How do I determine Source Resistance ?

[nknight]

I need to determine the value for the bias resistors for my
differential analog input channels on my AMUX-64T board. We typically
measure 4-20mAmp DC signals from Ohio Semitronic power transducers.
The transducers do not have a specification for "Source Impedance" or
"Output Impedance" for the 4-20mA sources.

Is there a way for me to measure this easially ?

Hello,


I do not consider myself a circuit expert, so I used Google. Here is a result that I found. Hopefully this helps!
