Adjust the multimeter to read 120 volts.

If your multimeter doesn’t show around 240 volts, there may be a problem with one of the circuits.

Two 120-volt circuits in series with your multimeter result in a 240-volt output. Take a look at what your multimeter is showing you.

One end of each test probe should be inserted into one of the angled 120-volt slots, and the other end should be inserted into the next similar slot.

Avoid getting shocked by touching the probes at any time, but especially when their metal tips are exposed.

Insert the black and red test probes into your multimeter, and set the dial to the 240 V AC range.

Two of the slots are for carrying 120 volts each, while the third is for grounding the device. Each outlet in a 240-volt wall plate typically has three prongs: two parallel slots angled at 45 degrees (occasionally vertical) and a third slot that is lower than the other two.

Learn the arrangement of your 240-volt outlet by observing it closely.

Do not try to plug in your dryer if the volt measurements do not match the appropriate voltage.

Plug in your dryer’s power cord after testing your 220V outlet with a multimeter and getting positive findings that give you the go-ahead.

Remember to unplug the test leads and power down the multimeter when you’re finished. The voltage shown on the screen should be between 110, and 120 V. You should next insert the red test lead into the hot slot, and the black test leads into the neutral slot. Therefore, check the displayed number, which should be between 110 and 120 volts. However, 3, and 4 extended outlets are also possible. L-shaped neutral plugs are the most common type.

Connect your black test lead to a ground outlet and your red test lead to a live one.

After you’ve properly connected everything, the value of your voltage gauge should read between 220 and 240 volts. Your two slots will likely be at an angle if your outlet has three prongs, and they’ll be vertical on the outside of a four-prong outlet with the famous “two hot” slots.

Connect the test leads to the outlet’s slots.

The different colors of these jacks make it easier to tell them apart and make the correct connections.

The black lead goes into the minus sign of the negative blackjack, whereas the red lead goes into the plus sign of the positive blackjack. Input the two test leads from your tester into the multimeter.Conventionally, this is depicted by a wave line, while direct current is shown by a dashed and solid line in electrical symbols (DC). You should set your meter to work with alternating current (AC) by selecting a value between 220 and 240 VAC. Then, turn the multimeter’s selector knob to AC and use the settings closest to the outlet voltage to verify the reading. Put your multimeter on voltage measurement and turn on the power.In this case, the 220v outlet is probably a maximum two-pole breaker, as indicated by the label on the door of your panel. Make sure you know where to find the 220v outlet’s circuit breaker in the main electrical panel, which is typically situated in the laundry or mud room.For the ground wire, there is a half-circle marking for the neutral wire, a longer slot on the left and for the hot wire, a shorter slot on the right.

There is one that is cold, one that is hot, and one that is used to anchor things to the earth. Observe that there are three prongs in a standard plug. Do not ever let the metal ends of your probes touch doing so could cause an unsafe short circuit. Holding both probes of a multimeter in one hand is a good way to prevent accidental electrocution. Warning: You will be performing this test on a live outlet, so take all necessary precautions.

How To Check A 220 Volt Outlet With A Multimeter? About 120 AC volts should show up on your voltmeter. Connect the red probe’s metal end to any of the angled 120-volt slots and the black probe’s metal end to the ground terminal.
