Replacing Fuses in Digital Multimeters

If your multimeter stops reading amperes you may have blown a fuse! In most cases, you will still be able to read the resistance, voltage, and other values.

The most common fuses in multimeters are certain glass and ceramic fuses like Bussmann AGX-2, GDA-630mA, and SIBA ceramic fuses. You may also have fast-acting ceramic fuses with various milliamp ratings and we stock just about every single one!

View all ceramic fuses here.

Depending on your multimeter you may have one or more of these fuses to replace. The process is very straightforward: remove the back of your multimeter, pop the blown fuse out, and slide the new fuse in. 

For precise instructions we recommend consulting the manufacturer’s manual; each multimeter is slightly different!

If you can't find the fuse you need please contact us!

 

Replacing fuses in your Fluke digital multimeter

 

 

To start, take the back off of your multimeter or remove any casing. We recommend consulting the manufacturer's manual as each model is slightly different. You should be able to easily locate any fuses inside.

Fluke has a lot of different part numbers and some are for the exact same fuse. This chart shows the fuse part number and the corresponding Fluke part numbers:

If you need to replace a DMM fuse you can use either DMM or DMM-B part numbers. They are identical in both fit and function and are completely interchangeable. We stock the B fuses.

There are newer styles with a -R ending indicating that they are RoHS compliant - they are lead-free, that’s the only difference.
