See the second photo. Details about the fuse are included on the back of the meter's case, but it is easy to miss them. See the yellow arrow. The fuse is 0.5A at 250 volts. The size is 5mm x 20mm.
See the third photo. This is the fuse in the factory supplied holders.
See the fourth photo. The factory fuse holders are more flimsy than any I have ever before seen. When the fuse is removed, the holders move. The holder on the right feels especially loose and marginal. If they were made of heavier material, I would simply resolder them. But, I want to replace them. (I could just solder the fuse to leads, but I want replacement of a blown fuse not to require a soldering iron.)
Step 1: First steps
See the second photo. Ream away rough edges and clean the inside of the brass tube with a round file.
- Tubing cutter
- Round file
- Soldering iron and solder
- Small scissors
- Pair of pliers
- Heat source (hair dryer, match, etc.)
- 9/32 O.D. brass tubing
- Heat shrink tubing
Step 2: Fitting the tubing
See the second photo. I used a pair of pliers to make the tubing fit the fuse. It was still a little loose, so I crimped the tubing just a little without the fuse to get a closer fit. Caution: These little glass fuses are delicate. I broke one by pushing too hard on it.
