Is My Scope Screwed for AC Testing
Okay, just found a 125VAC connection in the set (feeds the front panel lights). I measured with my DMM and got 117.8VAC. I then set my scope to AC coupling, 50V/Div and probe in 10x so I should see a waveform taking up roughly 2.3 divisions as the AC is 117VAC. I'm attaching a picture of what I got and you can see the settings on the scope. I'm no expert, but I don't think 117VAC should take up 6.5 division for a voltage of roughly 325V.
Am I wrong? Is this a problem with the scope, the probe or (hopefully) user error?
