SAFETY INFORM ATION 

 

Read  the  follow ing  safety  information  carefully  before 

attempting to operate or service the meter. 

 

To avoid damages to the instrument do not apply the signals 

w hich  exceed  the  maximum  limits  show n  in  the  technical 

specifications tables. 

 

Do not use the meter or test leads if they look damaged. Use 

extreme caution w hen w orking around bare conductors or bus 

bars. 

 

Accidental contact w ith  the conductor  could  result  in  electric 

shock. 

 

Use the meter only as specified in this manual; otherw ise, the 

protection provided by the meter may be impaired. 

 

Read  the  operating  instructions  before  use  and  follow   all 

safety Information. 

 

Caution w hen w orking w ith voltages above 60V DC or 30V AC 

RMS.  Such voltages pose a shock hazard. 

 

Before  taking  resistance  measurements  or  testing  acoustic 

continuity, disconnect circuit from main pow er supply and all 

loads from the circuit.
