WARNING: 

To avoid electric shock, do not operate the meter until the battery cover is in place and 

fastened securely. 

NOTE:

 If your meter does not work properly, check the fuses and batteries to make sure that they are 

still good and that they are properly inserted.  

 

 
 
 
 
 
 
 
 
 
 
 
 
 
REPLACING THE FUSES 

WARNING

: To avoid electric shock, disconnect the test leads from any source of voltage before 

removing the meter cover. 

1. Disconnect the test leads from the meter. 
2. Remove the protective rubber holster. 
3. Remove the battery cover (two “B” screws) and the battery. 
4. Remove the six “A” screws securing the rear cover. 
5. Gently remove the old fuse and install the new fuse into the holder. 
6. Always use a fuse of the proper size and value (0.5A/1000V fast blow for the 400mA range [SIBA 

70-172-40], 10A/1000V fast blow for the 20A range [SIBA 50-199-06]). 

7. Replace and secure the rear cover, battery and battery cover.
