Power Supply Testing/Tutorial on measuring the voltage with the multimeter


 * 1. Turn off the power supply.
 * 2. With the wire strippers remove the insulation from two wires. (One of the wires must be the black wire because its voltage is 0). Removing_the_insaltion_from_the_black_wire.JPGRemove_insaltion_from_the_other_wire.JPG Wires with our insalation.JPG
 * 3. Turn on the multimeter to 20 in the DC.
 * 4. The black cable from the multimeter: place it near the black wire.
 * 5. The red cable from the multimeter: place it near the other wire.
 * 6. Tape them. Measuring the voltage the correct way.JPG
