PCI-4472 -- Measuring Resistance

Highlighted
Is it possible to measure resistance with a PCI-4472 DAQ card? When I use the DAQMX create measurement channel.vi and set it to resistance measurement I get a error message saying 'this physical channel cannont measure resistance, please select voltage....'

This card measures voltage. To measure resistance you need to measure both voltage and current so you need a source of some kind.

The PCI-4472 is a DSA (Dynamic Signal Analyzer) variety of DAQ board.  This means it is optimized for measuring dynamic signals and accurately measuring the frequency components.  To measure resistance you will provide a current as gwd mentions, and read back the voltage.  You will need to take at least 2 measurements (a requirement of the DSA design).

From the voltage measurement you can scale using Ohms Law (R=V/I) to determine resistance.
