either grip it with small pliers and gently lift the fuse out of the fuse-holder, or pry the fuse out of the fuse-
holder using a small screwdriver or knife blade.
After a fuse has been removed, check it using an ohmmeter, such as that found on modern digital voltmeters.
Do not trust a visual inspection of the fuse. A blown (open) fuse always should have a resistance of greater than
100 Ω. The resistance of a good fuse is very small.

Four replacement fuses should accompany every Counter/Working cell cable shipped by Gamry Instruments.
The Gamry Part Number for the small rectangular fuses is 630-00030. If you need to find replacement fuses
locally, we currently only recommend Very Fast Acting, 6.3 A, Nano Fuses from the Littelfuse corporation
(Littelfuse part number 045106.3MRL). Fuses with similar ratings from other manufacturers have not been
tested, so we cannot recommend their use.
Don’t forget the jackscrews when you re assemble the hood.
