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  testing 

acoustic continuity, disconnect circuit from main power 

supply and all loads from the circuit.
