or bus bars. 

 

Accidental  contact  with  the  conductor  could 

result in electric shock. 

 

Use the meter only as specified in this manual; 

otherwise, the protection provided by the meter 

may be impaired. 

 

Read the operating instructions before use and 

follow all safety Information. 

 

Caution when working with voltages above 60V 

DC  or  30V  AC  RMS.  Such  voltages  pose  a 

shock hazard. 

 

Before  taking  resistance  measurements  or
