How do you fix a broken multimeter?
Check for loose parts or screws inside the multimeter’s case and fix them in the appropriate way. Reassemble your digital multimeter, set it to measure resistance, and touch the probe leads together. It should read well under one ohm. The Digital Multimeter Troubleshooting and Repair is a basic repair process.
Why is my multimeter not getting accurate measurements?
If the multimeter powers on, but you are not getting accurate measurements, the problem could be with the test probe leads. In order to check, set the electronic multimeter to read resistance, and then touch the ends of the probe leads together. You should get a reading of 0 ohms (or infinity ohms if working with an analog multimeter).

How do you test a lead with a multimeter?
Test the leads To "ohm-out" your leads, place your DMM in the resistance (ohms) function, plug the leads into the DMM and touch the probe tips together—red to black. The meter should read about 0.5 ohms or less for good quality test leads. You may isolate a problem to one lead or the other by testing them separately.

Why is my multimeter not reading current?
If you try to measure the current with a blown fuse, you'll probably notice that the meter reads '0.00' and that the system doesn't turn on like it should when you attach the multimeter. This is because the internal fuse is broken and acts as a broken wire or open.

Step 1: Step One
This is a pretty basic job requiring minimal skills, materials and tools. A 6 penny finish nail, an old pen barrel sans ink "tube," soldering iron and solder (not shown), a bit of heat-shrink tubing, an X-Acto knife (or substitute) (not shown either) and our favorite, a hot glue gun and glue (also not shown). I measured the ink barrel against the non-broken test lead for length then cut the barrel to length (measured from the tip).
Step 2: Step Two
After exposing about an inch (2.5 cm) of the wire I made a quick wrap around the head end of the finish nail and soldered them together.
Step 3: Step C
After the new lead tip cooled, (its now graduated from being a simple nail to an integral part of a precision instrument), I slid on the heat-shrink tubing that will cover the to-be-glued end and then popped the newly tipped wire lead down into the pen barrel letting about 3/4" (1.75 cm) of the once lowly nail protrude through the pen barrel tip. I then hot glued around the wire end, filling up some of the ink barrel.
Step 4: Step Last
And that's it. If I had them, I would have used a red pen and red heat-shrink tubing. But since I had neither I'll just have to live with it. Total cost: $0.00 (US) as I had everything already...I'll bet you do too. Thanks for reading this far...
Step 1: Preparing the Leads
If the probes are broken at the either of the end points, some amputation may be required. This was the case with my probes. I cut off some of the 90° arm to get at the wire.
Step 3: The Fix!
Once you have your blackened thermoplastic, you are ready to fix the probe.
