What I found to be working is to place one terminal of the R_series at the ground and the other at the LED terminal. Then, the ground probe is connected to neutral and the Ch 1 probe is connected to the R_series's terminal which is connected to LED's terminal. Doing this is way, nothing blew up. | |

| Feb 9, 2016 at 23:44 | comment | added | Qelopin Uacel | I didn't describe it accurately. What I mean by opening the switch is actually just plugging out the AC power plug from the socket. So I think the my diagram is correct. | |
| Feb 9, 2016 at 20:19 | comment | added | Peter Green | "All oscilloscopes are "mains-Earth" grounded." most are and you should certainly assume a scope is until proven otherwise but scopes with non ground-referenced inputs do exist. | |
| Feb 9, 2016 at 18:21 | comment | added | rdtsc | The switch must be wired in such a way that "open" was not quite accurate. Is there a name, part number for the switch? And how was it wired? | |
| Feb 9, 2016 at 17:13 | comment | added | Todd Wilcox | @QelopinUacel How much do you know about the switch you opened up? Was it a double-pole switch as the diagram seems to indicate? Could it have been single-pole? | |
| Feb 9, 2016 at 16:11 | comment | added | Qelopin Uacel | With no voltage source from the grid, where did the energy that blew up the R_series come from? I've seen that this LED tube contains several electrolytic capacitors in its driver. Did the energy come from these capacitors? | |

Typo, added math-mode illustration.
