Though the symptoms of a short circuit can be similar to an open circuit, diagnosis is a bit different. If you purchase something through this link, I will earn an affiliate commission. Follow our tips for finding and fixing ground faults and short circuits. As a result it is important that people are aware of how to use an oscilloscope.

Even if you're not a technician or an engineer, some printed circuit board problems are obvious. These need to be set correctly if the required view of the signal is to be obtained.Fortunately it is quite easy to get used to operating an oscilloscope and using the controls to be able to view the waveform correctly.A summary of the main controls on an oscilloscope is given below:Nevertheless, a short overview of some of the controls is given below: 1.
