AUDIBLE CONTINUITY TEST   

1.

 

Set the function switch at    position. 

2.

 

Connect test leads to two points of the circuit to be tested. If the 

Resistance is less than 50Ω,buzzer will sound. 

DATA HOLD APPLICATION 

      D-H button is used to hold a measuring result. When this button 

is Pushed, LCD will keep the last reading until pushing this button 

again or rotating the function switch. 

BATTERY&FUSE REPLACEMENT 

      If  the  sign  appears  on  the  LCD  display,  it  indicates  that  the 

battery should be replaced. Remove the screw on the back cover 

and  open  the  Case.  Replace  the  exhausted  batteries  with  same 

types. 

      Fuse  rarely  need  replacement  and  blow  almost  always  as  a 

result of  Operator’s  error  .Open the  case  and  replace  blown fuse 

with same ratings. 

WARNING 

      Before  attempting  to  open  the  case,  always  be  sure  that  test 

leads  have  been  disconnected  from  measurement  circuit.Close 

case and tighten Screws completely before using the meter to avoid
