Hi AnalogKid:
Thanks for your replying. You said current flows through the lump sum parameter RIN nodes (1) and (2) regardless if VS- terminal 0 is connected to ground or not.
Then what is Rin? Rin is the resistor inside the 6250 board or the bias resistors from AI- to ground? Could you please tell me?
Attached is my graph. I take VS as the voltage across 100ohm resistor. Is that correct? I would like to verify with you.

Hi AnalogKid:
Attached is my graph. How does current flow at the point where bias resistor started? Could you please tell me?

Hi:
I would also like to ask the AI+ and AI-. input. I might ask before, but I forgot. The AI+ and AI- input can only measure AC and DC voltage, am I correct? no current.

Your schematic is incomplete, you do not show a connection to anything on the bottom side of the bias resistor.
Correct, inputs will only measure voltage directly.
