How To Check 240 Voltage with a Multimeter?

Yes, it is very important to know how to check the voltage on your outlet or circuit to troubleshoot the problem that may occur in your home. The easiest way to check the voltage is by using a multimeter. If you want to check voltage from 110V to 240V the procedure will be the same, just be with me. Simultaneously, this will give you knowledge regarding which devices are suitable for that circuit. All in all, this article will show you how to check 240 voltage with a multimeter. It may help a DIYer who wants to learn more about electricity and multimeter usage.

“Let’s Break down a few thing before starting our Voltage testing guide.”

First, you need to understand the difference between volts and amps. Voltage measures how much force is behind the flow of electrons, while amps measure the actual number of electrons flowing past a given point in a circuit per second.

Tools Needed

A multimeter is a tool used to measure voltage, resistance, and current. It is an essential tool for electricians as well as DIYers.

Types of the multimeters

Digital multimeter: A digital multimeter uses a digital display to show the readings. It is the most common type of multimeter and is easy to use.

Analog multimeter: An analog multimeter uses a needle to point to the readings on a scale. It is less common than a digital multimeter but can be more accurate.

In this case, you can get any of the multimeters according to your ease. Both types of multimeters check current, resistance, and voltage. If you haven’t decided which multimeter is best for you then  have made a list of best budget multimeters for you 🙂

Checking 240 voltage with a multimeter

Step by Step Guide

Step 1: Identify the outlet you want to test.

Outlets and circuits can be identified by their type of opening. There are two types of openings- round and flat. Outlets with a round space are typically used in North America, while outlets and circuits with a flat opening are usually used in Europe and other parts of the world.

If you want to test the voltage at an outlet, you will need to identify the hot one of the three openings. The hot opening will have screws or a metal prong sticking out of it. The neutral opening will have two screws or a metal prong sticking out of it, and the ground opening will have a green screw or a metal prong sticking out of it.

Step 2: Setup the multimeter

To set up the multimeter, you must put the red lead on the hot opening and the black lead on the neutral or ground opening. Using an analog multimeter, you must set it to the 250V range. If you are using a digital multimeter, you will need to fix it to 400 volts, if you are testing 240 volts.

Step 3. Test 240 Volts with multimeters

If you have three opening outlets and are testing 220V, you need to put the two probes into two vertical openings; the reading should be 220 or 240V. You can also place the red probes in the vertical opening and the black probes in-ground or circular opening. If the task is 220 to 240 V., Then all is good. If the reading is not between this number, then your circuit has a problem. So now you know how to check 240 voltage with a multimeter. 

Wrapping Up!

Following the steps above, you can quickly an easily check the voltage at your outlet or circuit. If you are not getting the correct voltage readings, then your circuit has a problem, and you should contact an electrician. I have also made a guide on how to check short circuit for you as well so don’t miss it out too. Checking the voltage at your outlets and circuits is a simple and easy way to troubleshoot any issues in your electrical system. 


Can a multimeter measure 240 Volts?

Yes, a multimeter can measure 240 volts. If you use a digital multimeter, you will need to set the multimeter to the 240-volt setting. Using an analog multimeter, you must set it to the 2-volt range.

Are 220 and 240 volts the same?

No, 220 volts and 240 volts are not the same. Two hundred twenty volts is the standard voltage in North America, while 240 volts is the standard voltage in Europe and other parts of the world.
