Do Not Use an Oscilloscope Without Watching This Video
Hello, our electronics friends who perform advanced electronic circuit repair know that an oscilloscope is indispensable. When measuring power with an oscilloscope, contact between the ground tip of the probe and the phase can cause a short circuit in the power supply, even serious injury. To avoid this, the oscilloscope should be isolated from the power supply using an isolation transformer. This protects both you and your equipment.
