using 6052E card to measure current

[crossrulz]

How do you have this hooked up?  Were you using the 4060 in the Resistance mode?

[krispiekream]

I am using it in current mode...

i probe at the same position as my multimeter.

The 4060 should be hooked up just like your multimeter and set to measure resistance (bottom left button with the Omega and small "2 wires").  The 4060 is a multimeter (hence DMM).

even with my hand multimeter, 

when measure resistance across my circuit, i get an "OL" (overload).

I dont think I am able to measure resistance.

I can measure the current with my multimeter and NI DMM Soft panel but never resistance...

Am I doing something wrong?

That sounds like a problem with your circuit.  Once you get it to work with your hand DMM, it will work exactly the same with the 4060.

The circuit you posted earlier will measure open with a multimeter unless whatever is connected in parallel with C2 draws some current.  The 18 uA that you reported measuring corresponds to 546 kohms with a 10 V source.  If the circuit not shown is an active circuit which only draws current when the voltage is several volts or higher, that could explain the resistnace measurements being low.  Most modern multimeters only apply millivolts to the circuit under test.

Tell us what the rest of the circuit looks like and what you are really trying to do.  You mentioned short circuits in an earlier post.  What do shorts have to do with these measurements?

Are you applying the 10V while trying to measure the resistance?  Don't do that!  That will mess up your measurements.

So just to be clear, do not apply 10V, hook up your 4060 leads (the voltage leads, not the current) to the box and measure the resistance.

That's not true.  Only milliOhm meters.  Most DMMs will put out up to 10V.  Here's the 4070 data sheet for reference.

Thanks.  I have never used any of the plug-in DMMs.
