Introduzione

This guide will explain how to replace the .440 and 11 Amp fuses. Both fuses can be removed and replaced the same way, so either one can be replaced using this guide. Remember to put the each fuse in its correct socket based on its current rating. To make sure that your replacement fuses are compatible with the Fluke 77 Series III Multimeter, refer to the back panel fuse rating label or the Service Manual.

    • Replace a fuse only with a fuse identical in type, voltage rating, and current rating as specified by the back panel fuse rating label or the Fluke 77 Series III Service Manual. Inserting the wrong replacement fuse could create a fire hazard.

    • Locate the fuses near the bottom left corner inside the device.

    • Take note of which fuses belong in which location before removal. They are NOT interchangeable.

    • The .440 Amp fuse is located in the upper left hand fuse holder.

    • The 11 Amp fuse is located in the lower right hand fuse holder.

    • Lift the rounded edge of the fuse with one finger until that side is completely out of its holder.

    • Grab the lifted edge of the fuse between your thumb and forefinger and pull it the rest of the way out of the device.

    • The fuse in the upper left corner can be tricky to remove. Use a plastic opening tool if needed.

    • Repeat steps 4 and 5 to remove the other fuse if you are replacing both fuses or if you are replacing a different part further on.

To reassemble your device, follow these instructions in reverse order.

Don’t see a fuse on mine. No brand name. New battery. Continuity buzzer not working. And, Voltages Both AC/DC) show . When n ot connected to a voltage. ? Nothing looks out of place. Looks clean inside. Only thing i can think of is trying to get to the switch. That doesn’t look easy. Printed circuit board has to be pryed out. Looks like. WAIT,ther does look like a place for a fuse. But,,nothing there. How didi it work,,at all. Have had it for about 13 years.
