REPLACING THE FUSES 

WARNING

: To avoid electric shock, disconnect the test 

leads from any source of voltage before removing the fuse 
door. 

1. 

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

2. 

Open  the  fuse  door  by  loosening  the  screw  on  the 
door using a Phillips head screwdriver. 

3. 

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

4. 

Install the new fuse into the holder. 

5. 

Always  use  a  fuse  of  the  proper  size  and  value 
(0.2A/250V fast blow for the 200mA range, 10A/250V 
fast blow for the 10A range). 

6. 

Put the fuse door back in place. Insert the screw and 
tighten it securely.
