Potentially dangerous voltages may be present on front and rear panel terminals.  Follow all warnings in 

this manual when operating or servicing this instrument.  Dangerous levels of energy may be stored in 

capacitive devices tested by this unit. 

Always make sure the high voltage indicator is 

not

 on when connecting or disconnecting the device under 
test.

 

 
 

 

Product will be marked with this symbol (ISO#3684) when it is necessary for the user to refer to 

the instruction manual in order to prevent injury or equipment damage.

 

 

   

Product marked with this symbol (IEC417) indicates presence of direct current. 

 

  

 

Product  will  be  marked  with  this  symbol  (ISO#3684)  when  voltages  in  excess  of  1000V  are 

present.
