I don't know what that could be. I've never seen a scope with any markings for time other than S, mS, uS and nS. I also can't think of any "1" setting for these categories that corresponds with 7 divisions, unless the frequency is *much* higher or lower than I've seen in these units. 7uS is roughly 140kHz. 7mS is 140Hz. Yes, we're discussing the lighting transformers with (supposedly) 12VAC output.

I just went and check my scope. On the sec/div dial there are 3 sections, S, mS and the backwards y with a tip on the short end which probably equates to your uS, and the setting I was using was 1 uS in that case.
If you really have a 140 kHz lighting transformer, it would be very helpful to know the model number. A pic of the inside when you have time would also be of use. Thanks!

I will take one in the morning and post it. It's bed time for this old fart.
