Just bought a new UPS for my home office. The old unit has a "simulated sine wave" and the new unit advertises a "pure sine wave". So, just for fun, I would like to see those sine waves on the screen of my oscilloscope.
I have a GW-Instek GDS-1072b oscilloscope. According to the
datasheet, it can handle 300Vrms. I'm in Thailand, where the grid provides ~230V so I think that should be ok.
What I know is that I must disconnect the UPS from the wall, to ensure it's output is floating and of course to make sure I get the output from the battery rather than what is passed through from the grid.
Maybe the probe needs to be set 10:1?
What else should I be thinking about?
Is it safe to just be hooking this up?
It's not exactly critical analysis, but I thought it would be fun to see!
