Screw (i) Battery Cover (ii) 9V Battery Figure 2 25
4-3 Fuse Replacement Refer to Figure 3 and the following procedure to examine or replace the meter’s fuse: 1. Perform steps 1 though 3 of the battery replacement procedure. 2. Than remove the two screws from the case bottom and lift the case bottom until it gently unsnaps from the case top. 3. Remove the defective fuse by gently prying one end of the fuse loose and sliding the fuse out of the fuse holder. 4. Install a new fuse of same size and rating. Make sure the new fuse is centered in the fuse holder.
