How to Test a Fuse with a Multimeter

Some of the most common uses for a multimeter are measuring voltage and resistance, but it can also be used to test if batteries or fuses are working properly. We’ll explore this further today by looking at how you use your meter when testing an electrical device that has been interrupted remotely – such as with blown fuses.

What is a Fuse and What Does It Do?

The fuse is a very important device because it helps manage the flow of electricity when there’s an issue with your power supply. It can be used for things like protecting against short circuits and lightning strikes, so you don’t have any accidents.

What Is a Multimeter?

It’s a portable device that measures voltage, current and resistance. It can also conduct continuity tests to find out if two wires are Touching each other or not by sending an Electric pulse through one of them while measuring how much energy gets reflected back at you from the second wire with this special meter called “return loss”. This way we know which direction contains high concentration of electricity! Some advanced models have infrared thermometers built right into their heads so no need for bulky equipment anymore- just point & click on any surface near where things normally go cold.

How to Test a Fuse with a Multimeter?

Follow the steps below to use a multimeter to test a fuse of any rating.

Step 1

Take out your multimeter and switch it ON. Select the resistance function by using the dial switch.

Step 2

Take a fuse and put it on the table. This is to avoid its contact with any other conducting materials, such as metal or plastic surfaces that might cause an electrical shock if touched by one of these fuses incorrectly handled during installation procedures for your project.

Step 3

With the multimeter test probes, connect it to either end of your fuse. Choose 200 ohms for the lowest resistance range and see if there is any power flow through those connections.

Step 4

Since the display shows 1.5 ohms, we can safely assume that your fuse is in good shape and does not need to be replaced just yet.

Fuses are very important for protecting your home. If you notice that one of them has no power, then it’s time to replace the blown fuse with an authentic spare!

A multimeter is used in testing fuses by measuring how much current can pass through certain filaments until they break or melt under high temperatures – which means these devices will never give off any sparks when attacking another material like lightning would do if surrounded by dry grass/different types wood etc.

In order to avoid shocking yourself or causing a short circuit, always switch OFF the power before testing any fuses.
