in this video i demonstrated How To Measure Mains Un-Isolated AC Line Voltage With DSO Digital Storage Oscilloscope. Sometimes we need to measure mains live unisolated ac voltage voltages with oscilloscope. you must take special care while measuring voltages on the mains with any measurement instrument. The mains voltages are absolutely deadly because these have un-isolated supply. Measuring mains voltages with multimeter can be dangerous as well. but Trying measure mains voltage with oscilloscope is more dangerous, because typically oscilloscopes are are grounded devices that have the ground side of the probe connected to the equipment case. while making connection to mains voltage slightly wrongly can make a huge disaster causing short circuit, damage the probe, your oscilloscope or human injury. If you are trying to use a traditional bench oscilloscope that is powered up with main line volatge, ALWAYS MAKE SURE YOUR SCOPE IS GROUNDED BECAUSE THE GROUND IS THERE FOR YOUR SAFETY! 1. in this best choice when we need to measure mains voltage with oscilloscope is to use a completely isolated oscilloscope like battery powered oscilloscope or scope-meter. 2. if you need to use bench oscilloscope, then use an islolation transformer, in that case you can measure line voltage without any danger how to measure un-isolated voltage with dso digital storage oscilloscope measuring mains voltage with oscilloscope measuring mains with oscilloscope measuring mains voltage measuring un-isolated mains ac voltage how to measure line voltage how to measure line voltage with multimeter how to measure line voltage with oscilloscope digital storage oscilloscope tutorial, how to measure ac voltage with oscilloscope, oscilloscope to measure ac voltage
