4-3 Fuse Replacement
Refer to Figure 2B and use the following procedure to examine or replace the meter's fuses:
1. Perform steps 1 through 4 of the battery replacement procedure.
2. Lift the circuit board from the case top. Do not remove the screws from the circuit board.
3. Remove the defective fuse by gently lifting one end of the fuse loose and sliding the fuse out of the fuse holder.
4. Install a new fuse of the same size and rating. Make sure the new fuse is centered in the fuse holder.
5. Make sure that the case top rotary switch and the circuit board switch both are in the OFF position.
6. Replace the case top and case bottom. Make sure that the O-rings of case screws are properly seated, the
battery leads do not become pinched between the case halves, and the two snaps on the case top are engaged.
Reinstall the three screws.
