Hi!
Please have a look on the attachment.

As you can see, four Ammeters are in same branch, but they measured different electrical currents. How can it be possible? It's well known that in one branch can be only one electrical current.

 

I suggest saving your design and see if that fixes the problem.

I have tried it, but nothing. It's interesting that addition of one Ammeter more changed previous state, picture bellow.

Yeah, Multisim does a lot of strange things, on more complex circuits there is also the problem that it just cannot simulate them.

If you have access to the Proteus VSM, try it out. Works much better and you can even simulate uC firmware.

 

Thanks praondevou, I will try Proteus
