How to test a fuse with a digital multimeter

You can check the fuse while it still in circuit. Connect the probes and set the dial to test for continuity.

Here are some continuity testers that I found for you they are cheap.

How to test a fuse with a digital multimeter. Heres how to test a fuse with a digital multimeter. Turn the wheel to ohms. This option is represented by the Omega symbol.

This option is represented by the Omega symbol. Next up grab the red and black leads and put them across each other to make sure the multimeter is working. How to Check a Fuse by Testing it with a Multimeter presented by Katie Nyberg for Galco TV.

Buy the items featured in this video at 800-337-1720 or visit. Set up the multimeter. Connect the probes and set the dial to test for continuity.

Touch each probe on one of the fuses leads or contacts. Just like with the previous types a beeping multimeter is a good sign that the fuse is fine. Otherwise the fuse has blown and needs replacing.

Httpbitly2GSdqwqLearn how to easily test your Digital Multimeters fuses without having to open the case using the ohms function and test leads. To test a fuse in the circuit with power. Set the meter to read voltage ac or dc depending on the circuit the fuse protects.

Measure from ground or neutral to each side of the fuse. If the fuse is good you should read supply voltage on one side of the fuse and the same value on the other side. Now that we know the basic terminology we finally come to the steps to test a fuse using a multimeter.

Turn the car and the equipment that the fuse is a part of off. After you do this remove the fuse by gently pulling it out of its slot. Verify that no voltage is present.

Set your meter to continuity and place your leads on the line and load side of the fuse. If the continuity tone sounds and your meter displays a low resistance value the fuse is good. If your multimeter displays OL and no tone sounds the fuse needs to be replaced.

Set your multimeter on OHMS for resistance measurement before you run your test on your fuse. Put the negative and the positive leads altogether and check out the readings. The figure shown needs to be close to that one displayed when you run the test on the fuse.

Here are the critical steps that you should consider following when testing fuses using a multimeter. First and foremost ensure that the black lead is connected to the common socket while the red lead is connected to the Ohms socket which is indicated with this symbol Ω. Once this is done you should move the dial to the lowest range of your Ohms scale which is often 200Ohms on multimeter.

Measure the fuse with a either an analog or a digital multimeter. If you use an analog meter then select the lowest ohms range which is the x1 ohms. Touch the probes to both end of the fuse.

You can check the fuse while it still in circuit. A good fuse reading should showed continuity or read ZERO ohm. We test fuses using the continuity mode because the main concept when it comes to how fuses work is continuity.

If a multimeter detects no continuity you know that the fuse is broken. This can happen because a fuse served its purpose and burned out thus breaking the continuity or it is possible that due to age or due to force in case that the fuse fell or took a hit the string or wire inside the fuse broke. A digital multimeters Continuity Test mode can be used to test switches fuses electrical connections conductors and other components.

A good fuse for example should have continuity. A DMM emits an audible response a beep when it detects a complete path. Visually check the wire inside the fuse.

If the wire is broken the fuse is blown and it needs to be replaced. Below is a picture of a usable fuse on the left and a blown a fuse on the right. Test the Fuse with the Testing Leads.

Place a testing probe on each. To test if the fuse is blown we require a multimeter. Once configured a multimeter can measure the resistance of the fuse element.

Resistance is measured in Ohms Ω. The following tutorial uses a digital multimeter however the same principles apply when using an analogue multimeter ie. To test a fuse simply contact the probe and clips to the end of the fuse as you would with a multimeter.

The fuse is operating if the tester lights up. Before testing make sure there is NO electricity flowing through the fuse. Here are some continuity testers that I found for you they are cheap.

With this method you can test the fuses without removing them but you could also test the fuses manually. Open the back housing of the multimeter and pop the fuses out. Set the multimeter to.

First lets understand how you can use EverStart Digital Multimeter for continuity testing. This type of test is utilized to test the path for current flow. Its also employed to test conductors electrical connections fuses and switches.
