I am looking at LJLogUD and I don't see "AIN1" anywhere.
I see row 0 offers boxes for CH+ and CH-, but that implies differential input to me.
I see Ranges "LJ_rgBIP10V" but I haven't found explanation of that acronym yet.
On row 3, I have entered Scaling Equation "y=1000*(a-b)" and turned on the green "Graph?" button, but I don't see anything under "Scaled" nor on the graph. (I am trying to monitor voltage and power [Vdrop across 10 ohms], so 3rd "channel" is synthesized from two previous inputs).
What does "199" mean under CH- ???

For a single-ended reading of AIN1, go to any row and set +Ch=1 and -Ch=199. 199 means ground so it is a single-ended reading.
The Range constants are defined here:

Your 3rd row is not doing anything because you have set #Channels=2. Even though your scaling equation is only using readings from other rows, you need #Channels=3 for that row to be active.
