This video tutorial is in the Home & Garden category which will show you how to use a multimeter to check for continuity, measure resistance and voltage and many more values. Multimeters are like the electrical engineer's Swiss army knife. Multimeters can be of digital or analog types. Before using the multimeter, make sure there is continuity between the two probes. When you connect the two probes with each other, it will beep indicating that there is continuity and then you can go ahead. To check continuity on a circuit board, connect the two probes to different points on the board and a beep will indicate there is continuity. You can watch the video for the full instructions.
