using 6052E card to measure current

I did not know, but a simple search can provide an answer:

oh, an extra information i have is that i also have a pxi4060

Its a digital multimeter card?

sorry, i am very new in using these cards so i don't know how to use them.

The PXI-4060 is a DMM card that is no longer sold by NI.  If all you are looking for is a short, open, or nomial it will work wonderfully by just doing a simple 2-wire resistance measurement.  If you need more accuracy, use the 4-wire method.  This would be a lot simpler than measuring voltage from a shunt resistor, calculating the current, and from there calculating the system resistance.

hmm, so you are suggesting that i learn how to measure with the pxi4060 card instead of using the stunt resitor method?

so to apply 10V to my circuit, i would use the 6052E analog output and use the PXI4060 to measure the current from that?

No, the DMM can measure resistance directly.  You don't need to apply anything external.  Simply hook up the + and - leads from the DMM to the system and measure the resistance.

hmmm, 

my resistor is inside a case.

it cannot be open to directly put a two probes in there.

i was thinking that to apply 10V, measure the current and calculate for R.

[crossrulz]

Why can't you apply to the leads to where you were planning on putting the 10V?

[krispiekream]

I dont think I will get the R value because there are other things involve..

where i am planning on putting the 10V is at the CASE and other other RED probe

[crossrulz]

You'll get the same results as you would by applying 10V.  In fact, you are just copying what a DMM does to measure resistance.  I understand the issue with having other circuitry.  What I have done in the past is setup the resistance measurement, wait so long (1 second should be more than enough) and measure again.  Keep the second measurement.

ill give it a shot right now..

i am using the NI 4060 soft panel and I was about to read 10V but not sucessful in duplicating what my multimeter is reading.

18.3 uA is what I was getting but I guess i am not getting that with my card..any clue?
