There are many gadgets that can measure the amount of electricity any system uses. It is important to know where to plug it in, as well as understanding the appropriate charge and battery needed. A system won’t power up with too little energy and may get damaged with too much power.

Using an Electronic Multimeter

How to Repair an Electronic Multimeter

Here are the steps to follow to repair your electronic multimeter and have it functioning like normal again :

  1. Check Battery

Turn on the electronic multimeter. If it doesn’t power up or the screen is dim, then it may just be a battery problem. Replace the battery or charge it. Some multimeters show the battery levels, so you’ll be able to evaluate that problem quickly. If it still shows problems, move on to the next step.

  1. Test Probes

If you aren’t getting accurate measurements, then the test probe leads may be the trouble. Set the electronic to read resistance. Touch the ends of the probes. If you’re getting ratings over 1 ohm or erratic leads, then install new test probe leads.

  1. Disassemble the Electronic Multimeter

If replacing the test probe leads isn’t the problem, then disassemble it to evaluate the problem that lies inside the multimeter.

  1. Check Fuse

Remove the fuse and check if the wires inside it are burnt or blown. You can find it easily if the fuse is made of glass. If not, then check its resistance using another multimeter. Replace the fuse if no resistance shows. You can find the right fuse recommended on the owner’s manual.

  1. Re-solder Wires

Check for any broken or rusted wires or connectors. You can re-solder the wires to fix the problem.

  1. Check for Loose Parts or Screws

There may be loose parts or screws that might have been separated from where it’s supposed to be. Give your multimeter a gentle shake, or use a magnifying glass to see if there are any loose or lost screws.

  1. Reassemble and Test

If you have fixed the multimeter and see no problem, then reassemble it and check for resistance again. If it’s under 1 ohm, then the multimeter works. If not, then it’s best to either replace the multimeter or have it replaced.
