5.3.  FUSE REPLACEMENT 

 

 

CAUTION 

 

Before replacing fuses, disconnect test leads from any energized circuit to 
avoid electrical shock. 

 

 

LEGEND: 

1.  Turn 

OFF 

the 

meter 

and 

disconnect  the  test  leads  from  the 
input terminals. 

2.  Remove the protective holster from 

the meter. 

3.  Unscrew  the  battery  cover  and 

remove the battery. 

4.

  Remove  the  defective  fuse  and 

install a new fuse of the same size 
and  rating  (fast  type  10A/1000V). 
Make  sure  the  new  fuse  is 
centered  in  the  fuse  holder.  Re-
screw  the  battery  cover  and 
reposition the protective holster.
