Can someone please explain what the Val parameter is

I’m a hobbyist learning to use digital scope in the iCircuit simulator. Having fun and learning a ton but for the life of me I cannot figure out what the measurement Val at the bottom of the digital scope is. Can someone tell me what the acronym stands for and what I’m measuring???

From the manual it looks as though Val defines the position of the Value axis (Y-axis origin) for any given trace.

ICircuit has a few glitches. This is a minor one.
The "RMS voltage" it displays is actually the RMS voltage of the AC wave PLUS the DC offset. A Fluke multimeter should show just the AC volts mode would show just the RMS voltage of the AC wave and then show the DC offset in DCvolts mode. That may not be a glitch but just be aware of the iCircuit format.

As for the Val, that value matches the current value in the scope display at the right margin (mostly). The glitch is that it is that the little Voltage box on the display (right edge) is off from the Val by a few hundredths of a volt for some unknown reason. The value is off more if you use a custom range (i.e. Not the AUTO mode) on the scope voltage.

Also, the scope must be on full screen mode. I think it is essentially the current value in the simulation calculation whereas the display might be a few clicks behind.

thanks for the replies. Good to know i wasnt crazy and or that it wasn't something super easy exposing my noobism ;-). Thanks for the heads up on the glitches. BTW are there any better simulators out there. I choose iCircuit because its easy to use but seems to have a bit more depth and features than most apps. My second choice was everycircuit. Ive spent a lot of time playing with those two and learning them but if there is something better out there i wouldnt mind spending a few bucks. Thanks again for your help!

What platform/operating system?

Also be aware that easy and good seem to be an XOR pair. iCircuit and LT Spice are in two different leagues. iPad I like iCircuit. Desktop/Windows, I like a Spice-type simulator.

oh sorry windows. I have ltspeice and played with it quite a bit. I like it too for me its just a bit harder to manipulate being a self taught beginner. I guess I'm agreeing with you in that spice seemed to me to be a lot more detailed and accurate (i assume that's what you're saying 'in a different league"). If so maybe ill stick it out with spice. Its probably just a learning curve thing for me.

Yes, I meant that LTSpice is more detailed. Essentially a circuit analysis tool that you can graphically input a schematic. iCircuit is a Schematic Drawing tool that does some low-level simulation with generic components.
