how do i measure exact value of resistance measurement in DAQ-6224
I want to measure resistance measurement in DAQ-6224 in power off condition (I.E cold test condition such as using mulitimeter) . I have Gone into MAX or the DAQ Assistant and setup a DAQmx Task. In (Measurement and Automation Explorer), right click on Data Neighborhod and select Create New. Select NI-DAQmx Task. From there, select Acquire Signals > Analog Input > Resistance. Selected the 6224 module and the appropriate channel(s) i want to connect up to. The next window will be the channel configuration window. By default, 2-wire mode i have selected. At the bottom of that screen, i have seen "Connection Diagram". By running the program its not showing the exact measurement value always it showing different values .how to over come these problem ? can any one suggest with exact example 
Can you show your full DAQmx channel setup? Measuring resistance can be a somewhat tricky experience. It only takes 1 wrong setting to mess it all up.
Just played around with a simulated 6224. That device does not have an internal excitation. Therefore, you will need an external constant current source to supply the current across your resistor.
