Negative 'not_measured' values

Ok, can I check all my 240 volt plugs that same way? It seems that all of them have two wires going into the double breaker (black and red) and one going to the bar to the side with the white and some green wires.

If I see that any of the 240 volt breakers have no voltage on the white wire going to the neutral bar then I would run the ct with both red and black through it in opposite directions, and if I do see voltage I would run one wire through and just check the ‘double’ option?

It’s current, not voltage, but yes, you are looking for zero Watts on the white. It’s the other way around. If you see a non-zero value, you need to capture both the red and black (one opposite the other). If you see zero on the white while the appliance is running, you can just capture either the red or black and “double”.
