Ohm Meter Max Out

Redstone's circuit ( https://everycircuit.com/circuit/5727639482138624) got me wondering about the highest resistance the EC ohmmeter can read.  Looks like it's around 10GΩ.  Anything past that reads open circuit. 

The left resistor ladder is 10GΩ, which the ohmmeter registers correctly.  The right resistor combination is 10.0001GΩ which registers as infinity.  Flip the switch to select one or the other.

I think this is a pretty good simulation design rule because any resistance over 10GΩ is practically an open circuit or insulator anyway.

Some kinda crazy things are going on, though, in the left circuit.  100pA is very low for the simulator, so some resistors in the series circuit read 0A, breaking Kirchhoff Current Law (KCL)!

Anything below 100pA is displayed as 0.

Yep, that's what I was trying to get at there. 100pA is probably the lowest current limit for EC, so it starts having some trouble with current that small.
