We have the product which is generating the 0-25mA output current.We are planning to test it from the NI.
We have NI PXI 6259 card (AI).would you please help us, how to test it 0-25mA output current with 6259 card?

You can just use a 500 Ohm resistor in parallel with your signal. I would also add a buffer circuit to protect your DAQ. Or you can do a quick search for isolated converters.

If this will be a product quality related measurement, you have to look at uncertainties and traceability (calibrations) ...
For a quick and dirty check any 500 Ohm resistor from (or underneath 😉 ) the bench will do it (0.5W better 1W) , otherwise you have to look for a stable low tempco resistor....
