Precise DC voltage measurement using NI9219

[bannapure_smita]

While measuring  dc voltage across a resistor using NI9219 , the 3rd and 4th digit after decimal point of the  result continuously fluctuates .

To measure voltage coefficient of a resistor using either Elvis ii or ni9219, what method should be used?

Thanks in advance.

You have posted to a board for an obsolete product called "Measure". It is not a board to dump generic questions. The Multifunction DAQ board would be more appropriate though I don't see where you have a problem at all.
