What is a Multimeter?
First off, what is a multimeter, by the way? You might hear it many times already since this famous device is one of the must-haves at home.
A multimeter is a handheld electronic device that measures amps, voltage, and circuit resistance. This tool offers vast practical functions in the IT and electronic world, helping experts in cases like troubleshooting.

Your first step should be making sure that your outlet is working out properly. Set up the testing device by attaching it to the pointing probes. Next, turn on the multimeter and make sure to set the AC volt setting after.
As you can observe, outlets have vertical plugins; there, you must insert the probes correctly. Also, make sure to keep in mind that in North American standard outlets, type B outlet has a neutral spot on the left side, and on the right part is the live spot, while on the bottom is the grounded part.
About 110 to 120 volts are the correct power of outlets that work well. However, if your outlet did not reach the said voltage, you may repeat the process and check the result once again.
Finally, your next step is to connect the device to your car battery charger and have a thorough check. In this step, you only need to connect your car battery charger to the input jack of the multimeter.

Although multimeter can give you accurate data if your car battery is doing well, when checking the battery, might as well, check the power cord. Sometimes, you might suspect the charger for a different issue.
Don’t forget to take a look at the power cord; sometimes, the problem lies in there. Breaks in the wire or in its protective coating will cause damage. If you see such a case, do not plug in your charger, but instead, get some professional to repair it.
When Doing a Device Check, Safety Must Always be a Priority

As you can see, testing your car battery charger does not require so much knowledge. Also, as a car owner, it’s good to have a multimeter with you at home.
Since you already know how to test your battery charger, make sure to have it checked regularly. In this way, you are always ready in times of any battery emergency.
