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.
