REPLACING THE FUSES 

WARNING

:  To  avoid  electric  shock,  disconnect  the  test 

leads  from  any  source  of  voltage  before  removing  the 
fuse/battery cover. 

1.    Disconnect  the  test  leads  from  the  meter  and  any  item 

under test. 

2.    Remove  the  fuse/battery  cover  by  loosening  the  two 

screws using a Phillips head screwdriver. 

3.    Remove the old fuse from its holder by gently pulling it   

out.   

3.  Install the new fuse into the holder. 
4.  Always use a fuse of the proper size and value     

(0.8A/250V  fast  blow  for  the  600mA  range,  10A/250V 
fast blow for the 10A range). 

5.  Replace the battery cover and secure with two screws. 
 

WARNING

:  To  avoid  electric  shock,  do  not  operate  your 

meter until the fuse door is in place and fastened securely.
