How to Test DC Power Supplies with a Multimeter.

This is a basic demonstration on How to Test DC Power Supplies with a Multimeter. DC power supplies are actually AC to DC Adapters and are commonly called "Wall Warts." This quick and simple test will let you know if the power supply is working or not. Keep in mind that you are testing the power supply in a "no-load" condition so you will most likely get a higher reading than what is stated on the power supplies label.
