FUSE REPLACEMENT

Refer to Figure 2B and use the following procedure to examine or replace the meter's fuse:
1. Perform steps 1 through 3 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 prying 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 circuit board switch both are in the OFF position.
6. Replace the case top and case bottom. Make sure that all gaskets are properly seated and 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.
