Testing Fuses 

 
To test the internal fuses of the meter. 

1.

 

Turn the rotary switch to the Ω position. 

2.

 

To test FUSE 71 (Bussmann DMM-B-11A recommended), plug a test lead into VΩHz input terminal, 
and use the probe to touch the A input terminal. The display should indicate between 0.0 to 0.3Ω. 

3.

 

To test FUSE 72 (Bussmann DMM-B-44/100 recommended), plug a test lead into VΩHz input 
terminal, and use the probe to touch the mA input terminal. The display should indicate between 0.0 
to 2.5Ω. 

4.

 

If display reading is higher than the range, replace the fuse.
