Once a fuse has been removed, it can be checked using an ohmmeter, such as that found on modern digital
voltmeters. A blown (open) fuse should always have a resistance of greater than 100 Ohms. The resistance of a
good fuse is very small.
Don't forget the jackscrews when you reassemble the hood.
Four replacement fuses should accompany every Counter/Working cell cable shipped by Gamry Instruments.
The Gamry Part Number for the small rectangular fuses is 630-00021. If you need to source replacement fuses
locally, we currently only recommend Very Fast Acting, 3.15 amp, Nano Fuses from the Littelfuse corporation.
The Littelfuse Part Number is 04513.15MRL. Fuses with similar ratings from other manufacturers have not
been tested, so we cannot recommend their use.
Always replace the fuses in a Reference 3000 cable with the recommended
fuse. Use of improper fuse, especially a fuse with a higher current rating,
could cause instrument failure if a battery cell is improperly connected. Use
of a non-approved fuse will void Gamry's factory warranty.
