Issue Details

I would like to take 4-wire resistance measurements in my cDAQ system. What are my options for appropriate hardware?


The NI-9219 is a cDAQ module capable of doing 4-wire resistance measurements. Specifications such as input range, accuracy, and stability for 4-wire resistance measurements using the NI-9219 can be found in the device datasheet .

Additional Information

Multifunctional DAQ devices can also be used to measure the impedance of a resistor indirectly by following the procedure detailed in the Resistance Measurement with Multifunction DAQ  article.

A good alternative to using a cDAQ module for 4-wire resistance measurements without upgrading to a PXI system is one of our stand-alone or computer-based Digital Multimeter (DMM) devices. These devices typically have higher accuracy and resolution than the NI-9219 for 4-wire resistance measurements, which can be found in the respective device datasheets.
