Digital Multimeters (DMMs) and Precision DC Sources

[Raikar]

                  I have a pcb having only few active passive component I need to measure continuity and the devices I don't want to use PXIe-6556 is it possible program by using DMMs if yes let me know how to program,is there any other way to test by using other device which is cost effective than DMMs

Hey Raikar,

The concept you're trying to implement is called 6-wire resistance measuring.  Here's an article that discusses the concept:

In short, you use an opamp to null out any elements in a particular node that you do not want current flowing across.  Let us know if you have any questions.
