How To Measure 240V With A Multimeter

When measuring 240 volts with a multimeter, set the meter to the VAC (volts alternating current) setting. Touch the two probes together to create a circuit. Touch the black probe to one of the two vertical prongs on the outlet and touch the red probe to the other vertical prong. The meter should read 240 volts.

How To Measure 240V With A Multimeter

When measuring 240 volts with a multimeter, it is important to ensure that the meter is set to measure voltage. The voltage setting is usually indicated by the symbol for a battery, which is typically a capital letter V. Once the meter is set to measure voltage, ensure that the black lead is plugged into the COM port and the red lead is plugged into the port labeled V or VOLT. Touch one probe to each of the two terminals on the outlet or power source being measured.

Multimeter, probe tips, voltage source

  • Turn multimeter to the voltage setting
  • Put multimeter’s black lead in the com port
  • Put multimeter’s red lead in one of the two voltage ports touch the black lead to the ground wire touch

-To measure 240v with a multimeter, you will need to set the multimeter to the voltage setting and then plug in the probes. Touch the black probe to the ground wire and touch the red probe to the terminal that you want to measure. The voltage reading will be displayed on the screen.


Frequently Asked Questions

What Runs On 240 Volts In A House?

240 volts is the typical voltage in a U.S. household. Appliances that require 240 volts, such as air conditioners and ovens, will have a plug with three blades and two slots.

How Do You Know If You Have 240 Volts?

240 volts is the standard voltage in the United States and most other countries. It is what you will find in your home and in most businesses. If you are not sure if you have 240 volts, you can test it with a voltmeter.

How Do I Test A 240V Power Supply?

Testing a 240V power supply is as simple as plugging it in and checking to see if it turns on. If it does, then the power supply is likely functional. If it doesn’t, then there may be a problem with the power supply that needs to be diagnosed and fixed.


In Summary

240 volts can be measured with a multimeter by setting the meter to read volts. The meter will need to be plugged into an outlet and the black lead plugged into the hole labeled “COM” and the red lead plugged into the hole labeled “VΩmA”. Once everything is plugged in, the black lead should be touched to one of the bare wires and the red lead should be touched to the other. The voltage will then be displayed on the screen.
