Why Does Multimeter reading keeps jumping?
Whether it’s Analog or Digital Multimeter, for beginners and potential starters can be reasonably hard to understand if someone doesn’t practice the basics or use Multimeters without learning how to operate it.
Even professional users can sometimes have these kinds of issues where they can’t understand what went wrong, or it could be broken.
Whether it’s time to invest in a modern one
In this article, we look at why Multimeter readings keep jumping and don’t present accurate readings and to check what could be wrong.
Maybe the jumps of readings could mean that the multimeter might be broken or the accessories might be faulty or broken. Sometimes it could be due to auto-ranging feature. Usually, multimeter readings should not keep on jumping if you are measuring something. Here are some tests and solutions for how to check if the multimeter is working properly or not.
List of Tests to try:
- Check if burning or strange smell is coming from the Multimeter to ensure that the fuse or its internal component is not burned.
- Examine it with other Power sources for example small battery to see if it’s working with other components.
- See if you have selected the appropriate scale before implementing the probes on the tested equipment.
- If you have any other spare multimeter try using it to detect the fault in the Multimeter, check the fuse to see if it’s burned.
- Properly check if the probes or the probe wires are working properly. See if they are broken or burnt.
- If your Multimeter contains an auto-ranging feature then try to carefully turn it off and then try to test again if it works properly.
- If your Multimeter typically requires a Power Source or Battery see if they are working alright.
If all these practical tests fail to try going to an Electronic repair shop to get it properly checked before you go to buy a new and best digital multimeter or analog multimeter.
Use safety gloves and protective gear before performing these tests to ensure protection.Be Safe
